<p><b>Altitude</b>: 865m<br>
<b>Location</b>: Above Rettenbachtal (north side).<br>
Easily reached on foot from Blaa-Alm, even when drunk
<p>A resurgence cave of major importance, visited by CUCC in 1976. Krenmayr
gives it 278m long, seasonally active, very roomy water cave. The associated
perennial resurgence is Naglbr&uuml;nndl, putting out 50-100 l/s.
<b>Location</b>: Above Rettenbachtal (north side); about 20-25 minutes
on foot from Blaa-Alm.
<p>Entrance is at the head of a large stream bed (carries major flow in
flood), and is reminiscent of Sleets Gill. The tube descends at 60&deg; 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>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 Naglbr&uuml;nndl, 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&deg; 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
