<h1>Big Boulders area</h1>
|
|
|
|
<p><b>Summary</b>: The Big Boulders area is dominated by a large breakdown
|
|
chamber and contains a number of unexplored leads. It is accessed from the
|
|
<a href="pussyprance.html#prowl">On the Prowl</a> traverse in the Pussy
|
|
Prance area.</p>
|
|
|
|
<h3><a name="dogdays">Dog days</a></h3>
|
|
|
|
<p>In the southwest corner of the chamber reached from the end
|
|
of Puss in Bolts is a 3m pitch. Traversing over this pitch
|
|
(rope required) leads into a rift passage. The narrow
|
|
continuation of the rift ahead is unexplored [C2012-204-XX B],
|
|
but a 3m climb up on the left (bolts placed for a rope) leads
|
|
into Dog Days. Comfortable walking passage heads south for 20m,
|
|
past a roof tube on the right and via a 3m climb down, to a
|
|
complex junction. There are two unexplored passages on the left
|
|
at this point ([C2012-204-XX B] and [C2012-204-XX C]).
|
|
[FIXME: (Olly/Becka/Andrew) lots of bits here that AD can't remember/knows
|
|
nothing about].</p>
|
|
|
|
<p>The way on is a muddy passage which quickly leads to the
|
|
head of an 18m pitch overlooking a large space. Descending
|
|
this pitch lands in <a href="#bigboulder">Big Boulder
|
|
Chamber</a>.</p>
|
|
|
|
<h3><a name="bigboulder">Big Boulder Chamber</a></h3>
|
|
|
|
<p>As its name suggests, Big Boulder Chamber is a large
|
|
breakdown chamber containing many huge boulders.
|
|
[FIXME: (Andrew/Becka/Julian/Stuart) survey shows QM C downhill from landing point].
|
|
From the point at which the rope lands, the way on is
|
|
up an unstable rubble slope to the north (care required).
|
|
[FIXME: (Andrew/Becak/Julian/Stuart) uncertain about the exact route here - lots of
|
|
bits on the survey to the east that AD knows nothing about]
|
|
The route continues north through breakdown until a
|
|
climb beneath a large boulder on the left leads to a
|
|
boulder slope which can be descended with care to a
|
|
continuing passage to the north. Shortly beyond the
|
|
bottom of the boulder slope, a passage on the right
|
|
leads, past a narrow unexplored passage on the right
|
|
[C2012-204-XX C] to a muddy, exposed climb up into a possible
|
|
phreatic passage with a sound of water [C2012-204-XX B].</p>
|
|
|
|
<p>The main route continues north in comfortable sized passage
|
|
with a draught from south to north. After 10m, a wet aven is
|
|
reached on the left [C2012-204-XX X] with a 3m pit beneath
|
|
with a narrow rift exiting [C2012-204-XX C]. The continuing
|
|
passage gradually narrows and continues for a further 40m to
|
|
a T-junction where <a href="#pretzel">Pretzel passage</a>
|
|
leads off to the left and right.</p>
|
|
|
|
<h3><a name="pretzel">Pretzel Passage</a></h3>
|
|
|
|
<p>Turning right at the T-junction leads immediately to
|
|
a local widening with three ways on. West leads immediately
|
|
back to the passage from Big Boulder Chamber near the
|
|
T-junction. North is a 2m climb and east is a low passage,
|
|
both of which ultimately lead to the same place. The easiest
|
|
route is to take the low passage to the east.
|
|
This quickly opens out to a comfortable sized sandy passage
|
|
which proceeds, past a climb up to a narrow passage on the
|
|
right [C2012-204-XX C], before the roof lowers again. 10m
|
|
further on the roof rises at the base of a 3m climb up on the
|
|
left. <i>Up the 3m climb leads to 15m of narrow, sandy,
|
|
walking sized passage emerging at the top of the 2m climb at
|
|
the start of the passage.</i>. Comfortable sized walking passage
|
|
continues north for 10m before turning northwest and descending
|
|
gently to the head of an undescended pitch with the sound of
|
|
water [C2012-204-XX A]. The pitch is at least 15m across and
|
|
stones rattle for at least 8 seconds. There is a draught blowing
|
|
from the pitch towards the known cave.</p>
|
|
|
|
<p>Turning left at the T junction, a sandy slope down to the
|
|
right is quickly reached (rope required for a safe descent) with
|
|
a passage heading off at the bottom [C2012-204-XX A]. Traversing
|
|
across the top of the slope leads to a further passage with an
|
|
immediate junction. Left is a steeply ascending passage which
|
|
requires protection [C2012-204-XX B]. Ahead, comfortable passage
|
|
continues for 8m to a sand choke, with a small continuation
|
|
to the left with no draught [C2012-204-XX C]. Right leads, via a
|
|
2m climb up, to a muddy rift. This passage proceeds for 30m
|
|
reaching the head of an undescended pitch that is at least 20m
|
|
across [C2012-204-XX A]. This pitch is 40m away from the pitch
|
|
at the end of the other branch of Pretzel Passage, and has a
|
|
similar character. There is a draught heading towards this
|
|
pitch. A climb up on the right at the pitch head gains access
|
|
to a roof tube [C2012-204-XX C].</p>
