<h2>Cave Descriptions of 162 and 163</h2></center>
|
|
|
|
<p align=right>Wookey
|
|
|
|
<p>These are two caves discovered in '88 by Adam which were surveyed (and
|
|
surveyed to) this year by Wookey and Dave F. Both caves are along the side of
|
|
the Hinter Schwarzmoos Kögel, about halfway between 161 and
|
|
Eishöhle. Following the French traverse route along the shelf marked
|
|
with orange spray paint from 161c will take you just below both of the
|
|
entrances.
|
|
|
|
<h3><a id="id162">162</a></h3>
|
|
|
|
<p>162 is about 200m closer to 161 than 163, and is about 250m from vd1. To
|
|
get to it from there, head down the gully directly below vd1 (bearing about
|
|
100°)for about 130m, then turn right, angle right and traverse below the
|
|
bunde field on the right along the most obvious shelf (you should find the
|
|
French path here) for another 130m or so). The cave entrance is a 1.5m by 2m
|
|
hole in the wall to the right of the traverse shelf with a very cold draught
|
|
coming out of it. It is one shelf above the French path, and if you are at
|
|
the wrong level you will miss it.
|
|
|
|
<p>This cave is the larger of the two (33m deep, 159m surveyed length) and
|
|
takes a good couple of hours to explore thoroughly. Through the entrance is a
|
|
large chamber with a 4m by 8m crater in it. A 3m climb down to the bottom
|
|
gives access to a 3m climb back up to the right, leading into the cave and a
|
|
crawl at the lowest point of the boulders leading into a choked bit of cave
|
|
with small solutional stuff in the roof. It is also possible to traverse
|
|
around the left edge of the crater to reach a triangular crawl which goes for
|
|
about 10m before it gets too tight.
|
|
|
|
<p>The entire floor of this cave consists of small rocks and boulders. There
|
|
is no solid rock anywhere horizontal, except halfway down the pitch.
|
|
|
|
<p>After climbing out of the hole there is another 5m deep choked hole
|
|
beyond. Traverses round to both the left and the right are possible, although
|
|
a little care is required due to the low roof and loose floor.
|
|
|
|
<p>To the right, rubble coming out of the bottom of a choked shaft almost
|
|
blocks the passage but a crawl through to the left remains, with a strong
|
|
wind blasting through the confined space. Beyond this constriction the
|
|
draught is lost. The roof remains low on the other side, although it is
|
|
possible to stand up off to the left where there is a 4m climb up to what
|
|
looks like a way on but is actually blind. Moving around the boulder pile to
|
|
the right leads to a big passage. There are a few large boulders 10m to the
|
|
right with a 4m climb down between them leading to a tight choked rift. This
|
|
was also dug into from the top passage by the extremely zealous original
|
|
explorers! There is an alcove in front and a rubble slope up to the right.
|
|
Round the corner to the right is another shaft-bottom rubble pile and a hole
|
|
disappearing into the roof. At the top of the slope to the left is a 4m climb
|
|
up through and around big wedged boulders to reach an impressive chamber 7m
|
|
by 9m and 12m high. There is a possible climb up into an aven in the corner
|
|
which probably doesn't go and has a couple of moves at the top which need
|
|
protecting.
|
|
|
|
<p>Back at the fork near the entrance, turning left and thrutching over a
|
|
couple of rocks (another windy spot) leads to the head of a 17m pitch broken
|
|
by a ledge 8m down. There is a bolt for a ladder hang on this ledge. Going
|
|
off to the left allows a safe traverse past the pitch continuation to the
|
|
bottom of a 6m high rift with some ice in it, slowly narrowing as it goes up.
|
|
|
|
<p>At the foot of the pitch is what looks like an ancient phreatic remnant.
|
|
It is about 40m long and 6m wide, and mostly full of rocks. To the left it is
|
|
blocked at the end by the rubble coming out of the bottom of a big shaft. It
|
|
is possible to work round the foot of this for about 3m to the left and 10m
|
|
to the right.
|
|
|
|
<p>Going the other way down the passage reveals a large snow column by the
|
|
left hand wall. It is possible to climb up between the column and its
|
|
containing shaft, presumably all the way to the surface, but no-one has
|
|
managed it yet. Beyond this column the roof gets lower, apart from a couple
|
|
of solutional avens and eventually a small shaft-bottom rock pile and a
|
|
couple of small inlet tubes mark the end of the cave.

<h3><a id="id163">163</a></h3>
|
|
|
|
<p>This is a fairly small cave remnant (17m deep, 58m surveyed length), but
|
|
it does have a draught at the end suggesting more passage beyond.
|
|
|
|
<p>163 is in the right hand side of a 15m diameter couloir which also has a
|
|
couple of other tubes going off it. The entrance is low and wide (3.5m)and
|
|
descends down a rocky slope for 20m to some impressive ice stals. There is a
|
|
small tube in the roof on the right through which daylight can be seen. The
|
|
cave extends another 10m past the ice stals in fossil passage until it
|
|
chokes. A 3m climb up on the left allows access to a tiny rift which can be
|
|
climbed down for a few uninspiring metres.
|
|
|
|
<p>5m back from the ice stals, towards the entrance, there is a stoop under a
|
|
massive boulder forming the left wall. Here is a 3m climb down into the
|
|
second part of the cave. Downslope from here is a chamber with a small frozen
|
|
stream running through it and a choked alcove containing another ice stal
|
|
beyond the stream. The chamber through which the stream 'flows' appears to
|
|
have been formed by the entire roof falling about 1.5 metres in one piece and
|
|
it is possible to climb underneath this huge rock near the way in. Over on
|
|
the right is a climb through an eyehole to a 3m climb down into a stream
|
|
rift. This has a howling draught coming out of it but it is too small to get
|
|
down - although the heavy application of a hammer might do the trick.
