<p>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 204a entrance is 15m away to the west.
|
|
|
|
<p>From 1999 until 2001 inclusive, the 204b entrance was rigged. However,
|
|
this involved a rather shoddy decent down a gully, and so from 2002
|
|
the 204a entrance has been used.

|
|
The 204a entrance leads, via a short climb down, to a ledge overlooking
|
|
the first pitch, <B>Trick or Treat</B>. This is rigged with a traverse line
|
|
and a Y-hang in the roof, giving a superb and very airy free-hang to the
|
|
bottom.
|
|
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 onward impassable (see <a href="#1999">here</a>). A revised
|
|
route was explored, which was the main route in 2001.</p>
|
|
|
|
<h3><a name="jim">Second and Third Pitches</a></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.</p>
|
|
|
|
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>.

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 href="qm.shtml#C1999-204-03" name=qC1999-204-03>C1999-204-03 C</a>].

<b>The Near End</B> is a collective name for a complex network of high level phreatic passages which slope approximately 20° 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 href="qm.shtml#C1999-204-04" name=qC1999-204-04>C1999-204-04 C</A>] and a crawl on the right (feels like 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 href="qm.shtml#C1999-204-06" name=qC1999-204-06>C1999-204-06 C</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. Around the widening, most routes ahead and to the left are choked with boulders. There are two ways on: down over a few boulders leds to the previously concealed short pitch called <B>'king carbide</B>, while on the right a body sized tube leads upwards for ~15m before twisting left into a low chamber 'Kidneybean'. Kidneybean, perhaps an enlarged bedding plane, has possible QMs in a hole in the floor [<A href="qm.shtml#C2000-204-71" name=qC2000-204-71>C2000-204-71 C</A>] and in a narrow passage at the nothern corner of the chamber [<A href="qm.shtml#C2000-204-70" name=qC2000-204-70>C2000-204-70 B</A>]. Round to the left it is bounded by an area of breakdown, possibly the far side of a boulder choke visible from the widening. Back at the entrance Kidneybean, the main way on continues through a low gap. This opens to stooping height and winds upwards. The passage continues over some old gower pools to a flat out section (not really a squeze, except for lardarses) not pushed, but running water could be heard [<A href="qm.shtml#C2000-204-69" name=qC2000-204-69>C2000-204-69 A</A>].

<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.
