Underground Description
Not really pushed in 1984, since discovered right at the end, but relocated in 1987: horizontal tube entrance about 1m in diameter. An awkward crawl over boulders for 10m leads to a squeeze down behind a boulder with light entering ahead. Short freeclimb reaches a phreatic tube of about 3m diameter. To the right silts up in boulders while to the left descends gently over snow and big rocks to reach a sizeable chamber and pitch of about 20m. Avoiding the pitch, a route down through boulders for 3m reaches a very unstable boulder slope, which is crossed to reach another 3m pitch to a rift with a further pitch on the left. To the right, the roof lowers over large boulders, and a small ice chamber is reached with a frozen stream. A narrow section leads down to a rift of 5m down to an earthy passage.Back at the boulder slope (I think), the 20m pitch can again be attained and from here is 15m to the floor of a 20m high chamber with three ways on. Facing away from pitch, righthand rift leads to a flat-out crawl over ice. This passes remarkable ice formations to emerge at The Ice Castle, a chamber with a large ice-stalagmite formation. The route terminates in a steep ice slope at the far side of the chamber.
Way directly ahead from pitch is a 3m climb into a large phreatic tube round a 90° bend to a solid wall of boulders. Ways into the choke proved very loose and tight, but a continuing rift/chamber could be seen through a tiny but strongly draughting hole.
Third way on from pitch ascends steeply and becomes tight, with a jammed boulder now in the way. Route ends at a steep ice-climb for which no equipment was available.
