<p>Beyond the stoop is a 3m climb down in a rift below an aven, which
can be climbed far enough to see that it probably doesn't go. At the bottom
is wide stony passage with obvious ways off to West and North. There
is a handy water-filling pool here.</p>
<p>West, there is a stepped pitch down to the left [2007-258-01-A], and a 3m climb up to the right of this (rope needed) leads into a strongly draughting passage which gaoes about 50m to the edge of a large round pitch[2007-258-02-A]. A continuation [2007-258-03-B] can be seen 15m away across the far side.</p>

<p>North (from the water-filling pool) a 2m climb up rotten calcite leads (past [2007-258-04-A], LHW) to an unusual
critical-angle pile of 10cm diameter rocks <strong>Y KeyKey Beach</strong>.
The narrowing at the top of this pile
(it gets close to the roof) has a stonking gale coming through it. Just
beyond this where the passage widens to 8m, behind the large rock on the left
is the hidden entrance to <strong>Rhubarb Crumbly</strong>, the key to the
<strong>Max Pleasure</strong> area. On the right, at the widening, is
a shallow pit [2007-258-05-C].</p>
<p>Ahead the comfortable passage only goes for about 20m before reaching the edge of a huge shaft undercutting the RH wall[2007-258-04-A]. An airy traverse to the left of this reaches another hole on the left down, apparently into the same pitch[2007-258-05-A]. Immediately ahead is another large hole [2007-258-06-A]. There appears to be a continuation across the other side - a long bolted traverse away[2007-258-07-C].</p>

<h3>Rhubarb Crumbly</h3>
<p>Climbing down behind a large rock in Littoral North gives access to nice walking passage floored with dark dirt.
<p>Climbing down behind a large rock in Littoral North gives access to nice
walking passage floored with dark dirt, trending NNW. A strong breeze
blows in. After 40m the passage passes over a cross-joint forming a
pitch that can be seen through a very small hole in the floor. Would
need capping to get in. Immediately beyond a C2 gets into almost
perfectly straight passage with some popcord on the walls. At the end
is a wider T-junction. Down to the left is a stoop into a
boulder-floored chamber containing a too-tight crawl on the left and
two small avens [2007-258-11-X] (at 1st corner), [2007-258-12-X] (at
end). To the right is another T-junction only 5m further on. Right is
Max Pleasure. Left is Dubious Pleasure, down which all the draft goes.</p>
<h2>Dubious Pleasure</h2>
[Description Needed - Jon Telling or Morwen]
<h2>Max Pleasure</h2>
<p>High chamber merges back into walking passage. 10m along a soil slope comes in from the right wall, choked to the left, and a low crawl [2007-258-08-B] to the right. The passage slopes gently down until it meets a larger one with the way on going gently up-dip to the right. There is a large boulder at the junction. The continuation of the larger passage on the left is choked with soil.</p>
<p>Fine walking passage heading steadily up-dip. Strong outward draft.
Goes 180m to Starfish junction, via a few boulders to clamber over.
After 130m a shelf forms on LH wall after floor canyon disappears
under LH wall. The shelf is the main way on and rises slowly above
floor level until you are traversing past a large hole on the R. This
connects under RH wall to [passage name needed]. Crawls
on LH side at shelf level 30m south of Starfish Junction have
[2007-258-13-C] parallel to main passage and [2007-258-14-B] in back
corner behind pillars. [2007-258-15-B] is a climb up on L in
cross-rift 10m south of Starfish Junction. [2007-258-16-X] is a high
(20m+) aven at the same point.</p>
<p>Past a pillar the passage opens up into a high wide chamber with a deep canyon in the floor, largely covered by boulders. At the start of the chamber a rapidly-lowering passage goes back right for 8m before being choked with sand. At the far end of the chamber you step over the canyon [2007-258-09-A] and have to clamber over some very nice flowstone to proceed. The obvious way on is walking passage but in fact the passage goes at two levels here - you can also climb down below the flowstoned chockstone and follow the canyon upstream to get to the same chamber.</p>
<p>Starfish Junction has 4 large passages meeting at a large boulder and
is a distinctive spot. Ahead (North) Max Pleasure continues, The
right fork is <string>Flying High</strong>. The 4th passage is
[passage name needed]. Including the higher and lower-level
connections this is a complex junction.</p>
<p>Following the obvious higher level brings you into another chamber with a deep hole in the floor [2007-258-10-A] , mostly blocked by a large jammed boulder. Traversing around the left hand side reaches a 3m climb down to the far side of the hole. This is <strong>Petticoat Junction</strong> where there is a choice of left towards <strong>Let's get Naked</strong> or ahead across rocks and uphill to <strong>Hedonism Highway</strong>.</p>
<p>Max Pleasure north of Starfish Junction initially opens into a
High chamber with a drafting (inwards) passage off on the L [name?].
The chamber merges back into walking passage after 40m. 10m along a
soil slope comes in from the right wall, choked to the left, and a
low crawl [2007-258-17-B] to the right. The passage slopes gently
down until it meets a larger one with the way on going gently up-dip
to the right. There is a large boulder at the junction. The
continuation of the larger passage on the left is choked with soil.</p>
<p>Past a pillar the passage opens up into a high wide chamber with a deep
canyon in the floor, largely covered by boulders. At the start of the
chamber a rapidly-lowering passage goes back right for 8m before
being choked with sand. At the far end of the chamber you step over
the canyon [2007-258-18-A] and have to clamber over some very nice
flowstone to proceed. The obvious way on is walking passage but in
fact the passage goes at two levels here - you can also climb down
below the flowstoned chockstone and follow the canyon
upstream to get to the same chamber.</p>
<p>Following the obvious higher level brings you into another chamber with a
deep hole in the floor [2007-258-19-A] , mostly blocked by a large
jammed boulder. Traversing around the left hand side reaches a 3m
climb down to the far side of the hole. This is <strong>Petticoat Junction</strong> where there
is a choice of left towards <strong>Let's get Naked</strong> or ahead across
rocks and uphill to <strong>Hedonism Highway</strong>.</p>
<h2>Hedonism Highway</h2>
Very high rocky passage uphill with monster draft (considering passage size) blowing out. This whole passage is formed on a bedding plane sloping at about 25 degrees from horizontal, so everywhere is walkable but quite steeply sloping. A tricky c2 over a block reaches a sandy hading chamber. Going across to the left reaches a very wide, bedding-aligned area with a choice of routes upwards either side of a pillar. [2007-258-11-A] is a passage off to the left. At the top of the wide bit the passage reverts to a phreas with a deep canyon which is largely inaccessibly-narrow. It is at least 8m deep and there are a couple of points one could get in [2007-258-12-C].</p>
<p>Climbing over a large boulder the passage widens due to a junction. The passage goes off left upwards [2007-258-13-A], as does the canyon, and another goes off left downwards [2007-258-14-A]. The passage continues steeply up-dip and gets bouldery. There are a couple of huge dropped sections of rock that have been undercut and split from the roof. On the left is a small alcove passage. Next a small cross-passage roof tube. Neither of these go. The draught remains strong, blowing out. The passage turns 90 left to go along the dip. A strongly draughting small passage comes in fro the right at the corner. Hedonism highway gets boulderier and closes down over the next 60m. This point may be quite close to the surface.</p>

<p>Climbing over a large boulder the passage widens due to a junction. The

<p>Taking the smaller northerly passage at Petticoat Junction leads
into passage of varying character. It starts with deep dark soily
deposits. Awkward small passage on L connects back to the climb just
before Petticoat Junction. The draught is still strong and inwards.
Crossing a soily crater leads to a sloping c3 up a wide, high
rift, then along 10m of narrow joint-controlled passage to another
sudden change of character. Ahead is a tight passage which draughts out and
becomes a dig after 10m [2007-258-24-D]. The way on is the very wide
phreatic passage sloping steeply down to the east. The small central
canyon of this passage goes under the RH wall to the west [2007-258-25-C].</p>
<p>The passage zigs and zags sharply past a crawl off on the L
[2007-258-26-C] for 20m to merge into nice straight passage sloping
gently down-dip. After 35m it steepens and a small canyon forms,
reaching a 3m deep drippy pot after another 25m. A c2 gets to the
floor and a delicate and slightly damp c3 gets back into the
continuing passage.</p>
<p>Here the passage is wide and sandy and forks: off on the right is
<strong>Let's get Naked</strong> (draughting out). Down to the left
it descends steeply and crossword passage goes off on the Left. 10m
beyond is [2007-258-27-C] on the L then a gravelly bit with an aven
above [2007-258-28-X]. The passage continues to descend down-dip
until it suddenly chokes (3m dia!) with mud and rocks. This would be
a top dig site in the UK [2007-258-29-D]. On the L is a large (8m
dia?) chibble-floored pothole which can also be overlooked from a
balcony, reached via a passage on the L; that passage has a small QM
[2007-258-30-C]. On the far side of the hole a crawl heads off,
unsurveyed, continuing down-dip for quite some distance (30m?)
hole</p>
<h2>Crossword Passage</h2>
High canyon passage initially rises gently then up more steeply.
There is a hole in the roof [2007-258-31-X] here. Now progress is
either a traverse to look out over a pitch past a huge wedged
boulder, or progress at floor-level to look out below the boulder.
Probably about a P12 [2007-258-32-B]. This passage draughts in.
<h2>Let's get Naked</h2>
Very sandy, low, wide passage curves round to the R. [2007-258-33-C]
goes off to L at lowest point. Clambering up over boulders with
freezing draught in your face (out of cave) reaches a aven, which we
partially climbed and it appears not to go, but there seems to be a
drauft defecit beyond. Ahead the passage rapidly shrinks to a narrow
rift which can be climbed (c4). [Let's get naked continues...]
