Underground Description

The main entrance is rigged off a spit and naturals and drops around 8m, via a natural deviation at a ledge, to a small chamber. A crawl leads off from here at head height for some distance, but closes off. The way on is to continue straight down through the floor of this chamber, through fairly solidly wedged boulders (quite tight) using the rope rigged on the entrance pitch. This lands at the head of a walking sized rift heading steeply down. There are two small passages in the wall where the rope comes down [these connect to the horizontal entrance of Nordalpenhöhle, see below]. Clamber down the rift. At the bottom is the snow plug from the second entrance. It is possible to cross the snow plug. At the far side, the passage closes down and is mud filled with no draught.

The way on is a flat-out crawl under the right wall, immediately before the snow plug. The crawl was dug because it was draughting out quite strongly. Once under the wall, the roof immediately rises to comfortable crawling height and the passage widens. After 5m, roomy phreatic passage is reached, around 5m wide and 3m high. A roof tube leads off to the right. It can also be reached by a roof crawl from further down the passage on the left. The tube leads to two small chambers and ends in a too-tight rift.

The floor of the main passage starts to drop away as the passage turns to the right, leaving a ledge along the left wall. A trickle of water enters at floor level. A pitch is rigged off the ledge using spits in the left wall. This pitch drops 10m and ends in a choked chamber. An exposed traverse on the left, beyond the pitch head, leads to a choked tube. Directly across from the pitch head, a further roof tube also chokes.

The third horizontal entrance begins with a flat out crawl in sticky mud, and reaches a small, low chamber. The low passage continues as hands and knees crawling. This passes a window on the left which looks into the snow-filled shaft (the second entrance). Straight ahead and a little further, an eyehole looks into the chamber which the first entrance pitch lands in. Continuing on, straddling over a rock ridge leads to two further eyeholes which look into the sloping rift passage where the rope ends from the first entrance pitch.

Survey

1996-9 NotKH book pages 76-77. There are two sets of surveys: larger-scale drawings of the main passages, and less detailed sketches including the horizontal Nordalpenhöhle entrance. These are all very bad scans, as the originals are on very thin paper, and can't easily be removed from the NotKH book without damaging them.
