Altitude: 1680m
Location: Just south of Schwarzmoossattel, in the far upper reaches of Kratzertal. There is an obvious freeclimbable shaft/cave just down valley from the equally obvious shakehole/shaft labelled B4. It is numbered twice, once very faded and once very badly run (last seen 1996): both numbers are needed to deduce (with difficulty) that this is indeed "75".

This entrance connects with a second shaft just down valley. The Austrian article describing the cave says it is about 60m long, but this did not appear to be the case in 1990, since it seems to choke very quickly - perhaps digging would now be required to get in.

Exploration: Edith Bednarik, 1977
