<underground_description>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 <b>Wolf Chamber</b> where the skeleton proved not to be of a wolf but of a Brown Bear, <i>Ursus arctos</i>. A pit in the floor, the <b>Bear Pit</b> 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, <b>Bog Seat Climb</b>, 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.</p><p>The 83m <b>Big Leap</b> is rigged in three sections of 22, 25 and 36m via two freehanging rebelays and a deviation near the bottom, in a large rift with black peaty mud on the walls in the upper section. 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 <b>Tiddley Pom pitch</b>, 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, <b>Cold Toes Ledge</b>. This is far enough out of the water to be an acceptable place to sit and wait for 16 hours, or to brew soup.</p><p>The stream continues to drop in a rift, with pitches of 13 and 14m from jammed boulders. The water then sinks into a slit, <b>Nobody Knows</b>, 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 <b>Fear and Loathing Pitch</b>, involving some airy traversing near the top. Sections of 10, 29 and 16m reach <b>Acrobat Flake</b>, 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:<b> Las Vegas</b>.</p><p>A particularly unpleasant mud-walled rift, <b>Beezley Street</b>, ("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 <b>The Drainage Ditch</b>, 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.</p><p>A hole above the sump leads to a small, muddy, grovelly continuation to some small avens and a further sump, before closing down.</p><p><b>Geology :</b> Tubes near the entrance are formed along the prominent NE-SW joint direction in the area, which so dominates the nearby <ahref="../82.htm">Bräuninghöhle</a>, 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 anoth
