<approach>From <ahref="/1623/164/164.htm">164</a>, avoid <ahref="/1623/189/189.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 Lärchen), passing right of the OAV ski marker pole. This is an easy walk above a short (climbable) cliff looking down onto <ahref="/1623/210/210.htm">210</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 <ahref="/1623/173/173.html">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 <ahref="76/76.html">76</a>, and also via the "Geologists' walk" which passes much further left via <ahref="171/171.html">171</a> and <ahref="/1623/172/172.htm">172.</a></approach>
