<b>Location:</b> 204b entrance E 36673 N (52)83716
|

<p>The cave is situated on the west side of the col between the

|
|
|
|
<p><b>Access route:</b>The 1999 route from Top Camp
|
|
(probably near optimal) is a cairned path via
|
|
<span lang="de">Wolfhöhle</span>
|
|
(<a href="../plateau/145.htm">1623/145</a>) and Laser Point 5, then up to the
|
|
top of the bare patch of white limestone visible from Top Camp, passing
|
|
<a href="195.htm">195</a> and <a href="196.htm">196.</a> Laser 0/5 can also
|
|
be approached via <a href="../plateau/107.htm">107</a>, a slightly lower
|
|
route; or the white patch of limestone can be reached by a more central route
|
|
across the plateau. In all these cases there is scope for endless variation,
|
|
and an approach which keeps the large bare patch in view is recommended.
|
|
Alternatively, the cave may be approached from the summit of HSK - probably
|
|
the optimal route if you are coming from any of the
|
|
<a href="161/top.htm">161</a> entrances.

|
|
|
<p><b>Description:</b>204a entrance is directly opposite a 10m x 3m stone
|
|
bridge from which it derives its name. The entrance itself is
|
|
approximately 8m high and 5m wide, and leads down a boulder slope and
|
|
round a right hand bend to the top of the first pitch. 204b entrance is
|
|
15m away to the west, and this is the entrance which is rigged. A 3m
|
|
climb down (handline useful) leads into the entrance gully and a ledge at
|
|
the head of the first pitch, <b>Trick or Treat</b>, opposite 204a
|
|
entrance. This loose, sloping pitch of 20m is rigged from a Y-hang on the
|
|
right hand wall, with a rebelay and deviation. The pitch is tedious to
|
|
prussik on return and is best climbed. The landing is by a large snow
|
|
plug with (in 1999) an ice corridor round the edge leading to the top of
|
|
a boulder slope. A rift passage on the right becomes too tight.
|
|
|
|
<p><a name="jim">Descending</a> the boulder slope (care required to
|
|
avoid kicking rocks off) leads to the head of the second pitch, <b>Jim'll
|
|
Fix It</b> (18m). An unexplored passage is visible from the pitch
|
|
head, which could be accessed by a bolt traverse round the right hand
|
|
side of the pitch head [<a href="204/qm.htm#C1999-204-01" name="qC1999-204-01">C1999-204-01 C</a>]. The pitch is rigged from a bolt in
|
|
the left hand wall with a deviation from a spit immediately after the
|
|
pitch head bolt. This protects a marginal rub point and also avoids a jet
|
|
of water which spurts from a crack in the wall after heavy rain. The
|
|
landing is by a large pointed snowplug. Landing on top of the snow plug
|
|
and climbing up 2m to the right (when facing the wall on which the
|
|
pitch is rigged) leads to an undescended pitch/climb [<a href="204/qm.htm#C1999-204-02" name="qC1999-204-02">C1999-204-02 B</a>]
|
|
which lies above the northern end of
|
|
<a href="#wolp">Wolpertinger Way</a>. In 1999 there was sufficient
|
|
gap between snow and wall to complete the descent and emerge in a sloping
|
|
phreatic passage. There are two ways on: Right leads uphill as
|
|
stooping/crawling height passage for 30m to emerge at the top of
|
|
<a href="#umshit">Umshitshimbo</a>. Left leads downhill into
|
|
<a href="#nearend">The Near End</a> and is the main way on. There is a
|
|
further unexplored passage in the wall above the gap between the snow plug
|
|
and the rock [<a href="204/qm.htm#C1999-204-03" name="qC1999-204-03">C1999-204-03 C</a>].
|
|
|
|
<h3><a name="nearend">The Near End</a></h3>
|
|
|
|
<p><b>The Near End</b> is a collective name for
|
|
a complex network of high level phreatic passages which slope
|
|
approximately 20° following the dip of the beds. Heading
|
|
downhill from the base of <b>Jim'll Fix It</b> in a stooping
|
|
height passage leads round a double bend to a 2m climb down to a
|
|
junction. Right leads to more <a href="#nearside">side
|
|
passages</a> whilst the main route is straight ahead to a
|
|
crossroads. Right leads into the same <a href="#nearside">side
|
|
passages</a> as the previous right turn. Left is <b>Needle Crawl</b>
|
|
past an unexplored passage on the left [<a href="204/qm.htm#C1999-204-04" name="qC1999-204-04">C1999-204-04 C</a>] and
|
|
a crawl on the right (feels like straight ahead) which becomes too small after ~8m.
|
|
Straight ahead (feels like a left) leads to the head of a fine 4m diameter circular shaft, <b>Thread
|
|
Pitch</b>. This pitch of 17m leads into <a href="#wolp">Wolpertinger Way</a>,
|
|
and is likely to be the main route from 2000. A continuation of the crawl is
|
|
visible at the opposite side of the pitch head [<a href="204/qm.htm#C1999-204-06" name="qC1999-204-06">C1999-204-06 C</a>].
|
|
|
|
<p>From the crossroads, the main route in 1999 was straight ahead, downhill
|
|
in mostly stooping height passage with a short section of sandy crawling.
|
|
After 15m is a short climb down to the top of a 4m deep pit with a too-tight
|
|
passage at the bottom, with the phreatic passage continuing to the right.
|
|
After a further 10m the passage is intersected by a large rift with a big
|
|
rock partially blocking the passage. Climbing up to the right leads back into
|
|
a tall rift in the <a href="#nearside">side passages</a>. A climb up to the
|
|
left leads to a passage containing attractive white mud which was not
|
|
entered, however a visual connection to the <a href="#pendulum">Pendulum
|
|
Pitch</a> was established.
|
|
|
|
<p>Straight ahead leads to a further junction after 15m. Left opens out to
|
|
the head of <a href="#pendulum">Pendulum Pitch</a>, the main route to the
|
|
bottom of <a href="#wolp">Wolpertinger Way</a> used in 1999. Right leads to a
|
|
narrow stooping height passage which continues for 25m with several clear
|
|
pools in the floor to a widening where most routes ahead and to the left are
|
|
choked with boulders. To the right, a body sized tube leads upwards for ~15m
|
|
before opening out into a low chamber on the left. The continuation of
|
|
the crawl is immediately opposite the entry point [<a
|
|
href="204/qm.htm#C1999-204-05" name="qC1999-204-05">C1999-204-05 B</a>]
|
|
and there is a climb down into a rift on the far side of the chamber to
|
|
the left [<a href="204/qm.htm#C1999-204-07"
|
|
name="qC1999-204-07">C1999-204-07 B</a>]. The chamber doubles back on
|
|
itself to the left and encounters an area of breakdown which was not
|
|
fully investigated, but is presumed to be the opposite side of the
|
|
boulder choke.
|
|
|
|
<h3><a name="nearside">The Near End: Side Passages</a></h3>
|
|
|
|
<p>The first two right turns encountered when heading downhill
|
|
from the foot of <a href="#jim">Jim'll Fix It</a> unite in a walking
|
|
sized passage. After 10m the bottom of <a href="#umshit">Umshitshimbo</a>
|
|
is passed on the right, whilst straight ahead leads to a junction
|
|
with a large keyhole passage. Left leads after 15m to a climb up
|
|
behind a precariously placed boulder, to an immediate climb down
|
|
of 4m which emerges in the 1999 main route through the near end
|
|
before <a href="#pendulum">Pendulum Pitch</a>. Right leads
|
|
immediately to an undescended pitch [<a href="204/qm.htm#C1999-204-08" name="qC1999-204-08">C1999-204-08 B</a>]. A difficult and
|
|
exposed traverse round the left hand wall leads to a further 30m
|
|
of passage with a steadily lowering roof culminating in a boulder
|
|
choke.

<h3><a name="umshit">The Near End: Umshitshimbo and Updip
|
|
Passages</a></h3>
|
|
|
|
<p><b>Umshitshimbo</b> is a fine phreatic ramp, 2m wide and about 4m
|
|
high, which heads uphill in a straight line for 40m. At the top a
|
|
passage doubling back on the right leads back to the base of
|
|
<a href="#jim">Jim'll Fix It</a> and there is a climb up into a rift passage
|
|
heading south over the top of Umshitshimbo which becomes too narrow. Large
|
|
passage continues uphill past a 2m deep blind pit on the right to a junction.
|
|
|
|
<p>Left leads uphill past a choked inlet on the left to a steep
|
|
uphill section with a crawl on the right, which leads shortly to
|
|
a 2m climb down and immediate choke. At the top of the steep
|
|
section the passage to the right immediately chokes, whilst left
|
|
is <b>Dolly Parton climb</b>, a 2m climb up with huge jugs, to a further
|
|
15m of upward trending phreatic passage, terminating in a boulder choke
|
|
with a slight draught (air coming into the cave.) There are two small
|
|
steep phreatic ramps on the left hand side of this passage, both very
|
|
small and both choked.
|
|
|
|
<p>Straight ahead at the junction leads through a short section
|
|
of rift to an enlargement with an alcove on the right and a
|
|
keyhole passage ahead. The rift section at the bottom quickly
|
|
becomes choked, with a slight draught coming in. A 3m climb gains
|
|
access to the phreatic section which goes over the top of the choke, and
|
|
about after a further 3m reaches a large boulder, which almost blocks the
|
|
passage with a strong breeze blowing through the gap (into the cave.)
|
|
Squeezing through yields a steeply ascending rocky crawl which chokes
|
|
after about 5m.

<h3><a name="wolp">Wolpertinger Way</a></h3>
|
|
|
|
<p><b>Thread pitch</b> from <a href="#nearend">The Near End</a>
|
|
lands at the top of a large 6-8m diameter phreatic passage,
|
|
<b>Wolpertinger Way</b>, which heads downhill past some ice formations on
|
|
the left hand side, for 35m to a junction. Straight ahead is a steep
|
|
gully leading to a 6.5m diameter circular shaft with aven above -
|
|
<b>You're So Veined</b>. There is a traverse round the right hand side of
|
|
the gully on an increasingly narrow ledge.
|
|
|
|
<p><b>You're so Veined</b> is rigged at its southern end, and this is
|
|
reached via a sandy crawl off to the right from the top of the steep gully,
|
|
which passes over a hole in the floor through dangerous boulders
|
|
[<a href="204/qm.htm#C1999-204-09" name="qC1999-204-09">C1999-204-09 C</a>] to reach a junction. Right is an unexplored passage
|
|
[<a href="204/qm.htm#C1999-204-10" name="qC1999-204-10">C1999-204-10 C</a>], straight ahead leads into <a href="#110aday">110 A Day</a>,
|
|
whilst left is the main route.
|
|
|
|
<p>More sandy crawling leads to a crossroads, where left leads to
|
|
the ledge overlooking the pitch, and right is a short crawl leading
|
|
to the main passage part of the way down <a href="#pendulum">Pendulum
|
|
Pitch</a>, the easiest route to the <a href="#elephant">White
|
|
Elephant Series</a>. Straight ahead leads to a further junction.
|
|
Right is a short passage to a traverse round a blind pit, an
|
|
alternative route to <a href="#pendulum">Pendulum Pitch</a>. Left
|
|
is the head of <b>You're So Veined</b>, the start of the
|
|
<a href="#ariston">Ariston Series</a>. </p>
|
|
|
|
<h3><a name="110aday">110 A Day</a></h3>
|
|
|
|
<p><b>110 A Day</b> is a long, dusty passage which varies between stooping
|
|
and crawling for 110m. Immediately after the start is a sharp right hand bend
|
|
with an unexplored crawl straight ahead [<a href="204/qm.htm#C1999-204-11" name="qC1999-204-11">C1999-204-11 C</a>]. About halfway along
|
|
is a crossroads, where low passages lead off to left and right
|
|
[<a href="204/qm.htm#C1999-204-12" name="qC1999-204-12">C1999-204-12 C</a> and <a href="204/qm.htm#C1999-204-13" name="qC1999-204-13">C1999-204-13 C</a>]. At the terminus reached in 1999, the
|
|
passage splits into two. Each branch immediately becomes tight, but could be
|
|
pushed further with a little determination and effort [<a href="204/qm.htm#C1999-204-14" name="qC1999-204-14">C1999-204-14 C</a> and
|
|
<a href="204/qm.htm#C1999-204-15" name="qC1999-204-15">C1999-204-15 C</a>]. In the left hand branch, just before the passage becomes
|
|
tighter, is an undescended pitch [<a href="204/qm.htm#C1999-204-16" name="qC1999-204-16">C1999-204-16 A</a>] of perhaps 20m.
|
|
|
|
<h3><a name="pendulum">Pendulum Pitch Route</a></h3>
|
|
|
|
<p><b>Pendulum Pitch</b> is in a large rift. The first section is a
|
|
loose boulder slope (care required) to a rebelay, then a descent
|
|
of 23m via a deviation off the far wall below a large wedged
|
|
boulder. There may be a passage on the far side of the rift accessible
|
|
with difficulty from this boulder [<a href="204/qm.htm#C1999-204-17" name="qC1999-204-17">C1999-204-17 C</a>]. From the base of the
|
|
pitch, two rift passages lead off which very quickly become too tight.
|
|
|
|
<p>The main route on is reached by swinging off after 16m into a
|
|
6m wide passage. Two passages in the left hand wall are quickly
|
|
encountered. The first quickly becomes too tight, the second is a
|
|
short crawl leading into the network of sandy crawls at the bottom of
|
|
<a href="#wolp">Wolpertinger Way</a>, and is the best route from here to the
|
|
<a href="#ariston">Ariston Series</a>. Continuing down the main passage,
|
|
passing either side of a huge boulder, reaches a blind pit in the floor, with
|
|
two ways on.
|
|
|
|
<p>A loose and slightly precarious traverse round the blind pit
|
|
leads to a short passage on the left, emerging at the head of <b>You're
|
|
So Veined</b> at the start of the <a href="#ariston">Ariston Series</a>. A
|
|
rift visible at the opposite side of the pit has an audible connection to
|
|
<b>You're so Veined</b>.
|
|
|
|
<p>To the right at the blind pit is a draughting phreatic tube which heads
|
|
downhill at a comfortable walking size past a tight passage on the left
|
|
[<a href="204/qm.htm#C1999-204-18" name="qC1999-204-18">C1999-204-18 C</a>]. After 20m, a 3m climb up into a roof tube on the right hand
|
|
side is the way into the <a href="#elephant">White Elephant Series</a>.
|
|
The phreatic passage continues for a further 15m past a too tight inlet on
|
|
the right and a traverse over a blind pit to a 3m deep hole in the floor,
|
|
which is blind. Traversing over the hole and up a loose climb with a too
|
|
tight rift in the right hand wall leads into an uphill passage, which is
|
|
choked with mud after 5m. A sandy crawl on the right just before the
|
|
choke leads via a left hand bend with a too tight rift on the right
|
|
(probably connecting to that at the loose climb) ending at a 2m climb
|
|
down. There is a possible way on at the bottom of this, but it is very
|
|
small and tall people at least would have to enter feet first
|
|
[<a href="204/qm.htm#C1999-204-19" name="qC1999-204-19">C1999-204-19 C</a>]. There is a noticeable draught here blowing downhill (into
|
|
the cave).

<h3><a name="ariston">Ariston Series</a></h3>
|
|
|
|
<p>The Ariston Series is the route to the current deepest point in the
|
|
cave. The pitch series begins with a short pitch of 5m rigged from a large
|
|
thread in the roof a few metres back, with a single spit for the
|
|
vertical part, which is almost a scramble. This lands on a large
|
|
ledge formed of boulders wedged across a narrow point; there are
|
|
two choices of descent here, one to the north, <b>You're So
|
|
Veined</b> (15m), which was used in 1999, and an as yet
|
|
undescended pitch to the south, which will land further down the
|
|
Ariston Series, which should probably be used in 2000. One
|
|
rebelay provides a good hang against the wall of You're so Veined
|
|
to reach the foot of the pitch, which is in a spacious shaft,
|
|
with an impressive aven above. From here, there are two ways on:
|
|
to the left, facing away from the pitch just descended, is a
|
|
gully, which in 1999 contained a thick layer of ice. Carefully
|
|
traversing this rather slippery section leads to the head of a
|
|
small pitch of 6m, which was rigged with a Y-hang. From here a walking
|
|
size phreatic passage leads off, carrying a substantial breeze.
|
|
The passage initially descends, but then develops a narrow floor
|
|
trench; as the trench deepens, the phreatic part of the passage
|
|
rises, and then ends abruptly where the floor trench turns right
|
|
and leads off as a too-tight rift while ahead the phreas pinches
|
|
out.
|
|
|
|
<p>Back at the foot of <b>You're So Veined</b>, a way on to the right
|
|
leads into a small, very crumbly chamber, from which a short section of
|
|
awkward rift leads to a fine crow's nest in the wall of a large rift. A
|
|
very short pitch (5m) lands on a large ledge, from which a roped traverse
|
|
along the left-hand wall gains the head of the next pitch of 12m, which
|
|
avoids a large ledge which would have been in the way but for the
|
|
traverse. This pitch currently requires a rope protector just below the
|
|
Y-hang at the top. The landing is on another large ledge, where a pool can
|
|
be used to refill water containers. It is thought that the alternative
|
|
pitch to You're so Veined will land here, if rigged.
|
|
|
|
<p>The next pitch of 14m consists of a backup bolt followed by a Y-hang,
|
|
which utilises one very cratered spit, which can only be used with a
|
|
bollard type hanger. This pitch requires a deviation from the opposite
|
|
wall or a rebelay to be installed as there is currently a rub point just
|
|
below the Y-hang. The ledge that this pitch lands on consists of boulders
|
|
wedged across the shaft, although it seems sound. A backup bolt protects
|
|
the approach to the Y-hang at the head of the next pitch (35m).
|
|
Unfortunately, it seems to be impossible to get a clean hang from here,
|
|
and a rub-point 3m down will require the installation of a rebelay or
|
|
deviation in future. Immediately after this point, the walls of the shaft
|
|
bell out, and the rope hangs in stimulating isolation. About 5m from the
|
|
floor a ledge is passed, which could be gained by a swing across, where
|
|
there may possibly be a passage leading off [<a href="204/qm.htm#C1999-204-20" name="qC1999-204-20">C1999-204-20 B</a>].
|
|
|
|
<p>At the foot of the pitch, the way on is a very chossy, sloping descent
|
|
which will require either re-rigging or bypassing (which may be possible
|
|
by a climb up and over) in future. This leads to a further short pitch
|
|
(10m), which lands in an aven chamber of ample proportions. From here is
|
|
another short, undescended pitch [<a href="204/qm.htm#C1999-204-21" name="qC1999-204-21">C1999-204-21 A</a>], a crawl leading off from
|
|
the foot of the pitch just descended, and a descending rubble slope. The
|
|
rubble slope curves round to the right, passing a tight rift on the left
|
|
[<a href="204/qm.htm#C1999-204-22" name="qC1999-204-22">C1999-204-22 C</a>], to reach the bottom of a short climb up of 3m on the right,
|
|
which is followed by a scramble down on the other side. From here,
|
|
straight ahead is a climb up into the foot of an aven, half-right is a
|
|
short ascending passage leading to a chamber where a traverse around the
|
|
right hand wall leads to a slope down to an undescended pitch
|
|
[<a href="204/qm.htm#C1999-204-23" name="qC1999-204-23">C1999-204-23 A</a>], and full right is a stooping/crawling height phreatic
|
|
passage with a mud floor. This passes on the right the other end of the crawl
|
|
which led off from the foot of the previous pitch.
|
|
|
|
<p>Some 50m of alternate crawling and stooping, including a single point
|
|
where the roof dips and the crawl is flat-out, leads to a small chamber.
|
|
Here there are two holes in the floor. One, which has not been descended,
|
|
is a reasonably large drop (stones bounce off the walls a couple of
|
|
times and then fall free for some 3s)[<a href="204/qm.htm#C1999-204-24" name="qC1999-204-24">C1999-204-24 A</a>]. The other drop is much shorter, and
|
|
is split into two sections by ledges on each wall part way down. The first
|
|
section of 8m reaches these small ledges, where a stream enters from the
|
|
foot of a very large aven. The next section of 11m is wet, and lands on a
|
|
small ledge overlooking a massive shaft. Stones thrown out from here fall
|
|
for 3s. This is believed to be the same pitch as C1999-204-24, which will
|
|
probably prove to provide a drier descent. This ledge is the current limit
|
|
of exploration at -226m.

<h3><a name="elephant">White Elephant Series</a></h3>
|
|
|
|
<p>The White Elephant Series is a series of rift pitches which has not been
|
|
pushed to a definite conclusion, but does not appear especially promising,
|
|
despite carrying a considerable breeze. From the head of the 3m climb up,
|
|
a roof tube leads off. After 8m of crawling, the passage opens out at the
|
|
head of a 2m climb down by a large boulder. A too-tight rift leads off on
|
|
the left, but ahead opens out into a large space, the <b>Millennium
|
|
Dome</b>.
|
|
|
|
<p>A 20m pitch rigged from a bolt on the left hand wall backed up to the
|
|
big boulder, with a rebelay and rope protector after 5m, lands on the
|
|
boulder floor of the Millennium dome, which is an L-shaped chamber at the
|
|
base of a large aven, with each arm of the L being 15m long and 5m wide.
|
|
There do not appear to be any ways through the boulders, but a rift leads
|
|
off at the western end, quickly arriving at the head of a 10m pitch with a
|
|
constricted take off, rigged from boulders. An eyehole part way down this
|
|
pitch appears to lead into a parallel shaft [<a href="204/qm.htm#C1999-204-25" name="qC1999-204-25">C1999-204-25 B</a>]. The pitch lands
|
|
on a rubble floor with a blind pit. Heading south quickly reaches a loose
|
|
pitch head, with a rift passage continuing beyond.
|
|
|
|
<p>The pitch is 28m, rigged from a bolt on the left hand wall and
|
|
deviations from natural threads after 4m and 12m. The second deviation is
|
|
by a small rock bridge, where descending either side appears to go to the
|
|
same place, and an eyehole opposite connects to the continuation of the
|
|
rift at the top of the pitch. The base of the pitch is an oddly shaped
|
|
chamber formed from several rifts (about 7m up the pitch, these rifts
|
|
coalesce to form a single shaft.) North from the base of the rope leads to
|
|
a 3m climb down into an inlet rift coming from the north which ends in a
|
|
blank wall 8m from the base of the rope, but the rift continues too-tight
|
|
heading south beneath the 3m climb. South from the base of the rope is
|
|
another rift heading downhill which rapidly becomes too tight with running
|
|
water clearly audible, but not visible beyond. West from the base of the
|
|
rope leads to junction with a too tight rift continuing to the west, and
|
|
another inlet rift coming from the north which ends in a blank wall after
|
|
5m.
|
|
|
|
<p>Traversing over the top of the pitch (rope required) and a short descent
|
|
leads to a continuation of the rift passage. A hole on the left connects to
|
|
the 28m pitch described earlier. After 5m the rift narrows and a constricted
|
|
pitch head is reached. The descent of 15m is rigged from a large boulder and
|
|
leads immediately to a further drop of 7m rigged from a bolt. This shorter
|
|
drop may be bypassed by an alternative free climb in a narrow slot
|
|
immediately beyond the pitch head. From the base the tall, narrow rift
|
|
continues with two short climbs and a slot in the floor which gradually
|
|
widens to the head of the next pitch after 6m. This is rigged from a Y-hang
|
|
on either side of the rift, but soon opens out to give a fine descent of 15m
|
|
landing in a spacious rift at 182m depth from 204b entrance. A narrow slot in
|
|
the floor develops, which is just large enough to descend, but stones thrown
|
|
down sound dead [<a href="204/qm.htm#C1999-204-26" name="qC1999-204-26">C1999-204-26 B</a>]. It is possible to traverse above the slot
|
|
for a short way before the rift becomes too tight.
|
|
|
|
<p>There is a noticeable breeze at the base of this pitch, as there is
|
|
through much of the series, with air blowing into the cave. From the base
|
|
of the 7m pitch, there is no roof visible. This area has potential, but
|
|
there are no easy leads, and some lunatic bolt traverses may be required
|
|
to try to bypass the tight sections.
