A contortion through boulders leads to a large horizontal passage, which gradually ascends until eventually lowering to a short flat-out crawl over choss. This leads to a chamber, from where it is possible to slither to the left through a gap between choss and the ceiling. Here there are two ways on. To the right ends quickly; a dig under the wall ended in a further choke. To the left leads to a tight crawl through dangerous boulders which would need digging to make further progress.A noticable draught outwards is present throughout the cave.
