Underground Description
It's a very large entrance, recognisable by the large pyramidal rock. Down a snow/ice slope leads to a ledge (rebelay). There are two ways on, through a small hole, down an icy 13m pitch till it gets too small with ice/rock. The other way is down a 10m frozen waterfall, to a small grotto with large ice crystals,where it all ends. The ice formations may even be worth a tourist trip. (from logbook.)

Notes
Interestingly, the Austrians have this as 1/T +, at 1700m, NE of Schwarzmoossattel, and think it was explored by CUCC in 1984 to a depth of -40m. A photocopy of an annotated copy of the OAV map lying around in the Expo files puts this about halfway between 145 and 147, which makes sense when you think about it.
