Location: At the south foot of Loser (visible from Altaussee). Reached by traversing west from the Loser path as it draws level with the cliffs.

The round 8m wide by 10m high entrance leads into an upper level, the Hauptgang, leading north then northeast to Regenhalle, a sizeable chamber apparently formed on a significant SW-NE joint. Immediately right at the start of the chamber, a boulder slope leads up into Teilungshalle, from where a wider slope drops left back into Regenhalle about halfway along. At the highest point of Teilungshalle, a SE-going passage quickly chokes with boulders, but appears to be heading directly for the end of Kleines Loserloch, perhaps 10m away.

Keeping to the right (SW) wall entering Teilungshalle, a rift leads SW. A passage left after 5m quickly ends too tight. A traverse to the left hand side bypasses a 5m shaft in the floor. 15m beyond, another lead on the left leads up into a small chamber, Kapelle. The continuing rift, Südwest-Kluft, gets narrower for c 25m until deemed impassable.

Back in Regenhalle, a narrow section along the joint between the two ways to Teilungshalle, gives access to a lower series via a sharp turn to the right, due south. This wide passage, Südwest-gang, passes under Teilungshalle, and turns SW directly under Südwest-Kluft. A narrow rift on the left parallels the main passage for some way. The main way develops into Gr. Dom, 12m wide, with a boulder slope up until the passage chokes comprehensively on a broad front, almost exactly below the cliff outside.

At the far (NE) end of Regenhalle, stright on enters a draughting boulder choke, but two ways up to the right lead into Stufengang, with a complex of little rifts and an extension NE to a low choked area.
