<p><b>Altitude:</b> 1700m, Depth 128m (deepest surveyed point is -118m)
|
|
|
|
|
|
|
|
|
|
<p><b>Location:</b> 400m NNE of The Nipple <span lang=de>(Weißen
|
|
|
|
|
Warze)</span> at the base of a wall to the left after passing a sandy
|
|
|
|
|
depression (walking from the Nipple).
|
|
|
|
|
|
|
|
|
|
<p>A body-width passage formed by a wall on the left and a large detached
|
|
|
|
|
slab on the right descends for about 5m at 45°, with occasional glimpses
|
|
|
|
|
of daylight above. A cross passage is then encountered. To the right is
|
|
|
|
|
blocked after a few metres, but left descends to meet the base of the wall.
|
|
|
|
|
To the right here, a 20-22cm squeeze is passed by lying on one side. After
|
|
|
|
|
2m of further tight progress, the rift opens onto a drop. A steep tube
|
|
|
|
|
descends for about 12m to a small chamber and with care can be descended
|
|
|
|
|
free.
|
|
|
|
|
|
|
|
|
|
<p>From the chamber, the passage curves to the left and opens onto the head
|
|
|
|
|
of a 7m pitch, which drops onto a large ledge. A rebelay just over the lip of
|
|
|
|
|
the ledge at the left hand side gives a further 18m free-hanging pitch to a
|
|
|
|
|
landing on boulders several metres across, which appear to be jammed across
|
|
|
|
|
the shaft.
|
|
|
|
|
|
|
|
|
|
<p>A narrow rift around a corner stops at a drip and a small pool. The way on
|
|
|
|
|
is through a gap to a hole with a jammed block. Climbing down to the block
|
|
|
|
|
leads to the head of an 18m pitch which rapidly opens into a huge split-level
|
|
|
|
|
chamber. The pitch lands on <b>Big Bertha</b>, a boulder some 4m in diameter.
|
|
|
|
|
|
|
|
|
|
<p>To the north, a narrow rift has been followed for about 10m to a tight
|
|
|
|
|
vertical drop of at least 5m down the rift, but this has not been pushed.
|
|
|
|
|
East from Big Bertha leads to a 5m drop to the lower half of the chamber,
|
|
|
|
|
which is floored with loose rock. An archway to the left leads to a 7m pitch
|
|
|
|
|
to a small stream. This disappears down an impassable slot, but is met lower
|
|
|
|
|
in the cave.
|
|
|
|
|
|
|
|
|
|
<p>From the archway, a climb up behind a boulder propped against the side of
|
|
|
|
|
the chamber leads to a col. One side rapidly curves up to the roof. The other
|
|
|
|
|
ascends over very loose boulders for at least 25m (15m vertical) until the
|
|
|
|
|
roof is met. This area has not been exhaustively pushed, but seems unlikely
|
|
|
|
|
to lead anywhere.
|
|
|
|
|
|
|
|
|
|
<p>Descending the other side of the col gives a series of ledges via 5m, 7m
|
|
|
|
|
and 8m pitches, in a canyon some 5m wide and at least 15m high. The stream
|
|
|
|
|
enters at the bottom of the 7m pitch. Below, the rift continues down a
|
|
|
|
|
moderate slope and round a corner, with a final short 4m pitch to a soil and
|
|
|
|
|
rock floored chamber.
|
|
|
|
|
|
|
|
|
|
<p>A strong draught is felt around the edges of the chamber, rising from the
|
|
|
|
|
choked floor. It is possible to descend in loose boulders in a number of
|
|
|
|
|
places but all ways meet the roof and choke - pushing in this area is
|
|
|
|
|
dangerous and unpromising.
|
|
|
|
|
|
|
|
|
|
<p>Near the bottom of the previous pitch, a 5m deep circular pit in the floor
|
|
|
|
|
can be descended. This takes a large drip from the stream above. At the
|
|
|
|
|
bottom, a tight (22-26cm) rift leads on for 3m to a further 3m pitch to a
|
|
|
|
|
small chamber. An impassable passage continues, while a small window gives a
|
|
|
|
|
view of a widening beyond.
