The rift narrows and bottoms out in a small streamway blocked here and there by jammed boulders which no longer (since 1984) constitute a squeeze. Short traverses and pitches of 15m and 6m are straightforward until a second large shaft is reached. The water cannot be avoided on the 59m Tiddley Pom pitch, which can become a serious proposition in wet weather. The first section is 11m, to the level where a heavy drip (rapidly becoming a torrent in thunderstorms) enters. The rebelay bolt is tucked away to the left, a long reach round the corner. Further sections of 17 and 24m in a circular shaft of about 6m diameter reach a big wet ledge. The final section of 7m reaches a big dry stance on jammed boulders, Cold Toes Ledge. This is far enough out of the water to be an acceptable place to sit and wait for 16 hours, or to brew soup.
The stream continues to drop in a rift, with pitches of 13 and 14m from jammed boulders. The water then sinks into a slit, Nobody Knows, which was descended for 15m before becoming too tight. To continue, traverse over this hole and continue a short way to a large black chasm, the 112m Fear and Loathing Pitch, involving some airy traversing near the top. Sections of 10, 29 and 16m reach Acrobat Flake, where careful rigging is required to avoid a particularly gymnastic changeover for the next section of 16m. The rift (never wider than 3-4m) continues with drops of 18 and 23m to land on an unpleasant bit of damp floor: Las Vegas.
A particularly unpleasant mud-walled rift, Beezley Street, ("where the rats have rickets") continues as a traverse if you can stay up, or a nasty thrutch otherwise. This ends abruptly where an aven brings clean washed limestone for the next 14m pitch. A clean, but sharp traverse continues to corkscrewing 18 and 5m pitches into The Drainage Ditch, a wading depth section of passage occasionally blocked by boulders, which hold back the static pools. Short pitches of 8, 9 and 7m twist down to another section of drainage ditch which continues for a few more metres to a static sump 399m below the main entrance.
A hole above the sump leads to a small, muddy, grovelly continuation to some small avens and a further sump, before closing down.
Geology : Tubes near the entrance are formed along the prominent NE-SW joint direction in the area, which so dominates the nearby Bräuninghöhle, and the cave trends generally SW as it drops. However, all the major vertical development is in deep shafts on joints at right-angles to this major trend, on a strike of about 120-300°. Fear and Loathing pitch in particular is in a strikingly narrow rift over 110m deep, suggesting an almost vertical joint. Below this shaft there is very little significant jointing, and the cave meanders considerably before the dismal end another 140m SW.
There is enough survey bumph to draw a respectable plan.
Entrance is 2m high and 1m wide and walking passage leads for 120m of level going to first pitch, with a few side passages (one to higher entrance). Pitch is 19m into Wolf Chamber where the skeleton proved not to be of a wolf but of a Brown Bear, Ursus arctos. A pit in the floor, the Bear Pit is blind, and the continuation of the entrance pitch emits no draught and is believed to choke, but was never seriously investigated. A loose 3m climb at the far end of the chamber leads up into a draughting tube. This leads to an awkward 15m slimy tube descent, Bog Seat Climb, best laddered. A short grovel enlarges to a sandy stooping passage which pops out over the edge of a large black hole. Off to the left at this point a crawl intersects a larger passage leading to another set of smaller shafts only partially descended. It is also possible to reach the opposite side of the big pitch by this route.

There is a particularly inadequate elevation only in Cambridge Underground 1985. There is an area plan, drawn at 1:2000, showing 145, 82 and 148 on Gauß and Krüger coordinates, which has never been published.
There is enough survey bumph to draw a respectable plan.
Back at the boulder slope (I think), the 20m pitch can again be attained and from here is 15m to the floor of a 20m high chamber with three ways on. Facing away from pitch, righthand rift leads to a flat-out crawl over ice. This passes remarkable ice formations to emerge at The Ice Castle, a chamber with a large ice-stalagmite formation. The route terminates in a steep ice slope at the far side of the chamber.
Way directly ahead from pitch is a 3m climb into a large phreatic tube round a 90° bend to a solid wall of boulders. Ways into the choke proved very loose and tight, but a continuing rift/chamber could be seen through a tiny but strongly draughting hole.
Third way on from pitch ascends steeply and becomes tight, with a jammed boulder now in the way. Route ends at a steep ice-climb for which no equipment was available.

In 1993 the cave was "extremely cold and some ice formations".
In 1993 the cave was "extremely cold and some ice formations".
This has a 5-6 second booming clattering drop, and had a very poor quality spit at the top. It was not descended in 1995. This may be the cave referred to in the description of 165, located by CUCC in 1989, but already having a bolt, and not descended by CUCC but with "a drop in excess of 35m". 2000 descent reached floor at 37m down, with the only way on a small hole that turned out to be too tight. -

Elevation never drawn up; see notes in 2000#04
