<h3>DREAMTIME</h3>
|
|
|
|
|
|
|
|
<p>Descend the third pitch to the col below the upper rebelays, between the
|
|
|
|
pitches to Death's Door and Alternative Shopper. Cross the col and climb the
|
|
|
|
boulders to the back wall, then traverse left to gain a large passage, the
|
|
|
|
start of Dreamtime. A traverse line should be used as some boulders are
|
|
|
|
loose.
|
|
|
|
|
|
|
|
<p>The passage descends over boulders and a trench in the floor, with a holes
|
|
|
|
on the right leading into a blind rift, Bullshit Alley. The main passage
|
|
|
|
eventually closes off, but a narrow passage to the right descends to Eyehole
|
|
|
|
Pitch. A hole to the left descends a 20m pitch to an excessively tight rift,
|
|
|
|
which would be near impossible to rig without a power drill. Ahead, Eyehole
|
|
|
|
pitch is a 4m drop into a chamber, with a window back to the 20m pitch.
|
|
|
|
Ahead, climb over or through a rock bridge and down an elliptical tube to
|
|
|
|
enter a bedding plane.
|
|
|
|
|
|
|
|
<p>To the left, the bedding plane leads left to a short pitch to the bottom
|
|
|
|
of the 20m pitch, and right to Gnome Passage, a small winding passage which
|
|
|
|
forks just after a stal boss. The right hand fork eventually closes down, the
|
|
|
|
left hand leads to a drafting choke through which black space can be seen.
|
|
|
|
This might be worth further attention.
|
|
|
|
|
|
|
|
<p>Back at the bedding plane, ahead enters a rift via a handline climb.
|
|
|
|
Traverse over a hold in the floor, and continue until the rift drops right
|
|
|
|
into a pit. Climbing the far side of the pit gains a short passage to
|
|
|
|
Dreaming Pitch. The descends to a short horizontal section, and then Hinge
|
|
|
|
Pitch. Hinge Pitch drops about 10m to become tight, but about 5m down, a
|
|
|
|
ledge can be gained on the right. Climb over a notch and down into a larger
|
|
|
|
passage.
|
|
|
|
|
|
|
|
<p>This passage is about 50m long, over a hole which should preferably be
|
|
|
|
provided with a hand line. This hole has not been descended. At the end of
|
|
|
|
the passage, just before Stinky Pool, climb up to the right into a cross
|
|
|
|
passage, leading to the top of Hole in the Roof Pitch. This descends for 30m
|
|
|
|
via a ledge and rebelay to land on boulders. To the left is a blind pit, to
|
|
|
|
the right a climb down and short section of passage to join the Right Hand
|
|
|
|
route, a few metres above Bungalow Pitch.

<h3>RIGHT HAND ROUTE</h3>
|
|
|
|
|
|
|
|
<h4>Boulder Alley</h4>
|
|
|
|
|
|
|
|
<p>A 5m climb up the left wall at the top of Bungalow Pitch leads into a 4m
|
|
|
|
diameter passage which runs for 20m and then looks out over Boulder Alley.
|
|
|
|
There is also a hole on the right overlooking Poxy Pitch. Traversing out from
|
|
|
|
the hole (needs a rope) across some very friable rock leads to the shaft part
|
|
|
|
way down the Alley.
|
|
|
|
|
|
|
|
<h4>Over The Rainbow</h4>
|
|
|
|
|
|
|
|
<p>Just to the right of the OTR bypass at the same level is a small passage.
|
|
|
|
10m along this is a choice of: straight on; a 2m climb down; or a larger
|
|
|
|
passage on the right which doubles back to a 4m pitch into OTR. Straight on
|
|
|
|
leads to a 3m wide, 2m deep hole in the floor. It is possible but difficult
|
|
|
|
to traverse over it and it is easier to go down the climb and along a lower
|
|
|
|
passage which comes out into this hole, and then climb up the far side.
|
|
|
|
Beyond this the passage veers left and then wiggles back into the main RH
|
|
|
|
Route passage via a choice of routes and sandy climbs down.
|
|
|
|
|
|
|
|
<h4>Vestabule</h4>
|
|
|
|
|
|
|
|
<p>In the Chunnel, 10m before the 3m climb down into OTR there is a small
|
|
|
|
mud-floored passage going off in the right hand wall. This can be followed
|
|
|
|
past a junction on the right with a tiny passage leading back into the
|
|
|
|
Chunnel 10m further along, to a 12m pitch into a 3m wide by 20m high rift.
|
|
|
|
This pitch lands on a boulder 6m above the actual floor. Steep climbs can be
|
|
|
|
followed downwards to the lowest point where a further 8m pitch which is just
|
|
|
|
free-climbable gets down to the choked floor.
|
|
|
|
|
|
|
|
<p>Going uphill from the pitch for 30m leads to a 19m pitch which is also
|
|
|
|
choked. There is a small 15m long passage in the left wall and a 6m climb up
|
|
|
|
the right hand wall 10m back from the pitch leads into a passage which
|
|
|
|
quickly comes back into the Chunnel directly above the OTR climb.

<h3>DEHYDRATION</h3>
|
|
|
|
|
|
|
|
<h4>Staircase 36</h4>
|
|
|
|
|
|
|
|
<p>At the end of Yapate Inlet just beyond a roped traverse over a hole is a
|
|
|
|
7m pitch up 'Staircase 36'. The first ascent was achieved by climbing up the
|
|
|
|
less vertical wall 5m to the left (above Gob on You) and then traversing
|
|
|
|
right along a sloping, muddy ledge. As this was non-trivial, the pitch has
|
|
|
|
been left rigged (1990).
|
|
|
|
|
|
|
|
<h4>Chicken Flied Nice</h4>
|
|
|
|
|
|
|
|
<p>At the top of the pitch is a big phreatic passage ('Chicken Flied Nice'),
|
|
|
|
similar to Yapate but with only a shallow floor trench. After a sharp
|
|
|
|
left-right zig-zag a sandy 2m slope up on the left leads to a T-junction with
|
|
|
|
a rift parallel to CFN.
|
|
|
|
|
|
|
|
<p>To the left it is very narrow and after 20m looks out over Gob on You.
|
|
|
|
|
|
|
|
<p>To the right the rift is much bigger (about 4m by 6m). walking over a few
|
|
|
|
boulders brings you to the foot of a 3m pitch up to the rest of the rift and
|
|
|
|
a 3m climb down over blocks into a young, active stream passage. A couple of
|
|
|
|
2 to 3m climbs back up are possible upstream along this before it gets too
|
|
|
|
tight.
|
|
|
|
|
|
|
|
<p>The main rift continues above the pitch for another 25m past a high aven
|
|
|
|
on the left to rejoin CFN at a sandy bank.
|
|
|
|
|
|
|
|
<h4>Burble</h4>
|
|
|
|
|
|
|
|
<p>The CFN phreatic continues up dip past this junction to a 90° right
|
|
|
|
bend. In the outside wall of this corner is a narrow inlet ('Burble') which
|
|
|
|
goes for 20m to a small chamber with a little stream on the right and a 3m
|
|
|
|
climb on the far side. This leads to a dead straight passage which has been
|
|
|
|
crab-walked for about 60m to an undescended pitch and possible traverse.
|
|
|
|
|
|
|
|
<h4>Strange Downfall</h4>
|
|
|
|
|
|
|
|
<p>Back in CFN the passage changes at the 90° corner; the floor trench
|
|
|
|
cuts down and widens to a high stream rift which opens onto a big space,
|
|
|
|
possibly a partially collapsed shaft. A 23m pitch lands on boulders, where
|
|
|
|
climbing down the boulders to the left reaches a small rift which is fairly
|
|
|
|
full of stones at this point. The rift may be followed in either direction.
|
|
|
|
|
|
|
|
<h4>Hyper Gamma Spaces</h4>
|
|
|
|
|
|
|
|
<p>Turning right and traversing over two 3m deep holes leads to a right turn
|
|
|
|
and a 4m climb down to a chockstone plus another 5m climb down to a boulder
|
|
|
|
choke. Descents can be made in various places along this rift for up to about
|
|
|
|
20m, but all routes seem to choke. This area, including the big chamber is
|
|
|
|
'Hyper Gamma Spaces'.
|
|
|
|
|
|
|
|
<h4>Endless</h4>
|
|
|
|
|
|
|
|
<p>Turning left in the rift immediately gives a very loose 3m climb down to a
|
|
|
|
widening of the rift. This is the start of 'Endless', a steeply descending
|
|
|
|
(35° to 40°) 140m long rift, only 5m high at this end but a good 40m
|
|
|
|
high at the other. From here there is a crawl ahead and to the left, and two
|
|
|
|
climbs down to the right.
|
|
|
|
|
|
|
|
<p>The small crawl goes for some 30m before getting too tight.
|
|
|
|
|
|
|
|
<p>The first climb is about 3m to a pitch aligned with the rift.
|
|
|
|
|
|
|
|
<p>The second climb (of 7m) is the way on. Beneath its foot is a further 3m
|
|
|
|
climb down leading to a rift pitch (probably the same as the one reached from
|
|
|
|
the above). These pitches have not been descended.
|
|
|
|
|
|
|
|
<p>Continuing down Endless leads to various amusing climbs and a junction to
|
|
|
|
the left after 60m.
|
|
|
|
|
|
|
|
<p>A stoop leads through to an angled chamber with a roof tube 7m up the
|
|
|
|
right hand wall which winds somewhat before emerging back in Endless some 15m
|
|
|
|
above the floor (not climbable at this point).
|
|
|
|
|
|
|
|
<h4>Hasta La Vesta</h4>
|
|
|
|
|
|
|
|
<p>20m further on is a 2m climb up and a 5m climb down followed by a couple
|
|
|
|
of loose climbs (beware) leading to Hasta La Vesta - a horrible pile of
|
|
|
|
boulders calling itself a pitch head.
|
|
|
|
|
|
|
|
<p>Just before this there is a hard 5m climb down into a sand-filled dead
|
|
|
|
end.
|
|
|
|
|
|
|
|
<p>About 10m down the appalling HLV pitch a pendulum to the right above two
|
|
|
|
big holes can be made (the wall is very loose).
|
|
|
|
|
|
|
|
<p>From here an ascending rift passage can be followed to an unascended (as
|
|
|
|
most of it fell off when it was attempted) climb. This rift may well be the
|
|
|
|
one continuing beyond Fifty Francis's Phreatic Freehang in Flat Battery as
|
|
|
|
voices have been heard in the area.
|
|
|
|
|
|
|
|
<h4>Captive Wedge</h4>
|
|
|
|
|
|
|
|
<p>Of the two holes, only the right hand one has been descended, although
|
|
|
|
they may connect about 30m down. After a rebelay, Captive Wedge opens out and
|
|
|
|
there is a drippy section then another rebelay far out to the left after a
|
|
|
|
big ledge. From the floor a climb up to the left gives access to a passage
|
|
|
|
containing increasingly awkward climbs. An obvious hole leads to a large
|
|
|
|
shaft with a sloping wall. There is a window in the opposite wall. The
|
|
|
|
obvious way on from the bottom of the shaft becomes too tight. There are
|
2004-04-29 16:24:54 +01:00
|
|
|
several mud choked passages radiating from the bottom of the pitch. <hr />
|
2001-08-15 19:29:27 +01:00
|
|
|
|
|
|
|
<h3>FLAT BATTERY</h3>
|
|
|
|
|
|
|
|
<p>This consists of a long series of pitches from ledge to ledge down to a
|
|
|
|
complex phreatic level where the way on is blocked by sand.
|
|
|
|
|
|
|
|
<p>30m back from the end of Yapate Inlet is a sandy slope up to the a
|
|
|
|
straight rift forking off on the right. This apparently ends quickly in a
|
|
|
|
narrowing climb but ducking under the right wall, down a slope and over a
|
|
|
|
boulder which 'obviously' blocks the passage, leads to a small chamber. There
|
|
|
|
is a floor-level dead-end flat out crawl ahead, a steep passage up (the way
|
|
|
|
on) to the left and a tiny roof tube ('Short Circuit') which also connects to
|
|
|
|
the way on but which is impassable.
|
|
|
|
|
|
|
|
<h4>Oldham Pitch</h4>
|
|
|
|
|
|
|
|
<p>The passage comes out at a double pitch head (two holes leading to the
|
|
|
|
same place). Above is more shaft, the top of which can be reached by a climb
|
|
|
|
back in Yapate, and an audible connection to the approach rift.
|
|
|
|
|
|
|
|
<p>Down the 25m Oldham pitch is a stream rift to a 6m pitch. At the foot of
|
|
|
|
this is a hole down and a squeeze along a rift to the right.
|
|
|
|
|
|
|
|
<p>Through the hole is 3m climb down to a damp view along a too tight rift.
|
|
|
|
|
|
|
|
<h4>Triple A</h4>
|
|
|
|
|
|
|
|
<p>The first squeeze is 'AA' ('Double A') and 1m beyond it is another ('AAA'
|
|
|
|
or 'Triple A') which is great fun, especially with tackle, as it is angled
|
|
|
|
down to the head of 'Jackpot', an 8m pitch.
|
|
|
|
|
|
|
|
<h4>Fifty Francis's Phreatic Freehang</h4>
|
|
|
|
|
|
|
|
<p>The rift becomes much bigger beyond Jackpot and across the ledge is a 13m
|
|
|
|
pitch 'NiFe' leading via another ledge to Fifty Francis's Phreatic Freehang,
|
|
|
|
a stunning 40m free pitch. At the foot of this is a 2m climb up to the
|
|
|
|
continuation, which can be seen through a hole ('Maud's Window') in a rock
|
|
|
|
arch ('The Mathematical Bridge') at the foot of a further 3m climb down from
|
|
|
|
where FFPF lands.
|
|
|
|
|
|
|
|
<p>The continuation is yet another pitch of 15m with a space off to the right
|
|
|
|
which connects with Ariadne's aven below. At the bottom of this pitch is a 1m
|
|
|
|
diameter hole onto a final 8m pitch ('FX2') to the phreatic level
|
|
|
|
('Electrolyte Level').
|
|
|
|
|
|
|
|
<h4>Electrolyte Level</h4>
|
|
|
|
|
|
|
|
<p>To the left of FX2 is a pair of high avens ('Ariadne's Aven') with a
|
|
|
|
beautiful pocked and pebbled floor. At the back of the aven there is a 4m
|
|
|
|
climb up to nothing very exciting.
|
|
|
|
|
|
|
|
<p>To the right is a 2m sandy climb to a roped traverse around a 10m long 4m
|
|
|
|
deep hole.
|
|
|
|
|
|
|
|
<p>Near the foot of FX2 the passage cuts down below the sand and rock floor.
|
|
|
|
It is easy to climb down into this but it soon becomes sufficiently tight to
|
|
|
|
require removal of SRT gear. Following this tortuous passage through a small
|
|
|
|
choke leads back out into the main passage at the bottom of the traverse
|
|
|
|
hole.
|
|
|
|
|
|
|
|
<p>In the right hand wall of the hole is a 1.5m by 0.5m passage. This also
|
|
|
|
soon requires gear removal and is both small and has a couple of athletic
|
|
|
|
bits. After about 30m it crosses an even more ridiculous passage which could
|
|
|
|
possibly be followed if this was Mendip. Beyond this there are several
|
|
|
|
zig-zags of slightly uphill flat-out crawling culminating in a nasty duck
|
|
|
|
which can be baled to make it a bit less awful. Beyond this is a fork with a
|
|
|
|
difficult skydive (Quaking-style) 3m climb/pitch to the left into what looks
|
|
|
|
like larger passage. This would require some rigging to re-ascend.
|
|
|
|
|
|
|
|
|
|
|
|
<p>Right at the fork is a steeply ascending (55°) passage through which
|
|
|
|
at least an audible connection back to the main passage probably exists. It
|
|
|
|
was not followed due to lack of time and enthusiasm, but the sound of bolting
|
|
|
|
was heard.
|
|
|
|
|
|
|
|
<p>Beyond the hole the sandy-floored passage continues past a 0.3m diameter
|
|
|
|
hole in the floor. This is a tight 3m pitch down to a sand-choked chamber.
|
|
|
|
|
|
|
|
<p>The passage ends in an amazing 8 inch thick false compacted sand floor and
|
|
|
|
a 5m pitch down to a sand slope. This chokes at the bottom, and the top leads
|
|
|
|
into a large chamber with a cracked mud and sand floor. There is a choked 15m
|
|
|
|
pitch in the floor, a small tube to the right and a 4m pitch up the opposite
|
|
|
|
wall.
|
|
|
|
|
|
|
|
<p>The tube descends for about 10m to a small rift. A climb up for about 5m
|
|
|
|
is possible before it gets too wide and muddy.
|
|
|
|
|
|
|
|
<p>Up the 4m pitch the ascent continues via a short climb and a 3m
|
|
|
|
free-climbable pitch to a boulder-floored chamber. A loose tube leads back
|
|
|
|
down from here to the sandy chamber and there is a 5m pitch down to an
|
|
|
|
impassable rift. Off to the right is a crawl to a T-junction. Left it soon
|
|
|
|
gets too tight. Right leads to a pitch which looks down on the 5m climb up
|
|
|
|
from the small rift mentioned above.

<h3>FLAPJACK II</h3>
|
|
|
|
|
|
|
|
<p>This leads off from -50m down Flapjack at a rather convenient ledge. Back
|
|
|
|
behind the ledge, a narrow rift leads off via two small pitches (7m and 7m)
|
|
|
|
to a small chamber with water entering in one corner. The continuation of the
|
|
|
|
rift ('No, you go first') is more complex with different levels (guide string
|
|
|
|
remains) and an awkward last right hand corner. Rift leads to top of an 8m
|
|
|
|
pitch into a larger chamber.
|
|
|
|
|
|
|
|
<h4>Too Much Too Soon</h4>
|
|
|
|
|
|
|
|
<p>The character of the cave changes as the chamber opens into a 100m pitch,
|
|
|
|
'Too Much Too Soon'. Traverse to right and up to reach a Y-hang (42m
|
|
|
|
free-hang). No other ways continue. The pitch lands on a big ledge at
|
|
|
|
-65/70m, and there is a further ledge 10m down. From here a final rebelay
|
|
|
|
gives a 20/25m hang down last section of 5m phreatic riser to land on
|
|
|
|
squelchy muddy floor, 'Splatdown'. Opposite the landing point is a small tube
|
|
|
|
leading to a 3m climb. A 6m climb follows down to a small chamber from which
|
|
|
|
an impenetrable rift drops 8 to 10m to water.

<p>An impressive pitch series that doesn't seem to go anywhere.
|
|
|
|
|
|
|
|
<p>At the corner before Arrow Chamber there are a couple of fallen blocks and
|
|
|
|
some holes in the floor. The smallest hole, on the outside of the corner was
|
|
|
|
the way chosen although they all seem to go into the same rift. This first
|
|
|
|
pitch is 7m down to the stone-covered Foulness Ledge. From here is the
|
|
|
|
classic 35m Dounreay pitch down to a ledge.
|
|
|
|
|
|
|
|
<p>From here you can continue down a further 5m pitch (Sizewell A) or go
|
|
|
|
through a rift to the left to another 5m rift pitch (Sizewell B). There is a
|
|
|
|
visual connection between the bottom of these two pitches.
|
|
|
|
|
|
|
|
<p>There is a further 3m drop from the bottom of Sizewell A to a floor with a
|
|
|
|
narrow hole in it and a boulder slope up to a window onto a big space,
|
|
|
|
probably the top of Dinorwig, and a very awkward, tight passage just to the
|
|
|
|
left of the window. This looks over a couple of holes in the floor and has
|
|
|
|
not been pushed.
|
|
|
|
|
|
|
|
<p>Through the narrow hole is a 9m pitch to a ledge looking out onto a
|
|
|
|
massive shaft. This is Dinorwig, a 53m pitch with a small rift at the bottom.
|
|
|
|
A 4m pitch under a large boulder leads to a 13m pitch. Halfway down this on
|
|
|
|
the left is a dead end passage. At the bottom are a couple of small ways off,
|
|
|
|
both of which are blocked.
