< p > The shaft of the 258b entrance, rigged with an initial belay, deviation and
Y-hang just below the lip,
gives onto the main entrance shaft just above a single bolt rebelay also
accessible from the 258a entrance. A hang of around 10 metres from this
single bolt lands on a flat
floor where there is sometimes a snow plug. (The 258a entrance, no longer
used, was rigged with a thread in the bottom of the shakehole and a bolt
on the left wall under the dripline. This enabled a descent of several
metres to a small ledge, where working around to the right gained a rebelay,
succeeded by the single bolt rebelay mentioned above.)
A bolt on the left
wall (looking down the pitch) may be used to reanchor the rope here.
Upslope leads to an alcove. The rear of this alcove opens onto the
top of a pitch that appears to be of quite some depth [2006-258-1-B] which
may connect with Stone Monkey below.
< p > Following the left wall, a traverse
leads to a low bolt, which is succeeded by a scruffy descent of only
two metres to another rebelay on a flat wall. The descent continues down
the side, or on top of, a large snow plug to a lip where two bolts in the
ceiling (ring hangers essential) provide a high Y-belay for the next stage
of the pitch. (The original route used in 2006 did not use this Y-belay,
and instead descended via an undercut rift to the left known as The Col.)
A deviation helps slightly to alleviate rope rub on the lip
and is succeeded by a further ledge. There is sometimes a snow plug here,
and upslope, a rift leads off (under The Col) which could maybe lead to
further passage [2006-258-3-B].
< p > The rope is rebelayed at the ledge, and
after a further rebelay from a nose, drops for a few metres to the head of
a large snow slope. The descent is continued from the same belay all the
way to the bottom of the slope. There is a possible way on to the
side of the snow plug on the left wall [2006-258-4-C]. Passing under
an arch the slope terminates with ice stalactites in alcoves to either side and
(depending on the year) an ice lake or pile of snow. The ice stal in
the alcove to the left could be ascended with ice and/or climbing equipment
to reach a passage [2006-258-5-C].
< p > [Description needed 2006-258-2-B is missing - Dave Loeffler or Aaron Curtis or Mark Shinwell]< / p >
< h2 > To the main cave< / h2 >
< p > The main way on from the bottom of the snow slope
is a hole at floor level that leads
into a chamber. This chamber is on occasion occupied by a large ice
stalactite and accompanying ice floor.
A small hole to the right gives access to
< b > Bauernkrapfen Passage< / b > , a well-formed sloping crawl debouching
into a large rift
chamber, < b > Three Fried Mice< / b > .
Following the chamber around to the left
2006-09-07 03:26:40 +01:00
leads to a choke at the bottom of a slope, although before this it is possible
to climb up the wall and through a hole under boulders to gain a higher level,
with a view over the chamber before Bauernkrapfen Passage but no other ways
on.< / p >
2010-08-08 22:33:49 +01:00
< p > Following the rift around to the right from the end of
Bauernkrapfen Passage, passing some small
faulted phreatic tubes in the left wall,
leads to an opening in the right wall. The succeeding phreatic passage,
< b > Strudel Crawl< / b > , sucks strongly and
continues sloping down past a delicate traverse over a hole [2006-258-12-C]
to eventually arrive at a further hole in the floor [2006-258-13-B]. A
traverse line is required to cross this. Shortly after the traverse,
there is an eyehole in the right-hand wall (facing downslope), which leads
to the large passage of < b > Ribs with Knö del< / b > . Strudel Crawl may also be
followed down without going through the eyehole to reach the same point,
although this route is not recommended for descent, due to a drop underneath.

< h2 > Ribs with Knö del to Caramel Catharsis< / h2 >
< p > One exits Strudel Crawl to find the large passage of Ribs with Knö del
sloping down to the right. In this direction, a hole in the floor is
passed, before a much larger hole right across the passage is reached.
A rope belayed to bolts on the left side of the passage enables a descent to be
made to a point where it is possible to climb down, behind and around a
rock pillar to complete the crossing of the hole. A further passage leads
off from behind this pillar [QM ?].
< p > After the hole, a sloping traverse is crossed; water enters from the
roof here. This is followed by a long ramp downwards. A rope belayed to
a large thread over towards the left, well back from the lip, enables a
descent towards the right wall to reach the traverse of
< b > Caramel Catharsis< / b > . This follows the right wall, still sloping
down and passing a hole into < b > Stone Monkey< / b > ,
to a pitch of a few metres landing on a sandy floor in an
impressive chamber.
Continuing northwards past the taped floor leads
