<p><b>Altitude:</b> 1647m, depth 45m<br>
|

<p><b>Location:</b> E 35479, N (52)83052<br>
|
|
700m north of Schwarzmoossattel.
|
|
|
|
<p><b>Marking:</b>M6 stud with alloy tag "CUCC 1993 01" on flat rock NE of
|
|
shaft. This will be replaced with the correct kataster number in due course.
|
|
|
|
<p><b>Access Route:</b> From
|
|
<a href="164.htm">164</a>, avoid <a href="189.htm">189</a> (easiest 15m to
|
|
its right over a small ridge, but OK immediately on its right edge), then
|
|
go roughly NNW (a few cairns - 1996 vintage orange paint has completely
|
|
faded). This leads up onto the right edge of a ridge (the main part of
|
|
which is deep Lätchen), passing right of the OAV ski marker pole.
|
|
This is an easy walk above a short (climbable) cliff looking down onto <a
|
|
href="../newcaves/cu9803">CUCC 1998-03</a>. When this easy walk is
|
|
interrupted by a step down, head leftish over a series of limestone steps
|
|
to reach a descent into a large broken area (near <a
|
|
href="173.htm">173</a>). Climb steeply left up boulders to a large cairn,
|
|
then along a sloping limestone shelf. Shortly ahead is an abrupt
|
|
headwall, below which is the shaft of <b>Lost Rucksack Cave</b> (given
|
|
temporary number CUCC 1993 01). The area could also be reached (with more
|
|
difficulty) from the "central" plateau area towards <a
|
|
href="76.htm">76</a>, and also via the "Geologists' walk" which passes
|
|
much further left via <a href="171.htm">171</a> and <a
|
|
href="172.htm">172.</a>

<b>Adam Cooper descending to place a bolt below the lip in 1993</b></center>
|
|
|
|
<p>Found in 1993, it was intended to mark the cave but not descend. However
|
|
Adam Cooper's rucksack (containing the rope), placed unwisely near the edge,
|
|
made the first descent. Adam followed on a ladder to retrieve it, then placed
|
|
a bolt for a further descent on rope. The shaft continued beside a snow
|
|
plug, but was deemed unsuitable for further exploration in shorts. The
|
|
find was not relocated in 1993, so exploration stopped. Found again in 1995
|
|
whilst marking other known entrances, and probably seen again in 1996.
|
|
|
|
<p>After a first descent placing a bolt again showed it unsuitable for
|
|
exploration in shorts, a determined effort by Wookey in 1998 pushed the
|
|
second pitch, between hanging death ice and snow to a definite choke.
|
|
However, partway down this pitch was a window with a draught, leading to a
|
|
third pitch (one bolt at takeoff, another just below). This was nn metres to
|
|
a final choke.
|
|
|
|
<p>The whole cave is formed on a fault which forms a SE-facing scarp on the
|
|
surface. A short distance NE of the entrance, the fault line cuts a
|
|
lower-lying area. The draught, which was mostly outward through the head of
|
|
the third pitch during the final exploratory trip, periodically reverses for
|
|
10-15 seconds. It would appear to be powered by surface breezes via various
|
|
other small windows to the surface, most probably including ones lower down
|
|
in the depression to the NE.
