Altitude: 1633m, depth ~12m
Position: E 35599 N 82909 (tag at 101)
(GPS: (cliff directly above 101A) GK 5410503 5283483 (FOM 9.2m))
Bearings: Bräuning Scharte 218°, Grieskogel 012.5°, Bräuning Nase 194.5°, Lost Rucksack cairn 319° (compass #439258: NPC2)
Marking: extremely faded numbers "101" and "101A" in red on upper and lower entrances. 1998 tag "1623 101 CUCC 1977" on upper entrance, southeast-facing (M6 stud).

Location: Out on the plateau, near a large north-facing fault scarp on 125-305°. Perhaps best located when looking for Wolfhöhle (which is nowhere nearby) in the mist (see 1984 logbook). There was an OAV ski-tourers' marker pole due north of the col, from which the entrance is about 50m away on 35°. Unfortunately, the pole was pretty much invisible from the approach route in 1977, and is now rotting on the ground, only visible from a metre away at best. However, the cave was relocated in 1998. It turns out to be very close to the faintly-marked path which leads past Lost Rucksack Cave towards CUCC 1996-05, and is a short way south of 1623/173.

Entrance is in a rift orientated 40°-220° and hading about 20°. A 5m climb down leads to a horizontal passage going both ways, north leading out into the face of the scarp (101A). South (down dip) leads to a 4m pitch followed by a small crawl in a scree-floored phreatic tube, leading down dip, at about 30°. This drops via a short climb into a meandering phreatic tube with a tiny stream slot fed by an aven on the left. Progress is by crawling in the roof tube, which goes for about 40m until a window in the right wall leads to the base of an aven. The continuing crawl is too small, while a climb down below the aven (undescended) appears to choke.
