Journal CU's 1991,92 says VSK 210° but this has to be a typo, maybe 110 ?<br>

|
|
|
|
<p>The main entrance joins with a secondary, slightly smaller entrance in a
|
|
daylit chamber on top of a snow plug. Sky can be seen through a third
|
|
entrance in the ceiling, which is surrounded by undergrowth on the surface.
|
|
A hole down the back edge of the snow plug leads to a slither down a
|
|
partially iced steep (30°) boulder slope, with a low ceiling which soon
|
|
rises. A large boulder several metres across is jammed across the slope at a
|
|
few metres further down, below which the boulder slope continues. An inlet
|
|
to the left just before an ice formation soon becomes too tight. Carrying
|
|
on, the slope soon gives way to a traverse above a vadose canyon, with a
|
|
laddered climb (6m) after about 25m. It is possible to continue along the
|
|
top of the rift all the way to above the top of shell pitch. It is much
|
|
more spacious than below but has a couple of bad steps.
|
|
|
|
<p>From the bottom of the ladder, the passage soon drops down a climb of 2m.
|
|
Then there is a winding, rifty passageway, named "<b>Magic Mushroom
|
|
Passage</b>" due to the peculiar mushroom-like formations on the walls.
|
|
These, together with the white dusty look of the walls in places, give the
|
|
cave its name. After 100m the rift widens, and a traverse develops above a
|
|
narrower rift below. The upper level may be followed to above the first rope
|
|
pitch, but the more usual route is to climb down a rock pile into the lower
|
|
rift (40cm wide), which is known as the <b>Yorkshire Ripper</b>, due to the
|
|
effect of the sharp, narrow rift on oversuits, and the Yorkshire feel of the
|
|
cave at this point. After 15m, relieved at one point by a small alcove with
|
|
an irritating spray of water, the narrow rift widens, after a final
|
|
flourish, to the head of the first rope pitch (6m).

|
|
|
|
<p>Carrying on from the base of the pitch, the tiny rift in the floor
|
|
deepens, and traversing along leads soon to the head of <b>Shell pitch</b>
|
|
(19m). Descending gives a fine view of the chamber, the walls of which
|
|
contain many large bivalve fossils (hence the pitch's name). From this
|
|
chamber, a short traverse leads to a junction. Left is an unclimbable aven,
|
|
whilst to the right is <b>Piezo de Resistance</b>, described below. The main
|
|
route is currently down <b>Q8</b> pitch which is broken by a ledge after
|
|
16m. After a further 9m and a rebelay, a pendulum through a window to one
|
|
side leads on. Descending further, the shaft stops after 19m and a further
|
|
rebelay. There are no passable ways on from the bottom (<b>Strike
|
|
One</b>).
|
|
|
|
<p>After the pendulum, a vast army of rebelays lies in wait (<b>Dot to
|
|
Dot</b>), eventually ending in a larger pitch (25m) the bottom of which,
|
|
again, has no ways on (<b>Strike Two</b>).
|
|
|
|
<p>Yet again, a pendulum (at -14m) yields more cave (<b>Bottom Bypass</b>).
|
|
A dubious 11m hang leads to a ledge. At one end of the ledge, ducking under
|
|
an arch enters a chamber at the bottom of a high shaft (<b>Lady's Loo</b>),
|
|
down which a vast torrent pours in wet weather. A further 9m down from the
|
|
ledge is a floor. Progress can be made along the top of a slimy keyhole
|
|
shaped rift (<b>Tarzan's Folly</b>) which is irritating to pass, especially
|
|
with tackle. After 20m, a false floor appears and a few metres further on is
|
|
<b>The Dark Room</b>, a high chamber with dark, textured walls. A waterfall
|
|
cascades down from unfathomable heights, and pounds onto a ledge to the back
|
|
right of the cavern.
|
|
|
|
<p>Climbing down a slimy slope (which in an ideal world would be lined) the
|
|
way on is along a rift which exits from the rear of the chamber on the left
|
|
side. The rift has a couple of false floors in it. The middle level leads to
|
|
the head of the next pitch: <b>Natural Redundancy</b> (11m) is reached after
|
|
about 10m. The rope is belayed to a large chock stone at head level, then to
|
|
a bolt about two inches from a beautifully rounded thread, hence the name.
|
|
<b>Cyclotron</b> pitch follows immediately, then comes <b>Quark, Strangeness
|
|
and Charm</b>, a rift passage with many possible traverse levels. In places
|
|
there are flowstone bosses, and near the roof, some odd <b>tippex</b> stals
|
|
can be seen. The formations are only notable due to their rarity in the
|
|
caves of this region.

<br>Quark Strangeness & Charm

<img alt=" " src="../../icons/lists/tab64.png">Cloud Chamber</center>
|
|
|
|
<p>At the end of QS&C, the passage sweeps round to the left as the floor
|
|
drops away into <b>Cloud Chamber</b>. The pitch is broken by two rebelays.
|
|
The grade 5 survey stops about 20m back from the pitch head. The details of
|
|
the passage leading to the next pitch are uncertain, although the consensus
|
|
is that it is around 20-30m long, and fairly straight. The lack of
|
|
information led to the name <b>Amnesia Alleyway</b>. The next pitch is
|
|
<b>NDE</b>, an acronym for "Near Death Experience", since a party of cavers
|
|
was flood-pulsed just below this pitch during the initial exploration. This
|
|
incident also named <b>The Delicate Sound of Thunder</b>, another rift
|
|
passage with a traverse along to a pitch (<b>Traditional Style</b> - laddered
|
|
in 1991, marking the end of exploration that year).
|
|
|
|
<p>After the first 5m slope to a rebelay, Traditional Style drops 12m (with
|
|
one deviation) to a wide shelf. At the right hand edge is another 12m pitch.
|
|
This lands in a muddy area which quickly becomes a very muddy steeply
|
|
descending rift. An 8m pitch (2 bolts, Y-hang) a bit of clambering and a 5m
|
|
pitch (one bolt) get you to a washing-up-bowl-sized sump at -292m.
|
|
|
|
<p>5m up on the left hand wall (by the last bit of string) is a muddy crawl.
|
|
This is below the 'tide-mark' of the sump so is somewhat oppressive. It
|
|
leads, after 8m to a high parallel rift. A couple of 2m climbs ahead lead
|
|
back down to another, slightly larger, sump. The rift rises at least 20m,
|
|
apparently without connecting back to the main descent route.
|
|
|
|
<h3>Piezo de Resistance</h3>
|
|
|
|
<p>From the head of "Q8" pitch, an alternative route may be followed along
|
|
a rift on a fault at 20-200°, hading 80° to the west. Taking
|
|
the passage to the right, a traverse develops after 10m. Water sinks into a
|
|
hole in the floor after a further 10m, and beyond this, is a 9m pitch,
|
|
followed after 10m or so by a longer pitch of 16mm.

|
|
|
|
<P>This lands on a ledge with an obvious continuation below, but the
|
|
route, to keep away from potential water, takes a much more interesting
|
|
route. It goes up a 6m pitch to the <b>Crow's Nest</b>, a narrow rock rib
|
|
separating two parts of the shaft. This was originally reached by a bolt
|
|
traverse round the right hand wall. From the Crow's Nest, <b>The
|
|
Chimney</b> drops 30m in typical Puffball triangular pitch (elliptical
|
|
joint-aligned phreas cut down on lower side by vadose action). The rope
|
|
stays resolutely on the upper side with a series of epic hanging
|
|
rebelays.
|
|
|
|
<P>At the bottom a 34m freehang lands in the Darkroom, but the bottom of
|
|
this is in the waterfall (noted in the Darkroom description), so the
|
|
route goes through a window near the top of the hang which gives a nice
|
|
dry 30m hang.
