|
|
In 1980, when CUCC started to explore the new route in Stellerweghohle,
|
|
surveying was, for the first time, considered a priority. So it was that
|
|
a party of two surveyed from the Big Pitch to the head of the Big Rift
|
|
using the CUCC Suuntos. The same surveyor returned a few days later with a
|
|
different companion, to survey out from the Big Pitch to the entrance, this
|
|
time with the EXCS Suuntos.
|
|
Back in the camp, calculators were punched, coordinates scribbled, and the
|
|
survey hastily drawn up. The surveyors looked at each other in some
|
|
confusion. The cave seemed to be floating, airborne, across the valley and over
|
|
a cliff. Unable to recall that it had been in daylight with a sense
|
|
of exposure, they came to the conclusion that it was plotted in the wrong place.
|
|
The surveyors retired to the Bar Fischer to consider the dilemma. All
|
|
problems dissolved in a haze of Reininghaus beer fumes as the truth dawned.
|
|
One R.J. Shackleton, who had been is possession of the EXCS compass for
|
|
some time, was in the habit of storing it in the top of his fridge. This has
|
|
resulted in a slight magnetic adjustment, so the survey was now plotted not
|
|
to grid- or true-north, but to fridge-north! What was needed was a little
|
|
calibration, so, armed with a map, both compasses, and several more bottles of
|
|
ale, the party set out to take bearing on local landmarks.
|
|
An hour or so later, it was decreed that the compass was 134$+o $l in error and the
|
|
survey redrawn accordingly. Since it was now inside the hill, all seemed to be
|
|
well. The compass quietly vanished from sight and all accompanying evidence
|
|
was destroyed.
|
|
1981 saw a connection between Stellerweg- and Schnellzughohlen, but serious
|
|
surveying was carefully avoided. 1982 saw CUCC at the bottom of the system,
|
|
and a lot of surveying was undertaken to avoid ever going there again, but
|
|
Stellerweg was not rigged and hence the biggest closed loop kept its secret.
|
|
1983, and our heroes connect the new entrance, 142 (ne$o'e 132), into the system.
|
|
Now comes the critical mistake. Wide-eyed, innocent and pleased with the glory
|
|
brought by pretty surveys, CUCC connect everything together with a half-mile
|
|
closed loop through 142.
|
|
Back in England the greedy computer devours all the numbers and prints out the
|
|
misclosure, about two inches vertically - pretty good that eh? But what's
|
|
this? Just over a Quarter of a Mile out horizontally?!?!?!?
|
|
Detective work soon revealed that a slight rotation would make Stellerweg
|
|
fit very nicely. In fact, the figure turned out to be 46$+o$l. But 46+134 = 180.
|
|
And 180$+o $l is a much more probable figure for a compass error than 134$+o$l. Also,
|
|
when the compass was traced, a sober experimenter found it had precisely the
|
|
error expected. Thus, the survey as published should rotate the section from
|
|
the entrance to the Big Pitch by 46$+o $l clockwise. The streamway from the Big
|
|
Pitch to the Big Rift needs translating appropriately, and the conveniently
|
|
unsurveyed Big Rift is a lot shorter than shown. None of the remainder of the
|
|
system was surveyed with the duff compass, but a big section of the
|
|
Sonnenstrahlhohle survey is also wrong, but that didn't have a north arrow
|
|
anyway (guess why!).
|
|
It is expected that the survey will be redrawn correctly when enough
|
|
additional passage has been found to justify the work involved.

The entrance lies 21m vertically below and 65m on a bearing of 94$+o $l from the
|
|
nipple at the end of the ridge running SSW from the Vd. Schwarzmoos Kogel.
|
|
The 7m entrance shaft narrows to a squeeze through a slot to loose boulders
|
|
at the head of a 9m pitch down to a floor of large wedged blocks. A 16m
|
|
pitch down through a slot lands on a balcony at the start of a large shattered
|
|
shaft, 13m wide in places. This is passed by pitches of 15, 42, 5, 7 and
|
|
23m (belayed from a nipple on the opposite wall). The cave closes down to a
|
|
triangular slot 50cm wide, and a 13m hang against the wall drops into a short
|
|
section of horizontal passage with phreatic roof scalloping. This turns into
|
|
a traverse as a small stream in a canyon comes in from the left, and the
|
|
route follows this down as a 28m pitch to land in a pool. A short drop and an
|
|
11m pitch break into a level of extensive phreatic development. Following
|
|
the stream down a series of ramps leads to a large abandoned passage which
|
|
has not been explored.
|
|
From the foot of the 11m pitch up a boulder slope, past a steep ramp to
|
|
the left leads to a series of small phreatic tubes which soon close down;
|
|
straight ahead, into a passage almost filled with layered mud and with a
|
|
strong inward draught, breaks out at the top of a large chamber, which is
|
|
descended down a layered mud wall. On the opposite side a large passage is
|
|
inaccessible, but thought to represent an important way on to Stellerweghohle.
|
|
From the bottom of the chamber, a 7m diameter tube slopes down at 60$+o$l#
|
|
for 40m. This turns vertical at a 14m pitch which caries a small stream to
|
|
a 10m pitch, after which the stream vadose canyon gets too tight.
|
|
By swinging off the 14m pitch half-way down, a continuation of the main way
|
|
is reached. This is a 10m abandoned passage with dusty blocks and layered mud.
|
|
After 20m this closes down in a small chamber. Dropping down 13m in boulders
|
|
leads to a very small canyon; a passage on the other side of the chamber
|
|
continues as a canyon for 30m, but filled with mud. The final route out is
|
|
a 1m diameter, almost circular, phreatic tube with a small vadose trench in
|
|
the floor. This continues up at 35$+o $l for 70m, until it meets a very small trench
|
|
which draughts out. The tube elbows back on itself, but soon becomes choked
|
|
with mud as the small invading stream disappears down a crack.

..astart 'Caves Of The Cape Peninsula' 'Brian Derby' 19
|
|
..blank 4
|
|
The Cape Peninsula stretches from the surrounds of Cape Town southwards towards
|
|
its termination in the Cape of Good Hope and Cape Point. The terrain is the
|
|
classic Fimbost, a rugged country of exposed rock and loose sand covered by
|
|
native Protea plants and newer immigrants such as Wattle. The geology is mostly
|
|
sandstone, though there are a few exposures of limestone. This area of South Africa
|
|
is not renowned overseas for its caves, the region further inland with its Kango
|
|
caves is much better known. However,
|
|
the Cape Peninsula is very interesting because its
|
|
caves are in sandstone. The morphology of the cave passage is very similar to
|
|
limestone caves and there is a considerable horizontal development (a maximum
|
|
reported of 400m+), though nothing significant vertically.
|
|
Two distinct types of cave are evident, the classic rock-shelter and the more complex
|
|
cave analogous to limestone development. Two rock shelters are worthy of mention;
|
|
Elephants Eye cave in Constantiaberg which is a large entrance visible for many
|
|
kilometers, and Muizenberg cave which has a smaller rear entrance passing through
|
|
the mountain and has evidence of Stone Age habitation. These rock shelters
|
|
appear to be classic erosion features in soft rock, the rear entrance in Muizenberg
|
|
cave is related to a fracture in the rock. These caves which are little more than
|
|
surface features, are widely distributed in the region. The more interesting
|
|
and more complex caves are confined to one small part of the hills of the peninsula.
|
|
Behind the coastal towns of Muizenberg and Kalk Bay is a small range of rocky
|
|
hills. Here three hills, Kalk Bay Mountain, Ridge Peak and the aptly named Cave
|
|
Peak contain over eighty caves. These vary in complexity from Avernus, a small
|
|
chamber with two 10m entrance passages to Ronan's Well with over 400m of tight
|
|
strenuous passage.
|
|
The surface morphology of the hills are strangely karst-like,
|
|
though sink features are absent.
|
|
I did make the elementary acid test on the rock and it didn't seem calcareous.
|
|
To reach the very top
|
|
of Cave Peak required a scramble and easy climb.
|
|
The cave entrances were at the foot
|
|
of a summit block where a steep slope intersected a 10-20m crag.
|
|
The hilltops are of exposed rock, highly eroded and faulted.
|
|
The cave
|
|
development is controlled by these faults, chiefly vertical faulting though
|
|
some features show a definite influence of the horizontal.
|
|
A typical and very popular cave is Boomslang Cave. This cuts the ridge,
|
|
offering an easy through trip for many a local hill walker.
|
|
The "front entrance" of the cave is typical of the caves I saw. A vertical fault
|
|
intersecting a rock face had been eroded deeply into the face, the entrance
|
|
was at the back of a small ravine above a pile of boulders. The passage continued
|
|
along the line of the fault, usually it was about 2m wide and up to about 15m
|
|
in height. When we were maybe 40m or so inside the cave a hole was visible in
|
|
the roof; a search on the surface failed to find this pitch entrance.
|
|
The passage closed in and a stoop round led to a little chamber with about
|
|
10cm of water on the floor. There were three or four ways out of this room, one
|
|
got low and wet very quickly, another led into a wide passage of stooping height
|
|
and then into a largish circular chamber of about 10m diameter. From this chamber
|
|
there were several small passages one leading back into the chamber and two
|
|
leading to the outside world on the other side of the ridge. We took one of these
|
|
and it too was associated with a visible vertical fault. However about 5m from
|
|
the new entrance the passage entered a little widening and the exit was controlled
|
|
by a horizontal fault which created a small flat-out crawl.
|
|
Following this, we exited having tunnelled completely through the hill.
|
|
The cave passages between the crawl and the main chamber were dry and their
|
|
floors were covered in a coarse grey sand. The passages associated with the
|
|
vertical entrance fault had a thinner sand flooring and also had extensive
|
|
damp or wet lengths. The presence of water suggests that these are erosive
|
|
rather than tectonic features, although development is clearly controlled
|
|
by the extensive faulting.
|
|
Sandstone caves are not unique to this region of the world, French expeditions
|
|
to Venezuela found huge sheer sided pits (two hundred metres deep!) in the
|
|
sandstone Roarima (Lost World) region. These pits had cave passage at their
|
|
bottoms. Although there are no similar caves in Britain the sandstone in the
|
|
Orkneys has huge sea eroded gorges many times longer than they are wide in its
|
|
cliffs, these "geos" are similar fault controlled structures.

A possible dig was identified in the higher regions of the Metallurgy
|
|
Annexe Massif. The geology was mostly silicaceous but there is a definite
|
|
banding of limestone visible on exposures. The dig was opened when a poised
|
|
jammed cast-iron "boulder" was freed. This revealed a window onto a
|
|
large pitch, this was measured as 50ft.
|
|
The pitch, an unbroken hang against the wall, was descended the next day.
|
|
The bottom was choked and all possible extensions closed in
|
|
after a few feet. The system is dry and filled with a loose black dust. There
|
|
is a possible boltable extension to an upper entrance, this could be one of the
|
|
many chimney-like structures visible on the plateau. If this were pushed a
|
|
total vertical range of 25m (80ft) would be achieved.
|
|
The explorers do not think this is part of the sub-magog system and it
|
|
does not bring any nearer the second entrance to Royston cave.

'I've done some work on mountaineering ropes. Do you want me to give you
|
|
an article for the journal?' I said .....
|
|
..blank 2
|
|
I must have been feeling charitable at the time, since having just
|
|
written page after page of the official project report (the 'work' referred
|
|
to being my final year engineering project), the very last thing I felt
|
|
like doing was going over it all again. Anyway, I've done my best not just
|
|
to regurgitate it, but provide something of interest to cavers, since some of
|
|
the breed actually use this rope as their SRT cowstails and safety cords.
|
|
Whilst the opportunity presented itself, I also tested one or two caving
|
|
lifeline ropes as a check on their safety.
|
|
The tests I performed fell into two categories; drop tests, and tensile
|
|
tests. The drop test rig (see figure 1) is meant to simulate the conditions
|
|
a rope experiences when it arrests a mountaineer's fall. Because the rope is run
|
|
through krabs, any fall means the rope will be dragged over and bent round
|
|
a krab edge - a radius of about 4 or 5 mm. Thus the drop test is not a straight
|
|
drop, but is carried out over an edge.
|
|
The UIAA have set a standard test because of the infinite possibilities
|
|
of krab placement in a real rock climb. This is shown in figure 2. As may be
|
|
seen, the laboratory test is much more severe than the UIAA test but, dare I
|
|
say it, due to a somewhat lethargic attitude by the laboratory technicians
|
|
and limited space, I was lumped with what I'd got.
|
|
Tests were caried out to investigate the cumulative damage effects of a
|
|
number of falls of a given fall factor. Here, I must explain what the term
|
|
fall factor means:
|
|
..blank
|
|
Fall factor, $bn = (total length fallen)/(length of rope supporting fall)$b
|
|
..blank
|
|
A little thought will show that this can only lie in the range 0 to 2.
|
|
Numerous recent articles in the Caving Press (with which you are all, no
|
|
doubt, familiar) stress the fact that it is not the length of drop, but the fall
|
|
factor which is important in determining the severity of the fall. (ref,
|
|
$bRamsden, Paul: Cave Science vol9, no4, pp290-299, Dec1982$b).
|
|
Falls of magnitude n=2 can certainly happen in leader falls in mountaineering,
|
|
and it is not difficult to imagine the same situation for a caver using his
|
|
cowstails on (say) a traverse line at a point where he must climb above it
|
|
as far as his cowstail allows.
|
|
Anyway, I needed some graphs of, for example, retained rope strength against
|
|
number of falls, and since you can't (well, I can't) draw graphs on just two
|
|
points, I had to find a value of n which would give six or seven points (ie.,
|
|
you could drop the rope six or seven times before it broke).
|
|
I tested both 9mm and 11mm diameter ropes as these tend to be the popular
|
|
sizes used in "half-rope" and single rope climbing techniques respectively
|
|
(well, actually this happens to be true, but I had nothing else to test in
|
|
any case). Single ropes were tested since even in the "half-rope" (two
|
|
separate 9mm ropes) method of climbing, it is possible for just one of these
|
|
ropes to sustain the entire fall if the system has been badly rigged.
|
|
n=0.8 and n=1.4 gave acceptable numbers of results for 9mm and 11mm ropes
|
|
respectively.
|
|
The ropes used were of 'kernmantle' construction (fig. 3) consisting of a
|
|
bundle of cords, held in place and protected by a woven sheath. The cords were
|
|
made up of three 'strands' twisted together, the strands themselves consisting
|
|
of many fine nylon fibres. Equal numbers of right-hand and left-hand 'twist'
|
|
cords were contained in each rope.
|
|
The plotted trends of retained rope strength, and extension to failure
|
|
against number of falls showed a decrease (for 11mm rope) from 43kN at zero
|
|
falls to c. 12kN after five falls (this last specimen being severely damaged,
|
|
the sheath and some internal cords severed), and 35% at zero falls to 23% at
|
|
five falls. The 9mm was equally dramatic, equivalent numbers being 15kN to
|
|
5kN and 35% to 22% after five falls.
|
|
..blank
|
|
..page ~%page+1
|
|
So! What was causing these failures?
|
|
When a climber falls on his rope, the peak force in the rope (assuming
|
|
rigid belays and climbers, and no damping) can be shown to be given by
|
|
..blank
|
|
$bF$-max $l = W [ 1 + sqrt (2n/s + 1 ) ]$b
|
|
..blank
|
|
..tabset 12l
|
|
where $t W = climbers weight
|
|
$t n = falls factor
|
|
$t s = rope stretch as a fraction of initial rope length when the force
|
|
W is applied to it (ie., static percentage stretch when the climber sits on
|
|
his rope).
|
|
Credit for this nasty really ought to go to Steve Roberts because he wrote
|
|
it down first, but I think I can say with modesty that it would have come out
|
|
in the wash anyway.
|
|
Typically, for 11mm rope, s=0.03, n=2, and W=800N, then F$-max$l=12.6W=10kN,
|
|
ie. about 25% of the ultimate tensile strength (UTS) of a new 11mm rope.
|
|
Now during a fall, the rope is stretched, but does not fully recover
|
|
elastically. This leads to a lower value of s. Looking at the equation above,
|
|
it thus increases F$-max $l on subsequent falls. This longtitudinal stiffening
|
|
of the rope, with subsequent increase in peak load, is not in itself sufficient
|
|
to cause failure. Also, the climbers body, harness, and rope friction all add to
|
|
damping in the real case, reducing peak forces.
|
|
The implications for SRT ropes are much more serious however. By their
|
|
nature they are low stretch (otherwise we'd all be prussiking on climbing
|
|
ropes) and so peak forces are much higher, damping is also less. The lesson is
|
|
obvious: SRT ropes should not be used in situations where they may have to
|
|
sustain falls (eg., lifelining) and in normal SRT use this is not the case.
|
|
..blank
|
|
However, I digress.
|
|
It was found that severe abrasion occurred at the "edge" in each of these
|
|
drop tests, due to the rope being dragged over it in tension. This abrasion
|
|
caused a gradual decrease in UTS, and once the sheath was ruptured, all the
|
|
central cords were immediately vulnerable to abrasion (fig. 4), leading to a
|
|
rapid fall in strength with increasing numbers of drops. (In fact, in nearly
|
|
all the tests, once the sheath had been torn through, the subsequent drop led
|
|
to failure, despite the sheath only representing some 20% at most of the rope's
|
|
UTS).
|
|
To conclude, in new rope, the decrease in UTS due to abrasion and increase
|
|
in F$-max $l due to increase in stiffness eventaully cause failure by tensile
|
|
overload. Failure always occured at the edge where stress and abrasion were
|
|
concentrated. We may be thankful that in caving use, our cowstails, although
|
|
bent round the edge of karabiners in the end knots, are not usually subject
|
|
to severe abrasion.
|
|
NB: One area of rope weakening that I was unable to investigate
|
|
sufficiently was that due to environmental degradation and fatigue. As an
|
|
indication, a 10 year old 11mm rope (not kernmantle), which had sustained two
|
|
severe falls, numerous small falls, and considerable later use for hauling
|
|
equipment up rock slopes was found to fail at c. 9-10kN, ie. one quarter of
|
|
its new counterparts strength, or alternatively would only sustain a fall
|
|
of n=1.4. (These results were independent of the amount of surface abrasion).
|
|

|
|
Now to the caving lifeline.
|
|
I tensile tested one sample of each of four specimens, namely:
|
|
a) New Braidline (1984)
|
|
b) Old Braidline (2 years old)
|
|
c) Old hawser-laid 14mm diameter
|
|
d) Old hawser-laid 12mm diameter
|
|
Both hawser-laid ropes were "pretty old" but I had no details of their
|
|
age, other than that they were older than the Braidline. It had been decided to
|
|
retire the hawser-laid on the grounds that it was now probably unsafe.
|
|
The tensile test results were as follows:

|
|
(Assuming that knotting the ropes leads to a reduction in strength to 60%
|
|
of the initial value).
|
|
The value of 60% is debatable, but figures using it show that even the
|
|
grottiest bit of hawser-laid is actaully stronger (but not safer) than our well
|
|
used Braidline. Perhaps some more tests are called for (it could not be
|
|
ascertained what reduction in strength the grips caused in the Braidline).
|
|
These figures for F$-max $l are a bit close to the UTS for comfort. However,
|
|
there are reasons to believe that a caving rope deteriorates pretty rapidly on
|
|
its first few trips, but after that, its mechanical properties tend to level
|
|
out. It is fair to assume that this has happened for all the used ropes. It is
|
|
also fair to assume that in all caving circumstances, the worst possible fall
|
|
encountered whilst lifelining would be n=1.
|
|
So, it is safe to use all the ropes tested with the possible exception of
|
|
the 12mm hawser-laid, but the Braidline should be regularly tested again to
|
|
check for any further deterioration in strength.

..astart 'A Trip to Bulgaria' 'John Bowers' 21
|
|
..blank 4
|
|
I think I went caving in Bulgaria - wandering through Sofia at midnight with
|
|
trams clattering out of the fog, grovelling along a cold, tearing rift
|
|
400m down, or laughing at Bulgarian jokes only made intelligible by a fourth
|
|
glass of brandy - it was all barely real, but I am pretty certain that I spent
|
|
a week in Bulgaria, visiting five caves.
|
|
..blank
|
|
The cast was:
|
|
John Bowers, that's me.
|
|
Bev Wilson, of SUSS who have maintained contact with Bulgarian cavers for
|
|
many years.
|
|
Andrzey Monkowski, Warsaw Speleo Club, and the Akademik Club of Sofia, who
|
|
have entertained many English cavers.
|
|
..blank
|
|
The plane deposited us at Sofia at midnight from where we were whisked away
|
|
for the first of many drinking, eating and socialising sessions. It was also
|
|
then that the news was broken that the Akademik Club had discovered the
|
|
deepest pot in Bulgaria, and it was still going and I was to be involved in
|
|
a trip. After the initial excitement, I started to wonder. A big advantage
|
|
of Bulgarian caving is its very high bullshit to effort ratio. Its unlikely
|
|
that many English cavers will have done the same trips; a little gentle caving
|
|
and a lot of imagination can provide a large fund of stories with which to
|
|
bore people during the long, wet winter evenings in the New Inn. So what was
|
|
the point of doing a hard trip?
|
|
A couple of days sightseeing, two pleasant caves in the Douhlata area and it
|
|
was off up into the mountains above Vratza. Drive up by great limestone
|
|
cliffs, through golden brown forests and on to a plateau with views of the
|
|
Balkan mountains stretching to the horizon. The plateau is well endowed with
|
|
dolines, interesting looking holes, and little water. Many of the caves have
|
|
required digging to gain entry and there are now a number of entertaining,
|
|
well decorated trips. One of these is Barkite 18, discovered in September 1983.
|
|
A short dig led into a crawling streamway for a few hundred feet to a
|
|
boulder strewn chamber, the bottom of a ramp that leads up at 30$+o$l. At
|
|
this point you have to take your wellies off and clean up before padding up
|
|
flowstone, squeezing past stalagmites to the stal choke at the top.
|
|
Unfortunately, not all the caves are as pleasant, Barkite 14 wasn't.
|
|
Barkite 14 was discovered several years ago and had been extended over a
|
|
number of expeditions as various constrictions were passed. The pot was now
|
|
360m deep and still going, and we were to have the next pushing trip. The
|
|
party consisted of two Bulgarians (Peter Bervn and Phillipe), one Pole
|
|
(Andrzey) and me. I had been plied with stories of how grim the place was, but
|
|
the entrace series was an enjoyable chamber down a long flowstone ramp. Not
|
|
too bad this - should be out in time for a quick beer, what was all that talk
|
|
about an overnight trip? But it changed dramatically, as the roof dropped to a
|
|
nasty flat out wriggle to an awkward squeeze onto a pitch. And it never really
|
|
got much better. A slow descending narrow rift. An odd pitch, a bit of a duck,
|
|
just on down the rift for several hours. Then the walls parted to reveal a
|
|
black shaft, leading to.... the bottom just out of sight, 20m below. We didn't
|
|
reach the sump that trip; the next party down took in even more tackle to
|
|
find the final pitch just round the corner.
|
|
Our exit was uneventful, if slow and cold. On emerging to a beautiful early
|
|
November morning, Andrzey and I decided to take a short cut back across the
|
|
hills. Several hours later we were still thrashing through the woods with
|
|
Andrzey swearing at me in Polish as we struggled up the wrong hill yet again.
|
|
Somehow, by mistake, we found the path back to camp, for a celebratory slab
|
|
of bread and sausage, a little sleep, and a glass too many of brandy.

..astart 'Wolfehohle - Act I' 'John Bowers' 5
|
|
..blank 4
|
|
With the bottoming of Stellerweghohle, some of the older members felt it
|
|
was safe to return to Austria and the attractions of lemon ice creams,
|
|
gooey cakes and a little idle prospecting in the sunshine soon had the might
|
|
of EXCS racing their bath chairs along the autobahns to Altaussee.
|
|
The advantage of age is that it provides the experience so valuable in the
|
|
act of prospecting. Don't bother with the big open shafts, they always choke
|
|
in snow or boulders - look for a horizontal draughting entrance not too far
|
|
from the road. So the first find, 140, was a loose, open rift, just below the
|
|
summit of Schwargmoos Kogel, and miles from anywhere. Bunde lashed arms and
|
|
legs were endemic, and no-one was too sorry when it inevitably choked at
|
|
-100m, and even Julian couldn't be forced through the final boulders.
|
|
Ambling down from 140 after a surveying trip, John and Julian deviated from
|
|
the normal route and happened across Wolfehohle. Its main entrance lies 18m
|
|
above 82, and is a 2m high, 1m wide walk in passage complete with an icy
|
|
outward draught. From the start, Wolfehohle had all the symptoms of going
|
|
horribly deep - see next years journal to see if it lives up to its promise.
|
|
The two explorers, minus lights, felt their way along the passage, throwing
|
|
stones ahead to test for a drop, but it was soon obvious that shorts and
|
|
T-shirts alone wouldn't be adequate to push the pot to its end.
|
|
The next day Ben, Naomi, Julian and John finished derigging 140 and with
|
|
armfuls of rope romped off down Wolfhohle. A rapid bolt and the team surged on
|
|
down the 19m pitch into a chamber complete with the skeleton of a wolf
|
|
who had fallen in via another entrance. The drop continued down; this was
|
|
dismissed as an irrelevance but could be worth looking at, and the way on was
|
|
a loose 3m climb up into a draughting tube. It then decided to go down an
|
|
awkward climb, later laddered, and after a short grovel it opened up and
|
|
popped over the edge of a great black hole. With whoops of ecstacy the
|
|
explorers lobbed boulders over the edge and grinning listened to the
|
|
tantalising booms as they bounded into the depths. And then Ben realised he'd
|
|
have to go down and suddenly he didn't feel very well.
|
|
A retreat was made for some more tackle, and the next day saw frightening
|
|
quantities of rope ferried to the edge of the pitch. Off to the left, an
|
|
interesting crawl tempted Julian and Naomi, and they disappeared down this to
|
|
intersect a large passage leading to another set of smaller shafts partially
|
|
descended before it was decided to concentrate efforts on the big pitch.
|
|
One of the attractions of this alternative route is that the large passage
|
|
also comes back to the head of the big pitch, so the crawl could be avoided
|
|
by a spectacular Tyrolean traverse rigged across the 80m drop. Meanwhile
|
|
Ben and John were bolting down the big pitch with a series of glorious
|
|
French style freehanging rebelays. The shaft opened into a large rift, with
|
|
some black peaty mud on the walls in the upper section - no explanation
|
|
for this mud was ever found. The rift bottomed out at a small streamway
|
|
which continued with a bit of a traverse and a short drop. There had been
|
|
enough excitement for the day and so it was time to exit for an early
|
|
evening beer in the sun.
|
|
The weather turned nasty, but after a couple of days the party returned.
|
|
The gear had been scattered around the entrace to dry in the sun, and
|
|
longjohns now had to be dug out of the snow, resulting in much whimpering.
|
|
But two slightly damp cavers were soon back on the big pitch, wondering
|
|
what it would be like with the water flowing. Fortunately the rope gave a
|
|
fairly dry hang, and the descent was continued down the rift, avoiding most
|
|
of the stream with a series of short traverses and pitches before meeting
|
|
a second shaft. Here it was impossible to escape the water, and the icy
|
|
wind and spray soon penetrated the thickest longjohns. While it may be great
|
|
for the bolter at the sharp end of the rope, with much to keep him
|
|
occupied and enough exercise to stay warm, his partner squatting on a ledge
|
|
above has nothing to do but shiver and ask himself why he's there. There
|
|
was no obvious answer, and the team retreated.
|
|
Ben and John now had to go home, despite despite wanting to stay and help
|
|
derig, so Wiggy joined Julian in a final pushing trip. The final section
|
|
of the second shaft was descended and a few shorter pitches followed, before
|
|
a truly tremendous shaft was reached. The last decent length of rope (40m)
|
|
was fed down and Julian descended. The rope hangs free after the first metre,
|
|
and for most of its length hangs in the middle of a circular shaft
|
|
approximately 6m in diameter. The rope ended 3m off the floor so Wiggy sent
|
|
down a short length of rope so the descent could be completed. Beyond another
|
|
pitch estimated at 15m continued, but lack of rope precluded a descent.
|
|
Time had run out so the cave was surveyed and detackled.
|
|
Wolfehohle still has much to offer; there is no reason why it shouldn't
|
|
reach -800m. Many leads have not been explored and the pot should provide
|
|
the younger generation with fun for the next couple of years while
|
|
EXCS return to their retirement.

..astart 'Dye Testing in Chapel-Le-Dale' 'Julian Griffiths' 15
|
|
..blank 4
|
|
$bIntroduction$b
|
|
Over the course of the previous year a series of water tracing tests based
|
|
on the streams feeding the Gods Bridge resurgence in Chapel-Le-Dale have
|
|
been carried out. It was hoped that these tests might give some indication
|
|
of the potential of the diving sites in this part of the valley. The original
|
|
work in this area was carried out by members of the Yorkshire Geological
|
|
Society in the early 1900's, the results of this work being published in
|
|
Volume 15 of their Proceedings (1904). Although very comprehensive their tests
|
|
did not include Joint Hole, nor, because theirs was a study on karst water on
|
|
Ingleborough, did they cross the valley to test some of the streams sinking
|
|
on the slopes of Whernside. As access to Joint Hole has recently become easier,
|
|
Joint was an obvious candidate for testing and there was also much speculation
|
|
about a branch in Midge Hole possibly leading up to Ellerbeck Hole. The test
|
|
was fairly straight forward, or so it was thought.
|
|
..blank
|
|
$bResults$b
|
|
The results of the test have been a bit of an eye-opener. Conventional
|
|
wisdom has Meregill Hole going to Meregill Skit, Roaring Hole to Joint Hole,
|
|
Great Douk Cave and Hardrawkin Pot to Hurtle Pot and Ellerbeck Hole to
|
|
Midge Hole. Quite how the Great Douk to Hurtle myth arose is something of a
|
|
mystery as the YGS's tests indicated that Great Douk did not go via Hurtle
|
|
on its way to Gods Bridge. However, this is the route given in "Limestone
|
|
and Caves of North West England". It may have resulted from misinterpretation
|
|
of the map published in the proceedings which shown a line drawn from Great
|
|
Douk to a point $b just below $b Hurtle. In the event Hardrawkin and
|
|
probably Great Douk go to Joint. I say "probably" for Great Douk because it
|
|
hasn't been tested to Joint (there were no detectors in Joint at the time)
|
|
but it certainly doesn't go to Hurtle which leaves one with few alternatives.
|
|
Sunset Hole goes through the lower streamway in Roaring on its way to
|
|
Meregill Skit and although Meregill also goes to Meregill Skit the results
|
|
of the test were significantly different from that done by the YGS. When
|
|
they did the test Meregill Skit appears to have been a permanent resurgence
|
|
whereas now it only acts as a resurgence in very wet weather.
|
|
The dye was introduced at 1pm in the surface stream and reappeared next
|
|
morning at Meregill Skit. Next time, the dye was introduced into the stream
|
|
below Aven Entrance, but took several days to reach Meregill Skit.
|
|
Detectors removed 64 hours after the dye was introduced were negative.
|
|
There are a number of possible explanations for this.
|
|
$b(a) $b The fact that Meregill Skit no longer resurges under normal conditions
|
|
reflects a fundamental change in the course of the water underground so that
|
|
it now takes a far less direct route to its eventual resurgence.
|
|
$b(b) $b There is another outflow from the Mere which takes an entirely
|
|
separate and far shorter route to Meregill Skit. This could be proved
|
|
either way by an exact repeat of the YGS test.
|
|
$b(c) $b The dye coming out of Meregill Skit was not in fact from Meregill but was
|
|
the remnant of a previous test. The only reason for putting this alternative
|
|
foreward is that it was the reason for another of their false results,
|
|
Sunset Hole to Hardrawkin. However, I think that this is unlikely.
|
|
Whilst on the subject of Meregill Skit and Joint it is apparent from the
|
|
tests that the two connect quite close behind Gods Bridge. Tests that were
|
|
positive at Joint Hole were negative at Meregill Skit and therefore the water
|
|
in Joint does not flow through Meregill Skit on its way to Gods Bridge.
|
|
Further up the valley having "lost" the first lot of dye in Ellerbeck Hole
|
|
a second attempt with double the quantity proved that Ellerbeck goes to
|
|
Hurtle and not to Midge. It is likely to be the source of the deep route
|
|
in Hurtle though this has not been specifically tested.
|
|
Whilst this testing has solved a number of problems it has by no means
|
|
completed the work on streams feeding Gods Bridge. There remain a number of
|
|
loose ends to tie up including testing Great Douk to Joint and Ellerbeck
|
|
to the deep route in Hurtle. There is also a need to establish the watershed
|
|
on the Whernside side of the valley. Does Blake Bank Moss Cave represent
|
|
the limit of the Gods Bridge catchment area or does it extend to Dale
|
|
Barn Cave? Its a long time since we've heard anything about the trans-Craven
|
|
system!

|
$bThe Tests $b
|
|
A diary of the tests is given below. The exact location of each of the
|
|
major detector sites was as follows.
|
|
..blank
|
|
$bGods Bridge $b - Normally one in the furthest upstream of the two main
|
|
resurgences and one in the highest rising in normal conditions. In fact it
|
|
doesn't matter where the detectors are placed at this site as one of the earlier
|
|
tests established that all the risings are connected.
|
|
$bHurtle Pot $b - Bottom of entrance boulder slope going upstream, just before
|
|
passage turns left.
|
|
$bJoint Hole $b - 15m into the first sump.
|
|
$bMeregill Skit $b - 10m into bedding plane at bottom of pot heading
|
|
approximately South East.
|
|
$bMidge Hole $b - In a pool at the end of a crawl which leads off opposite to
|
|
where the entrance crawl drops into a roomier trench. This was not a very
|
|
satisfactory site as it is not clear that there is much flow in this
|
|
pool except in wet conditions.
|
|
..blank
|
|
$b12 Feb 1983 $b - Control detectors placed at Gods Bridge, Hurtle Pot and
|
|
Midge Hole. Water conditions low.
|
|
$b19 Feb 1983 $b - Control detectors removed. Water still low. All detectors
|
|
were negative.
|
|
$b12 Mar 1983 $b - Detectors placed at Gods Bridge, Midge Hole and Hurtle Pot.
|
|
3 pints of dye introduced at Ellerbeck Hole. Water conditions low.
|
|
$b19 Mar 1983 $b - Detectors retrieved from Gods Bridge, neither appeared
|
|
convincingly positive. Midge Hole was too wet to enter. The detectors in
|
|
Hurtle Pot had disappeared.
|
|
$b10 Apr 1983 $b - Detectors in Midge Hole collected. Both negative.
|
|
$b16 Apr 1983 $b - Detectors placed in Gods Bridge, Hurtle Pot and Midge Hole.
|
|
1 gallon of dye introduced at Great Douk.
|
|
$b23 Apr 1983 $b - Detectors at Gods Bridge and Hurtle Pot retrieved. Those at
|
|
Gods Bridge were positive, those at Hurtle Pot negative. Good flow of water
|
|
during test.
|
|
$b30 Apr 1983 $b - Detectors at Midge Hole retrieved. All were negative.
|
|
$b30 May 1983 $b - Detectors placed in Hurtle Pot, Joint Hole, Midge Hole,
|
|
Meregill Skit and Gods Bridge. 1 gallon of dye put down Hardrawkin the next
|
|
day. Conditions dry, but heavy rain within a day.
|
|
$b4 June 1983 $b - Detectors retrieved from all sites. Those at Joint Hole and
|
|
Gods Bridge were positive, those at Midge Hole, Meregill Skit and Hurtle Pot
|
|
were negative.
|
|
$b2 July 1983 $b - Detectors placed in Joint Hole, Gods Bridge, Meregill Skit
|
|
and the lower streamway in Roaring Hole. 1/3 to 1/2lb of Leucepher powder
|
|
introduced at Sunset Hole.
|
|
$b10 July 1983 $b - Detectors at Meregill Skit, Joint Hole, Roaring Hole and
|
|
Gods Bridge removed. Those at Roaring Hole and Meregill Skit were
|
|
faintly positive, those at Joint Hole and Gods Bridge negative. The latter
|
|
were out of the water when collected and either this or the dilution
|
|
between Meregill Skit and Gods Bridge could have accounted for the result.
|
|
$b27 Aug 1983 $b - Detectors placed in Gods Bridge, Joint Hole and Meregill
|
|
Skit. 1 gallon of dye put down Meregill Hole in the stream just below the
|
|
Aven Entrance. The Mere was full, but water in the resurgence was very low.
|
|
$b30 Aug 1983 $b - Detectors retrieved from Gods Bridge, Joint Hole and Meregill
|
|
Skit 64 hours after dye was introduced. All were negative. This contrasts
|
|
with the YGS test which came through in a day.
|
|
$b25 Sep 1983 $b - Rest of detectors retrieved from Gods Bridge, Joint Hole
|
|
and Meregill Skit. Those at Gods Bridge and Meregill Skit were positive,
|
|
Joint Hole negative. Heavy rain in the intervening period.
|
|
$b4 Mar 1984 $b - Detectors placed in Joint Hole (in 3rd sump), Hurtle Pot
|
|
and Gods Bridge. 1 gallon of dye introduced at Ellerbeck Hole.
|
|
$b18 Mar 1984 $b - Retrieved detectors from Gods Bridge, these were positive.
|
|
$b25 Mar 1984 $b - Removed detectors from Hurtle Pot. These were positive. Good
|
|
flow of water during the test.
|
|
..blank
|
|
$bMethod $b
|
|
The method $bwas $b basically that outlined in the Yorkshire Subterranean Journal
|
|
No. 2 pp46-49. Cotton wool was placed in small plastic bags which had had
|
|
holes punched in them with a normal handpunch. These were tied on to diver's
|
|
"Snoopy Loops" (loops of inner tube with a loop of diving line attached) and
|
|
the Snoopy Loops wrapped around a convenient boulder. Where possible the
|
|
bags were covered with other boulders. These detectors proved extremely
|
|
robust, the only ones that were lost weren't placed by me and I suspect that
|
|
they were incorrectly placed. If the site was poorly supplied with boulders
|
|
(such as Meregill Skit) the bags were attached to a diver's lead weight; this
|
|
seemed to work equally well.
|
|
Originally stockings were used in preference to plastic bags. This was
|
|
stopped though when a control detector left in a bowl of water for a week
|
|
developed a thin fluorescent film on it. This despite that fact that the
|
|
stocking showed no obvious signs of fluorescence when tested under UV light
|
|
prior to the construction of the detector. A similar wad of cotton wool in
|
|
a plastic bag showed no fluorescence. All the tests outlined in this article
|
|
were done with plastic bags.
|
|
To try to minimise the possibility of contamination the detectors were
|
|
inspected under a UV lamp prior to placing and, wherever possible, the dye
|
|
and the detectors were handled by two different people. Two detectors
|
|
were placed at each location. When one of these was removed for testing
|
|
it was replaced by another detector. On the tests that were positive this was
|
|
a useful check on whether all the dye had flowed through or whether the

|
site was still contaminated.
|
|
Generally positive results were unmistakable with large fluorescent blotches
|
|
round the holes in the bags. The dye did not penetrate very far into the
|
|
cotton wool so there is a danger of the flourescence being hidden by dirt
|
|
if the detector was left in too long. Few detectors were left in for more
|
|
than a month for this reason. The only poor result was from the one at
|
|
Roaring Hole where Leucepher powder was used. A solution seems to be the best
|
|
way of introducing the dye. The dye used for the rest of the tests was
|
|
Photine CS dissolved in Diethyl Glycol Monoethanolamine and water E=90.

Three weeks after returning from Austria I was back across the Channel, this
|
|
time en route for the Moravian Karst in Czechoslovakia. There is a certain
|
|
mystique about an area such as Moravia, in my mind it was a close relative
|
|
of Transylvania. I had vision of a mountainous region, dotted with lofty
|
|
castles and inhabited by Count Dracula look alikes. As it happened it was not
|
|
unlike Mendip and not even the wildest imagination could mistake the beer
|
|
lust of the local inhabitants for blood lust. The nearest thing that approached
|
|
it was some villagers sat in a local bar watching a CSSR v. USSR ice hockey
|
|
match on the TV.
|
|
Close inspection of my road map of Europe revealed that Moravia is only about
|
|
100 miles north of Vienna. It is close to Brno, famed for the Bren gun and the
|
|
fact that nearly every army in Europe has trampled on it at some stage. The
|
|
site of the battle of the three armies, Austerlitz, is nearby. Here Napoleon
|
|
saw off the combined armies of Russia and Austria. The region's similarities with
|
|
Mendip are that it is gently rolling countryside, reaching no great height,
|
|
but incised by two large gorges. It must be said that this is as far as the
|
|
similarities go. The caves are typically very large old phreatic systems, the
|
|
largest of which, the Amertska Jeskyne, is nearly 40km long.
|
|
Being an official camp all the delegates were put up at a local hotel. I was
|
|
lucky to share a room with the only other English speaking person there,
|
|
Tom Iliffe of Bermuda. Also sharing the room was one of the local
|
|
Czechoslovakian cavers, a friendly chap who kept what could only be described
|
|
as a bottle of clear methylated spirits under his bed. This he would offer to
|
|
anyone who happened to come into the room. Prolonged exposure to it was
|
|
ruinous and so visits to the room had to be timed very carefully. Lectures
|
|
took up the first two days. A translation service was provided, but where
|
|
someone was lecturing in a language other than Czech the lecture was translated
|
|
into Czech first and then relayed to the other translators to translate into
|
|
other languages. This somewhat delayed the impact of the speech on the audience
|
|
and it was unnerving to find the audience laughing at a joke you'd told five
|
|
minutes ago.
|
|
The formalities of lectures over the diving commenced. Just to make sure we
|
|
could all dive we were taken to a local reservoir where visibility and
|
|
shallow depth was assured. A little while later, sat in a pool of liquid mud
|
|
at -45ft, I began to doubt their claims. The appearance of my side mounted
|
|
tanks with no buoyancy compensator was greeted with something akin to mass
|
|
hysteria by the assembled divers. There was much jostling for place to get
|
|
a photograph of the weird and threatened beast before they moved in for a
|
|
closer inspection.
|
|
The first proper cave dive was in the Amertska Jeskyne, a cave that runs in the
|
|
hills alongside one of the deep gorges. How nice to be able to walk to the
|
|
diving site in dry grots with your gear in a rucksack on your back, to change
|
|
into drysuit at the sump. Not that carrying gear was compulsory for the divers
|
|
as the Czech organiser had provided any number of sherpas. Brief pause for
|
|
photographs for the local paper and then off into the beautiful, crystal clear
|
|
phreatic tube. This continued for 300m until it opened out in the roof of a
|
|
large chamber. Below the chamber dropped away to -30m and more and the
|
|
continuing passage has not been pushed by the Czechs. The sump which is fed by
|
|
percolation water heads away from the gorge at right angles to the main system.
|
|
It could be a long dive. Afterwards we walked up to the 180m open air shaft
|
|
of the Macocha Chasm which drops into the Puuka river, the downstream
|
|
connection and eventual resurgence of the Amertska Jeskyne.
|
|
Thinking that I might be feeling a little homesick the Czechs said that they
|
|
had a good British sump lined up for me the next day. This was in the Barova
|
|
Jeskyne, a cave close to the resurgences in the other gorge. Upstream was
|
|
supposed to lead through to the Byci Skala though no-one had pushed it. Beyond
|
|
this there is considerable potential up towards the system's sinks, but
|
|
unfortunately the upstream sump in the Byci Skala is choked. The carry into
|
|
the Barova Jeskyen was typically Czechoslovakian, ie. easy. The Czech diver
|
|
with me explained that we would have to use hand signals in the sump, not the
|
|
BSAC ones I was accustomed to, but something that approximated to bottom
|
|
pinching. The significance of this became apparent when we turned to come
|
|
back in the second sump having decided that digging would be required to make
|
|
any further progress. The mud was so thick that I couldn't see my diving
|
|
partner. Hence a quick couple of pinches rectified the position and it was an
|
|
appalling dive back. The Byci Skala is close by so we went for a tourist trip.
|
|
It is a very impressive cave and steeped in history. A medieval lord who had
|
|
died nearby whilst on a caravan was buried with all his entourage in a rock
|
|
shelter near the entrance, such was the fashion in those days. About 400m
|
|
inside the entrance a plaque announces that Marie Theresa was there. She didn't
|
|
have to use her own carbide, the full length of the cave being lit by torches.
|
|
In the second world war the cave was used as a munitions factory and several
|
|
years after the war a German officer was found hanging in one of the chambers
|
|
near the entrance. Most of the cave consists of long phreatic passage and there
|
|
is a long canal section in the middle for which we used a boat. The whole lot
|
|
didn't take more than a couple of hours to complete.
|
|
The final day was to a be a dive through to the Amertsha Jeskyne from the
|
|
Macocha Chasm, a dive of 400m. Unfortunately the visibility was too poor to
|
|
enable the line to be laid from where it finished about 220m in so we had
|
|
to content ourselves with a dive to that point and back.
|
|
In between the diving the Czechs entertained us royally. Beer at 20p a pint
|
|
oiled the cogs of international communication and their plum brandy left you
|
|
with something to remember it by the next morning. A very fine week's caving.

India is not a land renowned for its sporting caves and pot-holes. In fact the
|
|
large desolate basalt plains of the Deccan plateau can hardly be considered
|
|
fruitful territory for speleologists. Nonetheless this area boasts some of
|
|
the finest decorated cave temples in the World. The secret, of course, is that
|
|
the temples were carved out of the reasonably soft volcanic rock of the region.
|
|
Some of the temples are hardly caves, one of the finest is a complete building
|
|
with walls and roof carved out of a cliff-side and a total floor area greater
|
|
than that of the Parthenon in Athens. Most are of a more modest size and are
|
|
tunnelled into the side of the hills. The two most famous sites are conveniently
|
|
near each other close to the town of Aurangabad in Maharashtra state about
|
|
200 miles from Bombay. These are the Ellora caves which are decorated with fine
|
|
sculptures and the Ajanta caves which are the more famous on account of the well
|
|
preserved wall paintings.
|
|
India has a healthy tourist industry and one can get to the caves by tour or
|
|
local bus from Aurangabad. Aurangabad is well connected by train and air to
|
|
the rest of India because of the caves. They are certainly one of the sites
|
|
any self respecting tourists would wish to include on their itinerary.
|
|
The caves at Ajanta were the first to be made, they are all Buddhist and date
|
|
from about 200 BC to 650 AD. There are 29 caves in all, 24 monasteries or
|
|
Viharas and 5 temples or Chaityas. The caves are cut into the sides of a steep
|
|
river valley in a densely forested region. They were discovered purely by
|
|
chance in 1819 by an English hunting party out after tigers. Typically they were
|
|
very badly damaged after their discovery both by graffitists and the warm humid
|
|
air which entered when they were opened. This is especially unfortunate because
|
|
of the exceptionally beautiful wall paintings found inside some of the caves.
|
|
However in the 1920s two leading Italian art restorers were brought over and
|
|
after long an painstaking work some of the former glory was recaptured.
|
|
Access to the caves is limited because of their fragility and lighting is dim
|
|
and only on when tour parties are inside. Despite this the paintings are
|
|
magnificent.
|
|
The caves were constructed by driving in a series of horizontal adits, these
|
|
were then connected by cross passages thus leaving the roof supported on
|
|
pillars of rock. These pillars were often carved, in fact all statues in the
|
|
caves were carved from the rock in situ.
|
|
The caves at Ellora are more renowned for their carvings. Ellora also has a
|
|
mixture of religions represented in its caves, there are 34 caves; 12 Buddhist,
|
|
17 Hindu and 5 Jain. The Buddhist caves are smaller and more subdued than their
|
|
Ajanta counterparts. They were all built after the caves at Ajanta between
|
|
600 AD and 800 AD during a period of relative Buddhist decline, all but one
|
|
are Viharas. The Hindu caves are the most famous at Ellora because of the
|
|
profusion of wall carvings, they were built around 900 AD but the earliest were
|
|
probably built when the later Buddhist caves were being finished because of
|
|
similarities in decoration. All these caves are temples, the most famous being
|
|
the enormous Kailassa temple. This is dedicated to Shiva and has been in
|
|
practically continuous use since it was built. Over 200,000 tons of rock were
|
|
removed and the whole edifice was carved from the top down so requiring no
|
|
scaffolding. Finally, a few hundred metres away from the main site are the
|
|
Jain caves, these are similar to the Buddhist caves in design but are covered
|
|
in carvings of a very fine detail. The Jain caves were the last to be built on the
|
|
site and date from 800 AD to 1000 AD.
|
|
India has other cave temples at various other sites, mostly in Maharashtra,
|
|
but none of the others compare to the well preserved examples of Ellora and Ajanta.
|
|
If a caver visits the sub-continent, he can visit these sites and at least
|
|
claim to have been underground. As well as this benefit of being able to tick off
|
|
another country the caves are well worth a visit on artistic merit alone.

Well, here we are again, another year later and another later journal.
|
|
Editorials should be like mini-skirts, long enough to be decent but short
|
|
enough to maintain interest, so.....
|
|
I'd like to thank everbody who wrote articles and helped with the production
|
|
of the journal, and encourage anyone who might feel like doing so in the
|
|
future. Thanks especially to Becky who proof read it, because my spelling
|
|
is awful.
|
|
Any comments, slanders or libels should not be directed to me, but to next
|
|
year's editor, Nick Hawks, c/o James Hickson, address below. Preferably you
|
|
could inundate him with articles.
|
|
Since I had no entries for the quiz in last year's journal, the prize, which
|
|
was to have been a case of Champaigne, will have to remain in my possession.
|
|
The answers are to be found elsewhere in this edition.
|
|
Finally, apologies for the late publication this year, but a certain critical
|
|
article which shall remain nameless only arrived two days before departure
|
|
for Austria. The only consolation is the Austria '84 Stop Press.
|
|
OK, thats it, off we go.....

The square shaped entrance lies just below (22m vertically at 34m on a bearing
|
|
of 158$+o$l) the nipple at the end of the ridge running SSW from the Vd.
|
|
Schwarzmoos Kogel. The first pitch starts after a short climb down boulders,
|
|
from here light may be seen entering from another entrance, 143b. The pitch
|
|
(20m) lands on a small ledge and a short free climb leads to a traverse over
|
|
wedged blocks. The next pitch (10m) is rigged over the edge of the last
|
|
of these and brings one to a balcony at the start of a 23m shaft. Another clean,
|
|
almost circular shaft (19m) follows, to a climb (6m) down wedged boulders.
|
|
The passage now narrows to a small vadose canyon with a stream in it, but soon
|
|
turns verticle at an 8m pitch, quickly followed by one of 18m. At the foot of
|
|
this final shaft the stream flows down a rift, approximately 10m deep, but
|
|
too narrow to follow, the draft blowing inwards.

Austria last year was plagued by bad weather. Promises of fierce Alpine
|
|
sunshine did not materialise as a damper was put on the proceedings.
|
|
Nevertheless, much prospecting was done, numerous holes were found, and this
|
|
year's expedition can look foreward to two holes wide open at 270m and
|
|
200m, and the prospect of linking the Stellerweghohle system to a higher
|
|
entrance increasing its depth to 990m.
|
|
Back in Cambridge the Club year got off to a good start. The squash went well,
|
|
or so we thought, probably mainly due to the catering arrangements. The coach
|
|
trip to Carlswalk succeeded in getting 45 freshers cold, wet, muddy and either
|
|
jubilant or miserable in two waves and record time. This, combined with our
|
|
quick persuasive tongues and charming manners produced a large number of
|
|
new members.
|
|
As seems to happen every year the departure of a number of the clubs oldest
|
|
and most experienced members at the end of the year left the club with only
|
|
a handful of cavers capable of leading trips. Fortunately those who did remain
|
|
did come on meets and did take novices caving. We saw a few years ago what
|
|
happens when the experienced cavers form a clique and leave the novices
|
|
to their own devices. Luckily this was avoided. The lack of experience at the
|
|
beginning of the year poses a perenial problem with much concern being
|
|
expressed over what will happen next year. I can see no solution to this
|
|
problem. The idea of recruiting a large number of members at the beginning of
|
|
the year to provide the next year with experience just doesn't work. Most
|
|
people don't like caving and nothing you can do will make them. You're stuck
|
|
with the fact that only a small number of people will stay with the club and
|
|
gain the necessary experience. This year, therefore, thanks to those who
|
|
did remain to lead novice trips. Caving has gone on as normal with a full
|
|
minibus hurtling up to the Dales every fortnight during term.
|
|
These term time trips have been well attended by new members and the caving
|
|
has been more oriented towards the novice. It also became possible to hire
|
|
cheaper minibusses as we had a driver over 23; this, with the travel subsidy
|
|
provided by the Societies Syndicate, brought the cost of travel and
|
|
accomodation down to below ten pounds for the weekend.
|
|
Vacation meets have become quiet affairs attended mainly by experienced cavers
|
|
who are then free to do their own thing.
|
|
Socially the club is as active as ever. The Wednesday night pub meet in the
|
|
Granta became the club's focal point. Nearly all the active resident members
|
|
descend on the Granta much to the delight of the charming Landlord and
|
|
Landlady. The other weekly pub meets still occur though are slightly less
|
|
well attended, and Tuesday lunches are still popular. Numerous parties have
|
|
been thrown, some exceptionally good, some awfull. The dinner came and went
|
|
bringing with it the traditional debagging of the president, and the
|
|
soon-to-be-traditional secretarial streak. The dinner also incurred the wrath
|
|
of the college authorities who showed their displeasure in a material fashion.
|
|
We will return to Austria this summer mainly by default. CUCC has had summer
|
|
expeditions to Austria for the past 8 years now. This year interest was
|
|
expressed in going somewhere else, preferably more 'exotic'. Austria requires
|
|
little organisation and since no-one was willing to do the work necessary to
|
|
go elsewhere, we are returning there.
|
|
Finally I would like to thank everone who has helped in the running of the
|
|
club over the past year, and wish the committee the best of luck for the
|
|
coming year.

Since the journal is so late this year, here's a brief report on CUCC's
|
|
latest activities.
|
|
Steinschlagschacht bottomed at about 240m, with the rift suddenly becoming
|
|
to narrow to follow. Due to lack of enthusiasm it was not surveyed below
|
|
last year's limit. Wolfehohle also stopped, at a sump, just after 400m, but
|
|
was surveyed. The Wolf, it seems, is actually a Bear of some description.
|
|
We can now look foreward to a period of mindless recrimination while the
|
|
name is haggled over.
|
|
The attempt to connect into the Stellerweghohle system from above (entrances
|
|
143 and 144) yield an audible connection, in one direction at least, but is
|
|
too long to be hammered open.
|
|
Some prospecting was done on the plateau, heading towards the Ht. Schwarzmoos
|
|
Kgl., which is getting a depressingly long way from the Car Park. Maybe future
|
|
expeditions will have to camp on the plateau.
|
|
Apart from that, it rained rather a lot. The beer tent was decorated with
|
|
sweetcorn by the simple expedient of heating a can until it exploded. Some
|
|
boy scouts subsequently asked us not to let off fireworks in the middle of
|
|
the night. The Landlady at the Staudnwirt also indicated that Meatloaf et. al.
|
|
at full blast tended to drown out the musak in the bar. Still, it was
|
|
discovered that it is possible to have a drunken bop for 4 people
|
|
in the back of a small Land Rover while doing 50 mph. along the road to
|
|
Grindlesee at 3 in the morning.
|
|
See next years journal for the full sordid details!

|
|
..blank 4
|
|
|
|
The 1623/142 entrance lies in thick pine-scrub above the Stogerweg (path 201)
|
|
roughly halfway between Windloch (132) and Stellerweghohle (41). It takes about
|
|
ten minutes to climb/fight/thrash through the bunde to get to it from the path.
|
|
The entrance is labelled "P132" in red paint because the 1982 expedition
|
|
used cave numbers which had been allocated to a german team, thus caves
|
|
described in "Cambridge Underground 1983" as 131 and 132 have been renamed as
|
|
141 and 142. Cave 142 is the one with the Big Chamber in it, "half the size
|
|
of Gaping Gill" according to last years' grade 1 survey, in fact it is
|
|
about 90m by 30m, and 40m high.
|
|
|
|
142 was originally explored by Phil Townsend, Doug Florence and Mike Thomas
|
|
in 1982, and almost caused Mike and Doug to call out a rescue for each other
|
|
when they got seperated in its intestinal complexities. This year Wiggie
|
|
found a 20m pitch near the entrance which he almost lobbed off (which didn't
|
|
go anywhere). Gail and Philip had great difficulty finding the Big Chamber
|
|
(3rd time lucky) but found a dripping shaft with caravan-sized jammed boulders
|
|
in it instead. This was later pushed by Julian and pronounced to be very
|
|
reminiscent of the German Series in Stellerweg (41),but smaller and more
|
|
miserable. Later that same trip Julian, with Philip and Naomi, found the
|
|
connection with 41 along the Rodent Runway; named after a nondescript
|
|
skeleton with big teeth found in the connection chamber at the bottom of the
|
|
first pitch in 41. This party had set out to find the connection but had
|
|
given up after pushing innumerable 45 degree rifts to their conclusions and
|
|
were looking for a pitch-less way to the Big Chamber when they found themselves
|
|
standing in Stellerweg.
|
|
|
|
Apart from the entrance grovel, a few active drips, the shaft pushed by
|
|
Julian and the Big Chamber, the entire 142 system is a dusty, abandoned series of
|
|
hading chambers formed phreatically on a set of joints at 45$+o$l# to the
|
|
horizontal, parallel to the very similar Stellerweghohle entrance series. The
|
|
joints run almost precisely NE-SW and are tilted such that the chambers all
|
|
slope down to the SE. The bedding is not obvious in the cave, but in two
|
|
widely-separated locations it also appeared to lie at 45$+o$l# to the horizontal,
|
|
but at right angles to the joints such that it dipped to the NW. Surface
|
|
features in the area of the caves, the south end of the Schwatzmooskogel,
|
|
supported this observation.
|
|
|
|
Traversing across the tops of the 45$+o$l# ramps was generally easier in 142
|
|
than in 41 and so this new discovery provides a slightly easier way in to
|
|
this part of the Stellerweghohle-Schnellzughohlensystem. (However it is
|
|
extremely dry and dusty and cannot be recommended for contact lens wearers.)
|
|
The chamber where the routes to the Big Chamber and the connection
|
|
diverge was pretty thoroughly investigated, as were all the leads from
|
|
there back to Wiggie's pitch near the entrance, but there are lots of
|
|
leads in the Rodent Runway itself that have not been followed and the
|
|
ways out of the Big Chamber have not all been entirely exhausted. There
|
|
is plenty of scope for more discovery in this cave which is not only close
|
|
to the path, but requires very little tackle.

|
|
At the end of the 1982 exploration it was thought that 141 (aka 131)
|
|
would connect with the 41-115 system. The 1983 expedition actually
|
|
connected 142 instead, 141 being found to be get too small quite
|
|
rapidly. This connection is not a very significant discovery and has
|
|
added nothing to the depth of the system. However, the perched phreatic
|
|
tube found in 144 by Pete and Chas is a very much more interesting
|
|
possibility: it is at the same altitude as the Big Chamber in 142 and
|
|
the confused series of passages at the head of the Big Pitch in 41
|
|
(see area survey), and is only 150m away from either of these horizontally.
|
|
If we could push a connection to 144 next year from the 41-142 leads
|
|
we would not only add 74m to the total depth of the system (making a possible
|
|
total of 972m) but we would have found our own highest entrance to the system
|
|
so that it would become a CUCC/EXCS discovery from top to bottom. In
|
|
these circumstances we should perhaps take care with the name we give to
|
|
144, we couldn't have our biggest and best discovery go down in history
|
|
under its interim desciption: "Tonys-secondhohlen-system"!

..astart "Draft EEC Caving Regulations" "Anon" 33
|
|
..blank 4
|
|
It has come to our notice that caves do not fulfil the EEC aim of
|
|
standardisation throughout the community, and that they are generally in
|
|
contravention of EEC Health and Safety Regulations (H&SR). We have therefore
|
|
drawn up a standard for caves that will be enforced by new legislation.
|
|
..blank
|
|
$b Size $b
|
|
This raises questions of both length and depth. Many caves pose unacceptable
|
|
strains on the stamina of cavers, and the general aim here is to shorten
|
|
all caves to an acceptable size. Many will also need enlarging, the
|
|
Commission feeling that the "squeezes" and "crawls" that are found
|
|
underground are too dangerous.
|
|
As a general rule all cave passages will be large enough as to permit the
|
|
passage of a beach-ball of 2m diameter. This will, we feel, help to reduce
|
|
the incidence of both back-ache and abrasion of elbows and knees among cavers,
|
|
bringing the sport into line with the H&SR.
|
|
There are also many caves that are too deep. Pitches are another
|
|
unacceptable hazard, and must therefore be brought under careful control. We
|
|
propose two alternative systems.
|
|
a) For larger caves, a chair-lift system. These will be operated in accordance
|
|
with safety regulations similar to those used in mountainous regions.
|
|
b) For smaller caves, pitches will be eliminated and slopes with an angle not
|
|
exceeding 45$+o$l# instituted. These slopes will have numerous holds within
|
|
them, and will not exceed 7m in length. Professional staff will be employed to
|
|
supervise their use, and to ensure that the slopes are kept clean and dry.
|
|
Lifelining will be compulsory, and performed by the above staff.
|
|
Concerning the lengths of caves, we feel that no caver should cave for more
|
|
than 4 hours without rest. This leads us to the provision of facilities
|
|
within caves.
|
|
..blank
|
|
$b Facilities $b
|
|
These are currently in a deplorable state. Refreshment is normally limited to
|
|
a soggy chocolate bar, while there are no provisions for rest or recovery after
|
|
or during strenuous exercise. This state of affairs cannot be allowed to
|
|
continue. The commission therefore proposes the following changes.
|
|
a) Rest stations. These will consist of warm and comfortable cafes, with
|
|
showers and rapid drying rooms attached. Warm, non-alcoholic, beverages will be
|
|
served, as will hot food, reaonable prices being gaurenteed by an EEC subsidy.
|
|
Stops at rest stations will be compulsory, to prevent cavers reaching
|
|
dangerous states of exhaustion and exposure.
|
|
b) Communications. This is another area which has led to accidents in the past.
|
|
Thus, emergency telephones will be installed at 100m intervals within the
|
|
cave to prevent cavers becoming lost. They will be clearly signposted, and
|
|
a map of the cave will be posted by each telephone showing its position.
|
|
c) Lighting. This is currently the most urgent problem. The current lighting
|
|
in caves is appalling, falling below the most lax H&SR requirements.
|
|
Natural lighting is virtually non-existant, while personal lighting is
|
|
often minimal and unreliable. We therefore propose to install low-power
|
|
lighting throughout the cave, with high-powered lighting at all awkward and
|
|
potentially dangerous places. Back-up generators will be installed in case of
|
|
power failure.
|
|
We now consider the question of equipment used by cavers.
|
|
..blank
|
|
$b Personal Equipment $b
|
|
This is often dangerously varied and of questionable reliability. We therefore
|
|
feel it necessary to impose certain guidelines.
|
|
a) Clothing. The existing wetsuit is barely adequate given that its method
|
|
of operation requires the wearer to be wet. This must therefore be replaced by a
|
|
drysuit with a portable temperature control unit. Full-face helmets complete
|
|
with visors will also we worn to avoid accidental injury on any remaining
|
|
rock prejections. The existing harnesses are in the main inadequate, but in
|
|
future two will have to be worn in case a failure.
|
|
b) Ropes and Ladders. Ropes are seen by the commission as being among the
|
|
most dangerous pieces or equipment used, especially when employed in the
|
|
"SRT" mode. In future, any remaining "SRT" pitches will be done with a lifeline,
|
|
although given the changes outlined above we can see both ladders and ropes
|
|
ceasing to become important.
|
|
..blank
|
|
$b Temperature and Water Levels $b
|
|
The question of H&SR also raises the issue of cave temperature and water
|
|
levels. Many caves are dangerously prone to flooding, so that streamways will
|
|
need diversion into reservoirs separate from the main body of the cave. From
|
|
here the water can be heated to a suitable temperature and released back
|
|
into the streamway at a safe, controlled rate. These provisions will both
|
|
raise safety standards and increase comfort.
|
|
..blank
|
|
$b Conclusions $b
|
|
This report outlines the standards to which member countries will, in future,
|
|
be expected to conform with regards to caves. The commission realises that
|
|
reaching these standards may well prove costly, and has several suggestions
|
|
to make.
|
|
a) All real caves should be sealed and new ones created by roofing over
|
|
derelict quaries, the new cave being constructed of strong but lighweight
|
|
synthetic materials. This would have the added advantage of
|
|
reducing the danger in the event of the cave collapsing due to unforseen
|
|
stresses.
|
|
b) Local caving councils should apply for EEC Rural Development Grants.
|
|
Another source of grant income could be CAP-aided mushroom production. Either
|
|
request should prove fruitful.
|
|
c) Part of the cost of re-modelling existing caves could be met by offering a
|
|
section of the cave as a storage area for EEC agricultural products; however,
|
|
any attempt to store wine surpluses by circulating them through streamway
|
|
networks will be opposed and funds not granted or withheld.
|
|
d) A final source of grant aid may be found by clubs appealing for EEC
|
|
funds for the assistance of ethnic minorities, the current rather exotic
|
|
clothing and quaint rituals of cavers almost guaranteeing a sympathetic hearing.
|
|
Hopefully this memorandum has made clear the impending changes in speleology.
|
|
We at the commission feel sure that all cavers will join with us in seeing
|
|
these new standards as a major advance, and will therefore hasten to
|
|
implement them.

$bIntroduction$b
|
|
Over the course of the previous year a series of water tracing tests based
|
|
on the streams feeding the Gods Bridge resurgence in Chapel-Le-Dale have
|
|
been carried out. It was hoped that these tests might give some indication
|
|
of the potential of the diving sites in this part of the valley. The original
|
|
work in this area was carried out by members of the Yorkshire Geological
|
|
Society in the early 1900's, the results of this work being published in
|
|
Volume 15 of their Proceedings (1904). Although very comprehensive their tests
|
|
did not include Joint Hole, nor, because theirs was a study on karst water on
|
|
Ingleborough, did they cross the valley to test some of the streams sinking
|
|
on the slopes of Whernside. As access to Joint Hole has recently become easier,
|
|
Joint was an obvious candidate for testing and there was also much speculation
|
|
about a branch in Midge Hole possibly leading up to Ellerbeck Hole. The test
|
|
was fairly straight forward, or so it was thought.
|
|
..blank
|
|
$bResults$b
|
|
The results of the test have been a bit of an eye-opener. Conventional
|
|
wisdom has Meregill Hole going to Meregill Skit, Roaring Hole to Joint Hole,
|
|
Great Douk Cave and Hardrawkin Pot to Hurtle Pot and Ellerbeck Hole to
|
|
Midge Hole. Quite how the Great Douk to Hurtle myth arose is something of a
|
|
mystery as the YGS's tests indicated that Great Douk did not go via Hurtle
|
|
on its way to Gods Bridge. However, this is the route given in "Limestone
|
|
and Caves of North West England". It may have resulted from misinterpretation
|
|
of the map published in the proceedings which shown a line drawn from Great
|
|
Douk to a point $b just below $b Hurtle. In the event Hardrawkin and
|
|
probably Great Douk go to Joint. I say "probably" for Great Douk because it
|
|
hasn't been tested to Joint (there were no detectors in Joint at the time)
|
|
but it certainly doesn't go to Hurtle which leaves one with few alternatives.
|
|
Sunset Hole goes through the lower streamway in Roaring on its way to
|
|
Meregill Skit and although Meregill also goes to Meregill Skit the results
|
|
of the test were significantly different from that done by the YGS. When
|
|
they did the test Meregill Skit appears to have been a permanent resurgence
|
|
whereas now it only acts as a resurgence in very wet weather.
|
|
The dye was introduced at 1pm in the surface stream and reappeared next
|
|
morning at Meregill Skit. Next time, the dye was introduced into the stream
|
|
below Aven Entrance, but took several days to reach Meregill Skit.
|
|
Detectors removed 64 hours after the dye was introduced were negative.
|
|
There are a number of possible explanations for this.
|
|
$b(a) $b The fact that Meregill Skit no longer resurges under normal conditions
|
|
reflects a fundamental change in the course of the water underground so that
|
|
it now takes a far less direct route to its eventual resurgence.
|
|
$b(b) $b There is another outflow from the Mere which takes an entirely
|
|
separate and far shorter route to Meregill Skit. This could be proved
|
|
either way by an exact repeat of the YGS test.
|
|
$b(c) $b The dye coming out of Meregill Skit was not in fact from Meregill but was
|
|
the remnant of a previous test. The only reason for putting this alternative
|
|
foreward is that it was the reason for another of their false results,
|
|
Sunset Hole to Hardrawkin. However, I think that this is unlikely.
|
|
Whilst on the subject of Meregill Skit and Joint it is apparent from the
|
|
tests that the two connect quite close behind Gods Bridge. Tests that were
|
|
positive at Joint Hole were negative at Meregill Skit and therefore the water
|
|
in Joint does not flow through Meregill Skit on its way to Gods Bridge.
|
|
Further up the valley having "lost" the first lot of dye in Ellerbeck Hole
|
|
a second attempt with double the quantity proved that Ellerbeck goes to
|
|
Hurtle and not to Midge. It is likely to be the source of the deep route
|
|
in Hurtle though this has not been specifically tested.
|
|
Whilst this testing has solved a number of problems it has by no means
|
|
completed the work on streams feeding Gods Bridge. There remain a number of
|
|
loose ends to tie up including testing Great Douk to Joint and Ellerbeck
|
|
to the deep route in Hurtle. There is also a need to establish the watershed
|
|
on the Whernside side of the valley. Does Blake Bank Moss Cave represent
|
|
the limit of the Gods Bridge catchment area or does it extend to Dale
|
|
Barn Cave? Its a long time since we've heard anything about the trans-Craven
|
|
system!

$bThe Tests $b
|
|
A diary of the tests is given below. The exact location of each of the
|
|
major detector sites was as follows.
|
|
..blank
|
|
$bGods Bridge $b - Normally one in the furthest upstream of the two main
|
|
resurgences and one in the highest rising in normal conditions. In fact it
|
|
doesn't matter where the detectors are placed at this site as one of the earlier
|
|
tests established that all the risings are connected.
|
|
$bHurtle Pot $b - Bottom of entrance boulder slope going upstream, just before
|
|
passage turns left.
|
|
$bJoint Hole $b - 15m into the first sump.
|
|
$bMeregill Skit $b - 10m into bedding plane at bottom of pot heading
|
|
approximately South East.
|
|
$bMidge Hole $b - In a pool at the end of a crawl which leads off opposite to
|
|
where the entrance crawl drops into a roomier trench. This was not a very
|
|
satisfactory site as it is not clear that there is much flow in this
|
|
pool except in wet conditions.
|
|
..blank
|
|
$b12 Feb 1983 $b - Control detectors placed at Gods Bridge, Hurtle Pot and
|
|
Midge Hole. Water conditions low.
|
|
$b19 Feb 1983 $b - Control detectors removed. Water still low. All detectors
|
|
were negative.
|
|
$b12 Mar 1983 $b - Detectors placed at Gods Bridge, Midge Hole and Hurtle Pot.
|
|
3 pints of dye introduced at Ellerbeck Hole. Water conditions low.
|
|
$b19 Mar 1983 $b - Detectors retrieved from Gods Bridge, neither appeared
|
|
convincingly positive. Midge Hole was too wet to enter. The detectors in
|
|
Hurtle Pot had disappeared.
|
|
$b10 Apr 1983 $b - Detectors in Midge Hole collected. Both negative.
|
|
$b16 Apr 1983 $b - Detectors placed in Gods Bridge, Hurtle Pot and Midge Hole.
|
|
1 gallon of dye introduced at Great Douk.
|
|
$b23 Apr 1983 $b - Detectors at Gods Bridge and Hurtle Pot retrieved. Those at
|
|
Gods Bridge were positive, those at Hurtle Pot negative. Good flow of water
|
|
during test.
|
|
$b30 Apr 1983 $b - Detectors at Midge Hole retrieved. All were negative.
|
|
$b30 May 1983 $b - Detectors placed in Hurtle Pot, Joint Hole, Midge Hole,
|
|
Meregill Skit and Gods Bridge. 1 gallon of dye put down Hardrawkin the next
|
|
day. Conditions dry, but heavy rain within a day.
|
|
$b4 June 1983 $b - Detectors retrieved from all sites. Those at Joint Hole and
|
|
Gods Bridge were positive, those at Midge Hole, Meregill Skit and Hurtle Pot
|
|
were negative.
|
|
$b2 July 1983 $b - Detectors placed in Joint Hole, Gods Bridge, Meregill Skit
|
|
and the lower streamway in Roaring Hole. 1/3 to 1/2lb of Leucepher powder
|
|
introduced at Sunset Hole.
|
|
$b10 July 1983 $b - Detectors at Meregill Skit, Joint Hole, Roaring Hole and
|
|
Gods Bridge removed. Those at Roaring Hole and Meregill Skit were
|
|
faintly positive, those at Joint Hole and Gods Bridge negative. The latter
|
|
were out of the water when collected and either this or the dilution
|
|
between Meregill Skit and Gods Bridge could have accounted for the result.
|
|
$b27 Aug 1983 $b - Detectors placed in Gods Bridge, Joint Hole and Meregill
|
|
Skit. 1 gallon of dye put down Meregill Hole in the stream just below the
|
|
Aven Entrance. The Mere was full, but water in the resurgence was very low.
|
|
$b30 Aug 1983 $b - Detectors retrieved from Gods Bridge, Joint Hole and Meregill
|
|
Skit 64 hours after dye was introduced. All were negative. This contrasts
|
|
with the YGS test which came through in a day.
|
|
$b25 Sep 1983 $b - Rest of detectors retrieved from Gods Bridge, Joint Hole
|
|
and Meregill Skit. Those at Gods Bridge and Meregill Skit were positive,
|
|
Joint Hole negative. Heavy rain in the intervening period.
|
|
$b4 Mar 1984 $b - Detectors placed in Joint Hole (in 3rd sump), Hurtle Pot
|
|
and Gods Bridge. 1 gallon of dye introduced at Ellerbeck Hole.
|
|
$b18 Mar 1984 $b - Retrieved detectors from Gods Bridge, these were positive.
|
|
$b25 Mar 1984 $b - Removed detectors from Hurtle Pot. These were positive. Good
|
|
flow of water during the test.

|
$bMethod $b
|
|
The method $bwas $b basically that outlined in the Yorkshire Subterranean Journal
|
|
No. 2 pp46-49. Cotton wool was placed in small plastic bags which had had
|
|
holes punched in them with a normal handpunch. These were tied on to diver's
|
|
"Snoopy Loops" (loops of inner tube with a loop of diving line attached) and
|
|
the Snoopy Loops wrapped around a convenient boulder. Where possible the
|
|
bags were covered with other boulders. These detectors proved extremely
|
|
robust, the only ones that were lost weren't placed by me and I suspect that
|
|
they were incorrectly placed. If the site was poorly supplied with boulders
|
|
(such as Meregill Skit) the bags were attached to a diver's lead weight; this
|
|
seemed to work equally well.
|
|
Originally stockings were used in preference to plastic bags. This was
|
|
stopped though when a control detector left in a bowl of water for a week
|
|
developed a thin fluorescent film on it. This despite that fact that the
|
|
stocking showed no obvious signs of fluorescence when tested under UV light
|
|
prior to the construction of the detector. A similar wad of cotton wool in
|
|
a plastic bag showed no fluorescence. All the tests outlined in this article
|
|
were done with plastic bags.
|
|
To try to minimise the possibility of contamination the detectors were
|
|
inspected under a UV lamp prior to placing and, wherever possible, the dye
|
|
and the detectors were handled by two different people. Two detectors
|
|
were placed at each location. When one of these was removed for testing
|
|
it was replaced by another detector. On the tests that were positive this was
|
|
a useful check on whether all the dye had flowed through or whether the
|
|
site was still contaminated.
|
|
Generally positive results were unmistakable with large fluorescent blotches
|
|
round the holes in the bags. The dye did not penetrate very far into the
|
|
cotton wool so there is a danger of the flourescence being hidden by dirt
|
|
if the detector was left in too long. Few detectors were left in for more
|
|
than a month for this reason. The only poor result was from the one at
|
|
Roaring Hole where Leucepher powder was used. A solution seems to be the best
|
|
way of introducing the dye. The dye used for the rest of the tests was
|
|
Photine CS dissolved in Diethyl Glycol Monoethanolamine and water E=90.

A possible dig was identified in the higher regions of the Metallurgy
|
|
Annexe Massif. The geology was mostly silicaceous but there is a definite
|
|
banding of limestone visible on exposures. The dig was opened when a poised
|
|
jammed cast-iron "boulder" was freed. This revealed a window onto a
|
|
large pitch, this was measured as 50ft.
|
|
The pitch, an unbroken hang against the wall, was descended the next day.
|
|
The bottom was choked and all possible extensions closed in
|
|
after a few feet. The system is dry and filled with a loose black dust. There
|
|
is a possible boltable extension to an upper entrance, this could be one of the
|
|
many chimney-like structures visible on the plateau. If this were pushed a
|
|
total vertical range of 25m (80ft) would be achieved.
|
|
The explorers do not think this is part of the sub-magog system and it
|
|
does not bring any nearer the second entrance to Royston cave.

|
|
In 1980, when CUCC started to explore the new route in Stellerweghohle,
|
|
surveying was, for the first time, considered a priority. So it was that
|
|
a party of two surveyed from the Big Pitch to the head of the Big Rift
|
|
using the CUCC Suuntos. The same surveyor returned a few days later with a
|
|
different companion, to survey out from the Big Pitch to the entrance, this
|
|
time with the EXCS Suuntos.
|
|
Back in the camp, calculators were punched, coordinates scribbled, and the
|
|
survey hastily drawn up. The surveyors looked at each other in some
|
|
confusion. The cave seemed to be floating, airborne, across the valley and over
|
|
a cliff. Unable to recall that it had been in daylight with a sense
|
|
of exposure, they came to the conclusion that it was plotted in the wrong place.
|
|
The surveyors retired to the Bar Fischer to consider the dilemma. All
|
|
problems dissolved in a haze of Reininghaus beer fumes as the truth dawned.
|
|
One R.J. Shackleton, who had been is possession of the EXCS compass for
|
|
some time, was in the habit of storing it in the top of his fridge. This has
|
|
resulted in a slight magnetic adjustment, so the survey was now plotted not
|
|
to grid- or true-north, but to fridge-north! What was needed was a little
|
|
calibration, so, armed with a map, both compasses, and several more bottles of
|
|
ale, the party set out to take bearing on local landmarks.
|
|
An hour or so later, it was decreed that the compass was 134$+o $l in error and the
|
|
survey redrawn accordingly. Since it was now inside the hill, all seemed to be
|
|
well. The compass quietly vanished from sight and all accompanying evidence
|
|
was destroyed.
|
|
1981 saw a connection between Stellerweg- and Schnellzughohlen, but serious
|
|
surveying was carefully avoided. 1982 saw CUCC at the bottom of the system,
|
|
and a lot of surveying was undertaken to avoid ever going there again, but
|
|
Stellerweg was not rigged and hence the biggest closed loop kept its secret.
|
|
1983, and our heroes connect the new entrance, 142 (ne$o'e 132), into the system.
|
|
Now comes the critical mistake. Wide-eyed, innocent and pleased with the glory
|
|
brought by pretty surveys, CUCC connect everything together with a half-mile
|
|
closed loop through 142.
|
|
Back in England the greedy computer devours all the numbers and prints out the
|
|
misclosure, about two inches vertically - pretty good that eh? But what's
|
|
this? Just over a Quarter of a Mile out horizontally?!?!?!?
|
|
Detective work soon revealed that a slight rotation would make Stellerweg
|
|
fit very nicely. In fact, the figure turned out to be 46$+o$l. But 46+134 = 180.
|
|
And 180$+o $l is a much more probable figure for a compass error than 134$+o$l. Also,
|
|
when the compass was traced, a sober experimenter found it had precisely the
|
|
error expected. Thus, the survey as published should rotate the section from
|
|
the entrance to the Big Pitch by 46$+o $l clockwise. The streamway from the Big
|
|
Pitch to the Big Rift needs translating appropriately, and the conveniently
|
|
unsurveyed Big Rift is a lot shorter than shown. None of the remainder of the
|
|
system was surveyed with the duff compass, but a big section of the
|
|
Sonnenstrahlhohle survey is also wrong, but that didn't have a north arrow
|
|
anyway (guess why!).
|
|
It is expected that the survey will be redrawn correctly when enough
|
|
additional passage has been found to justify the work involved.

Since the journal is so late this year, here's a brief report on CUCC's
|
|
latest activities.
|
|
Steinschlagschacht bottomed at about 240m, with the rift suddenly becoming
|
|
to narrow to follow. Due to lack of enthusiasm it was not surveyed below
|
|
last year's limit. Wolfehohle also stopped, at a sump, just after 400m, but
|
|
was surveyed. The Wolf, it seems, is actually a Bear of some description.
|
|
We now anticipate a period of mindless recrimination while the
|
|
name is haggled over.
|
|
The attempt to connect into the Stellerweghohle system from above (entrances
|
|
143 and 144) yielded an audible connection, in one direction at least, but is
|
|
too long to be hammered open.
|
|
Some prospecting was done on the plateau, heading towards the Ht. Schwarzmoos
|
|
Kgl., which is getting a depressingly long way from the Car Park. Maybe future
|
|
expeditions will have to camp on the plateau.
|
|
Apart from that, it rained rather a lot. The beer tent was decorated with
|
|
sweetcorn by the simple expedient of heating a can until it exploded. Some
|
|
boy scouts subsequently asked us not to let off fireworks in the middle of
|
|
the night. The landlady at the Staudnwirt also indicated that Meatloaf et. al.
|
|
at full blast tended to drown out the musak in the bar. Still, it was
|
|
discovered that it is possible to have a drunken bop for 4 people
|
|
in the back of a small Land Rover while doing 50 mph. along the road to
|
|
Grindlesee at 3 in the morning.
