The 204a entrance is directly opposite a 10m x 3m stone bridge
from which it derives its name. The entrance itself is approximately 8m high and
5m wide, and leads down a boulder slope and round a right hand bend to the top
of the first pitch. The 204b entrance is 15m away to the west, and this is the
entrance which is rigged.

<p>A 3m climb down (handline useful) leads into the
entrance gully and a ledge at the head of the first pitch, <B>Trick or
Treat</B>, opposite 204a entrance. This loose, sloping pitch of 20m is rigged
from a Y-hang on the right hand wall, with a rebelay and deviation. The pitch is
tedious to prussik on return and is best climbed. The landing is by a large snow
plug with an ice corridor round the edge leading to the top of a
boulder slope. A rift passage on the right becomes too tight.
The snow level varies: in 2000 it was much higher than in 1999, rendering the
original route impassable (see <a href="#1999">here</a>). A revised route was
explored, which was the main route in 2001.
<h3><a name="jim">Second and Third Pitches</h3>
<P>Descending the boulder slope (care required to avoid kicking
rocks off) leads to the head of the second pitch, <B>Jim'll Fix It</B> (18m in 1999 but
only about 10m in 2000/2001 due to increased snow levels). An
unexplored passage is visible from the pitch head, which could be accessed by a
bolt traverse round the right hand side of the pitch head

[<A href="qm.shtml#C1999-204-01" name=qC1999-204-01>C1999-204-01 C</A>] (explored by Brian?).
The pitch is rigged from a bolt in the
left hand wall with a deviation from a spit immediately after the pitch head
bolt. This protects a marginal rub point and also avoids a jet of water which
spurts from a crack in the wall after heavy rain.
The landing is on a large snow plug. Following the wall around to the right (facing the
wall on which the pitch is rigged) leads to a 2m
climb into a rift, which quickly descends to the head of the impressive third pitch,
<b>Stitch This</b> (30m). A Y-hang rebelay on the left wall is shortly
followed by a deviation from the opposite side of the shaft to obtain a free-hang into
<a href="midlevel.shtml#wolp">Wolpertinger Way</a>. This pitch is in fact
an (upwards) continuation of <b><a href="#thread">Thread Pitch</a></b>.
<h3><a name="1999">1999 route to Wolpertinger Way</a></h3>
In 1999, the landing of Jim'll Fix It was by a large
pointed snowplug.
There was sufficient gap between snow and wall to complete the
descent and emerge in a sloping phreatic passage. There are two ways on: Right
leads uphill as stooping/crawling height passage for 30m to emerge at the top of
<A
href="#umshit">Umshitshimbo</A>.
Left leads downhill into <A
href="#nearend">The Near
End</A> and is the main way on. There is a further unexplored passage in the
wall above the gap between the snow plug and the rock [<A

<P><B>The Near End</B> is a collective name for a complex network of high level
phreatic passages which slope approximately 20<32> following the dip of the beds.
Heading downhill from the base of <B>Jim'll Fix It</B> in a stooping height
passage leads round a double bend to a 2m climb down to a junction. Right leads
to more <A
href="#nearside">side
passages</A> whilst the main route is straight ahead to a crossroads. Right
leads into the same <A
href="#nearside">side
passages</A> as the previous right turn. Left is <B>Needle Crawl</B> past an
unexplored passage on the left [<A

straight ahead) which becomes too small after ~8m. Straight ahead (feels like a
left) leads to the head of a fine 4m diameter circular shaft, <B><a name="thread">Thread</a>
Pitch</B>. This pitch of 17m leads into <A
href="midlevel.shtml#wolp">Wolpertinger
Way</A>. A continuation of the
crawl is visible at the opposite side of the pitch head [<A

<P>From the crossroads, the main route in 1999 was straight ahead, downhill in
mostly stooping height passage with a short section of sandy crawling. After 15m
is a short climb down to the top of a 4m deep pit with a too-tight passage at
the bottom, with the phreatic passage continuing to the right. After a further
10m the passage is intersected by a large rift with a big rock partially
blocking the passage. Climbing up to the right leads back into a tall rift in
the <A href="#nearside">side
passages</A>. A climb up to the left leads to a passage containing attractive
white mud which was not entered, however a visual connection to the <A
href="midlevel.shtml#pendulum">Pendulum
Pitch</A> was established.
<P>Straight ahead leads to a further junction after 15m. Left opens out to the
head of <A
href="midlevel.shtml#pendulum">Pendulum
Pitch</A>, the main route to the bottom of <A
href="midlevel.shtml#wolp">Wolpertinger
Way</A> used in 1999. Right leads to a narrow stooping height passage which
continues for 25m with several clear pools in the floor to a widening where most
routes ahead and to the left are choked with boulders. To the right, a body
sized tube leads upwards for ~15m before opening out into a low chamber on the
left. The continuation of the crawl is immediately opposite the entry point and there is a climb down into a rift on
the far side of the chamber to the left [<A
2002-05-26 14:03:59 +01:00
href="qm.shtml#C1999-204-07"
name=qC1999-204-07>C1999-204-07 B</A>]. The continuation is a winding passage which continues upwards. It then increases to stoping
heightand goes over some old gower pools. The passage continues to a flat out section ( not really a squeze, except for lardarses) not
pushed, but running water could be heard. Back in the chamber, it doubles back on itself to
the left and encounters an area of breakdown which was not fully investigated,
but is presumed to be the opposite side of the boulder choke.

<P>The first two right turns encountered when heading downhill from the foot of
<A href="#jim">Jim'll Fix
It</A> unite in a walking sized passage. After 10m the bottom of <A
href="#umshit">Umshitshimbo</A>
is passed on the right, whilst straight ahead leads to a junction with a large
keyhole passage. Left leads after 15m to a climb up behind a precariously placed
boulder, to an immediate climb down of 4m which emerges in the 1999 main route
through the near end before <A
href="midlevel.shtml#pendulum">Pendulum
Pitch</A>. Right leads immediately to a 8m pitch. A difficult and exposed traverse round
the left hand wall leads to a further 30m of passage with a steadily lowering
roof culminating in a boulder choke.
<H3><A name=umshit>The Near End: Umshitshimbo and Updip Passages</A></H3>
<P><B>Umshitshimbo</B> is a fine phreatic ramp, 2m wide and about 4m high, which
heads uphill in a straight line for 40m. At the top a passage doubling back on
the right leads back to the base of <A
href="#jim">Jim'll Fix It</A>
and there is a climb up into a rift passage heading south over the top of
Umshitshimbo which becomes too narrow. Large passage continues uphill past a 2m
deep blind pit on the right to a junction.
<P>Left leads uphill past a choked inlet on the left to a steep uphill section
with a crawl on the right, which leads shortly to a 2m climb down and immediate
choke. At the top of the steep section the passage to the right immediately
chokes, whilst left is <B>Dolly Parton climb</B>, a 2m climb up with huge jugs,
to a further 15m of upward trending phreatic passage, terminating in a boulder
choke with a slight draught (air coming into the cave). There are two small
steep phreatic ramps on the left hand side of this passage, both very small and
both choked.
<P>Straight ahead at the junction leads through a short section of rift to an
enlargement with an alcove on the right and a keyhole passage ahead. The rift
section at the bottom quickly becomes choked, with a slight draught coming in. A
3m climb gains access to the phreatic section which goes over the top of the
choke, and about after a further 3m reaches a large boulder, which almost blocks
the passage with a strong breeze blowing through the gap (into the cave.)
Squeezing through yields a steeply ascending rocky crawl which chokes after
about 5m.
