<h2>How to find it</h2>
|
|
|
|
<p>From the stone bridge, follow the cairns towards 204e entrance. Upon
|
|
reaching the final gully, where the path turns up to the right towards
|
|
that entrance, continue straight across and then work to the right,
|
|
traversing around
|
|
the rear lip of a hole. This leads to the bottom of a loose climb, which
|
|
is ascended to reach another level. A prominent Christmas tree style fir
|
|
marks the point where another climb is made to the next level up. It is
|
|
then necessary to ascend to the next level above this, either by a short
|
|
traverse and then a narrow climb between two blocks, or by heading right
|
|
and then heading back up to the left. Having done this, a short ascent
|
|
on small loose stones brings one to the uppermost level, marked by a
|
|
prominent cairn (visible from the stone bridge).
|
|
</p>
|
|
|
|
<p>Follow the cairns around to the left, descending slightly at first and
|
|
then maintaining the same level, to eventually reach a cairned point
|
|
overlooking a large broken gully running from right to left. Descend
|
|
into the gully (passing the shaft of 2004-18) and cross to the other side
|
|
where an obvious level ascends upwards and to the right. Having reached
|
|
the top, follow the cairns to the right to arrive quickly at an area with
|
|
a hole to each side. The shakehole to the left, containing a cairn some
|
|
two feet high, contains the A entrance; the B entrance is the other hole.
|
|
</p>
|
|
|
|
<h2>Entrance shaft</h2>
|
|
|
|
<p><b>Warning:</b> There are a fair number of loose rocks on the entrance
|
|
pitch, particularly in the top section. Rocks that have been dislodged
|
|
could fall almost all the way down the shaft.
|
|
It is advisable for one person to
|
|
descend at a time and for the others to cower in the places marked below, or
|
|
wait at the very bottom by the ice stals.
|
|
</p>
|
|
|
|
<p>The entrance, of moderate proportions, gives onto a
|
|
steeply-sloping shaft that descends for a total of 70m depth. The
|
|
shaft is imposing, and the view up from mid-descent is impressive.
|
|
A thread in
|
|
the bottom of the shakehole is succeeded by a bolt on the left wall under
|
|
the dripline, enabling a descent for several metres to a small ledge.
|
|
Working around to the right here gains a rebelay, succeeded by another under
|
|
a small nose of rock just where the shaft becomes vertical.
|
|
</p>
|
|
|
|
<p>The landing after the rebelay is on a large ledge, partially occupied by
|
|
a large area of snow. There is a bolt here to anchor the rope, and above
|
|
is visible the shaft of the B entrance.
|
|
Upslope leads to an alcove, where it is possible
|
|
to shelter whilst people are on the upper part of the pitch. The rear of
|
|
this alcove opens onto the top of a pitch that appears to be of quite
|
|
some depth [QM B]. Downslope from the landing a traverse is followed on
|
|
the left wall; a bolt low on the wall just before the end provides the
|
|
belay for a scruffy descent of only two metres to another rebelay on a flat
|
|
wall. From here, the descent continues either on top of or alongside a
|
|
large snow plug to a rebelay on the left wall. After this, one continues
|
|
over a section of loose boulders and then drops in an awkward crack to
|
|
a crows' nest known as the Col, where there is a further rebelay. (The
|
|
rigging just above the Col is sub-optimal, and could do with further
|
|
work.) Care should be taken at the Col not to bang one's head on the
|
|
boulders above, as their undersides look loose. The Col provides a further
|
|
place where shelter can be taken from falling debris.</p>
|
|
|
|
<p>Continuing the descent in the main shaft from the Col gains another
|
|
snow plug and the base of the rift holding the Col. It is possible that
|
|
this rift could lead to further passage [QM B], either accessed from this
|
|
point or by descending the pitch on the other side at the Col.
|
|
Abseiling over the snow plug towards the right wall, a high bolt provides
|
|
the belay for the final section of the pitch. The rope rubs on a boulder
|
|
here and a deviation should be installed. The final section drops
|
|
near-vertical for a short distance and then becomes steeply-sloping
|
|
over snow. Gradually, the snow flattens out (passing a possible way on
|
|
to the side of the snow plug on the left wall [QM C]),
|
|
and the bottom is reached
|
|
at a pool of ice. There is an ice stal on the right and another in an
|
|
alcove to the left. The one in the alcove could be ascended with ice and/or
|
|
climbing equipment to reach a passage [QM C].
|
|
On the existing rigging, reaching this point requires
|
|
approximately 100 metres of rope, a long sling, and nine hangers.</p>
|
|
|
|
<h2>First horizontal level</h2>
|
|
|
|
<p>The main way on from the ice pool is a hole at floor level that leads
|
|
into a chamber. Another small hole to the right gives access to
|
|
<b>Bauernkrapfen Passage</b>, a well-formed crawl debouching into a large rift
|
|
chamber, <b>Three Fried Mice</b>. Following the chamber around to the left
|
|
leads to a choke at the bottom of a slope, although before this it is possible
|
|
to climb up the wall and through a hole under boulders to gain a higher level,
|
|
with a view over the chamber before Bauernkrapfen Passage but no other ways
|
|
on.</p>
|
|
|
|
<p>Following the rift around to the right from the end of
|
|
Bauernkrapfen Passage, passing some faulted phreatic tubes in the left wall,
|
|
leads to an opening in the right wall. This sucks strongly and
|
|
continues as a phreatic passage past a delicate traverse over a hole [QM C]
|
|
to eventually arrive at a further hole in the floor. This will require
|
|
rigging to traverse or descend.</p>
