<underground_description>The first pitch starts after a short climb down boulders. From here light may be seen entering from another entrance 143b. The pitch of 20m lands on a small ledge and a short freeclimb leads to a traverse over wedged blocks. The next pitch of 10m is rigged over the edge of the last of these and brings one to a balcony at the start of a 23m shaft. Another clean, almost circular shaft (19m) follows, to a climb of 6m down wedged boulders. The passage now narrows to a small vadose canyon with a stream in it, but soon turns vertical at an 8m pitch, followed quickly by one of 18m. At the foot of this final shaft, the stream flows down a rift, approximately 10m deep, but too narrow to follow. Much hammering here achieved little progress, but could be heard clearly in passages leading from above the Big Pitch in <ahref="41/41.htm#bigpitch">Stellerweghöhle</a>.</underground_description>
