<underground_description>A vertical entrance which leads, at a depth of -145m, into <ahref="113.htm">Sonnenstrahlhöhle</a> below the Purple Pit, just before Müsli crawl (-198m from Sonnenstrahl entrance bolt). Entrance pitch <b>Scott</b> is 9m over snow, then a small tube leads down to a short climb down boulders to an 8m pitch <b>Virgil</b>, followed immediately by <b>Alan</b>, another 8m pitch landing in <b>Dump Chamber</b>. A long rift, <b>Boulder Alley</b> leads to a rock bridge and scramble down boulders into <b>Boulder Chamber</b> which ends in a 4m climb and pitches of 5m (<b>John</b>) and 4m (<b>Parker</b>) over boulders. A 5m pitch (<b>Mr. Tracy</b>) drops into the top of a very tall narrow rift. A slight widening allows a short climb down into the canyon, but is soon too tight - <b>Lady Penelope</b>. The rift continues until a fault is met and <b>The Good Pitch Venus</b> is 24m to <b>Behind the Drinks Cabinet</b>. A further rift leads to a 16m pitch which lands in Sonnenstrahlhöhle.</p><p>Boulder Chamber appears to correspond with the bouldery Opera House in Sonnenstrahlhöhle, while the Good Pitch Venus and following 16m pitch correlate with the Purple Pit.</underground_description>
