Altitude: 1640m, depth 35m
Position: E N
Marking: numbered in red (1977) on scarp facing south, 1998 tag "1623 93 CUCC 1977".

Location: Plateau - below Bräuning Scharte, north of Kataster 91.

Approach: From Schwarzmoossattel, follow cairned path below the Bräuning Wall, past Top Camp (1988 on). Where this path meets the scree/snow slope from the wall, it turns right, out onto the plateau (this is the main path to Gschwandt-Alm, in frequent use).

100m from the right turn is a snow field on the right, with the sound of falling water at its lower edge. This is the entrance to 91 and from here, 93 is 20m further away from the Bräuning Wall.

Entrance 91 on left, looking towards 93 and Schönberg

Long rift on a joint (strike 246°, dip 70° towards SE) ending in choke at -35m. An adjacent shaft on the same joint but further east is bigger and more obvious, but chokes much nearer the surface.
