<p><b>Altitude</b>: 865m<br>
|
|
|
|
<b>Location</b>: Above Rettenbachtal (north side); about 20-25 minutes
|
|
on foot from Blaa-Alm.
|
|
|
|
<p>A resurgence cave of major importance, visited by CUCC in 1976 and 2002.
|
|
Krenmayr gives it 278m long, seasonally active, very roomy water cave. The
|
|
associated perennial resurgence is Naglbrünndl, putting out 50-100 l/s.
|
|
|
|
<p>Continue past the Blaa-Alm
|
|
hostelry on the track to a crossroads of paths. Take the path to the right and
|
|
then bear downhill and to the left at a fork by a small wooden hut.
|
|
Follow the track until you end up walking parallel to the river; keep a
|
|
lookout on the right for a small bridge across the river. Cross the bridge
|
|
and take a small path to the left, which arrives at a further (smaller!)
|
|
bridge over a stream. Just before the bridge, ascend up the hillside to
|
|
the right through the undergrowth, keeping the large rocky gully to your
|
|
right and the stream to your left. After a few minutes you will arrive
|
|
at the resurgence (under tree-roots) to the left. At this point, cross
|
|
into the gully on the right and climb up to the very top to reach the
|
|
cave.
|
|
|
|
<p>Entrance is at the head of a large, steeply-inclined stream bed (carries
|
|
major flow in flood), and is reminiscent of Sleets Gill. A short climb
|
|
(protection advisable; two hangers in situ; rope of unknown vintage present in
|
|
2002) leads to a tube. This descends at 45° to a short walk round a pool
|
|
to a short greasy climb. One soon emerges in the huge main passage, floored at
|
|
the lower end by vast amounts of very unpleasant mud. The sump is reached by a
|
|
right turn over some fine stratified sand, but CUCC's interest lay in some
|
|
holes in the roof at the top end, with the hope of a high-level continuation.
|
|
|
|
<p>The mud eventually runs out to be replaced by more and more inclined
|
|
slabs, which were very easy on the way up. The gradient steadily increases
|
|
until the floor merges into the end wall, and the trickle of water enters
|
|
from high up. At this point, a couple of holes in the roof have already
|
|
been passed, but investigation revealed these to be beyond reasonable
|
|
reach without some fairly serious bolting.
