<p><b>Location:</b> On plateau, beyond <a href="198.htm">B11</a> (1623/198).
|
|
This is a snow-choked shaft next to the very large snow-choked shaft, which
|
|
has always been blocked with snow and was therefore not explored or numbered
|
|
for many years, but is now <a href="189.htm">189</a>.

164 entrance (left of centre) seen over 189 entrance.
|
|
|
|
<p>The entrance pitch is 10m, and has a detectable draught - quite strong in
|
|
view of the size of the entrance. There was only the remains of a snow plug
|
|
in 1988, although the plug is almost complete in some years (eg. 1995 - it was gone again in 1996).
|
|
|
|
<p>A small stream enters and lands on boulders at the foot of the pitch in a
|
|
passage leading south along a fault. A climb of 4m over precarious boulders
|
|
reaches a bolt for the second pitch. The quality of rock in this area leaves
|
|
a lot to be desired. The second pitch, 12m and third pitch, 15m are separated
|
|
only by a small ledge. Water sinks in floor of small passage floored with
|
|
what would appear to be the previous season's roof, now decayed into small
|
|
jagged rocks. Continuing passage over boulders rises to 4-5m dropping steeply
|
|
for 30m on the same south-trending fault. The water is rejoined at a
|
|
freehanging 10m pitch from a rock bridge overlooking a sizeable chamber.
|
|
|
|
<p>The stream sinks at the foot of the pitch in the centre of the 15m by 7m
|
|
chamber floor. To the east, a scramble leads up to a shattered cross-rift
|
|
from a large shelf about 15m long and 10m wide, but ends too tight. A similar
|
|
feature to the west up a 4m climb becomes a low bedding with no way on. Due
|
|
south are two passages, the one to the right leading 20m round a couple of
|
|
bends to a sandy choke. The left passage quickly chokes. The draught seems to
|
|
be lost into the continuation of the passage above the final pitch, on the
|
|
far side of the chamber. This would be best reached by a traverse on steep
|
|
loose rock from the 4m climb in the chamber. The pitches take large
|
|
quantities of water very quickly in rain.
