Altitude: 1600m
Location: in Kratzer valley, down valley from Fledermaushöhle (Kat. 71), on true right some way above bottom of valley. In the same entrance doline as Dr.Kerschner Höhle (Kat.35).

Sounds like a free-climb to a snow choke (very much like B5, which must be in virtually the same place ?)
