Altitude: c 1600m
Depth: 105m.
Marking: number painted red in 1976, refreshed (probably in orange which elsewhere hasn't lasted well) in 1990.
Location: In grassy pasture east of Bräuning Alm, next to CUCC's high-level camp of 1977 (camp 1).

Open shaft of 15m leads to a descending rift. Next pitch of 25m, then a short climb, 6m pitch and 15m pitch into a chamber where the water sinks. The upper level of a small rift leads to an abandoned passage and a series of increasingly muddy freeclimbs to a final squeeze and 5m pitch into a sordid little sump.

Exploration: CUCC 1977 - Team Enthusiast.
