<h3><a id="ariston">Ariston Series</a></h3>
|
|
|
|
<p>The Ariston Series is the route to the current deepest point in the cave.
|
|
The pitch series begins with a short pitch of 5m rigged from a large thread in
|
|
the roof a few metres back, with a single spit for the vertical part, which is
|
|
almost a scramble. This lands on a large ledge formed of boulders wedged across
|
|
a narrow point, with impressive aven above. There are two choices of descent
|
|
here: one to the north, <a href="midlevel.html#veined">You're So Veined</a>
|
|
(15m) which was used in 1999, and one to the south, <b><a
|
|
href="#potulike">Pot-U-Like</a></b> (~35m) which has been the trade route since
|
|
2000.</p>
|
|
|
|
<h4>You're So Veined route</h4>
|
|
|
|
<p>One rebelay provides a good hang against the wall of You're So Veined to
|
|
reach the foot of the pitch, which is in a spacious shaft, with an impressive
|
|
aven above. From here, there are two ways on.</p>
|
|
|
|
<p><i>To the left, facing away from the pitch just descended, is a gully, which
|
|
in 1999 contained a thick layer of ice. Carefully traversing this rather
|
|
slippery section leads to the head of a small pitch of 6m, which was rigged
|
|
with a Y-hang. From here a walking size phreatic passage, <b><a
|
|
id="rainbow">Rainbow</a></b>, leads off, carrying a substantial breeze. The
|
|
passage initially descends, but then develops a narrow floor trench; as the
|
|
trench deepens, the phreatic part of the passage rises, and then ends abruptly
|
|
where the floor trench turns right and leads off as a too-tight rift while
|
|
ahead the phreas pinches out.</i></p>
|
|
|
|
<p>To the right leads into a small, very crumbly chamber, from which a short
|
|
section of awkward rift leads to a fine crow's nest in the wall of a large
|
|
rift. A very short pitch (5m) lands on a large ledge in the side of the
|
|
Pot-U-Like shaft. From here a roped traverse along the left-hand wall gains the
|
|
head of the next pitch of 12m, which avoids a large ledge which would have been
|
|
in the way but for the traverse. This pitch currently requires a rope protector
|
|
just below the Y-hang at the top. The landing is on another large ledge, where
|
|
a pool can be used to refill water containers. This is also the landing of
|
|
Pot-U-Like.</p>
|
|
|
|
<h4><a id="potulike">Pot-U-Like route</a></h4>
|
|
|
|
<p>The pitch is rigged with a traverse line which descends steeply to the nose
|
|
of a sloping rock wedged across the rift, from where an entertaining Y-hang on
|
|
the left-hand wall provides a free-hang to the base of the pitch. A ledge is
|
|
passed a few metres from the bottom.</p>
|
|
|
|
<p>At the foot of this pitch is a pool of water, or an ice pan, depending on
|
|
the conditions that year. Crossing this leads to the head of the next pitch of
|
|
14m. A backup bolt is followed by a Y-hang, which utilises one very cratered
|
|
spit only usable with a bollard type hanger. This is followed by a deviation
|
|
from the opposite wall, providing a clear hang to the bottom. The landing is
|
|
on a floor of boulders wedged across the shaft, although it seems sound. A
|
|
backup bolt protects the approach to the Y-hang at the head of the next pitch,
|
|
<b><a id="toecap">Steel Toecap</a></b> (35m). After a ledge 3m down, where a
|
|
deviation optimises the hang, the walls of the shaft bell out dramatically and
|
|
the rope hangs in stimulating isolation. About 5m from the floor a ledge is
|
|
passed, which could be gained by a swing across, where there may possibly be a
|
|
passage leading off [<a href="qm.html#C1999-204-20"
|
|
id="qC1999-204-20">C1999-204-20 B</a>].</p>
|
|
|
|
<p>At the foot of the pitch, the way on is a very chossy, sloping descent which
|
|
will require either re-rigging or bypassing (which may be possible by a climb
|
|
up and over) in future. This leads to a further short pitch (10m), which lands
|
|
in an aven chamber of ample proportions. <i>From here drops an 8m pitch,
|
|
landing on a rubble floor. The only way on is a tight rift [<a
|
|
href="qm.html#C2000-204-60" id="qC2000-204-60">C2000-204-60 C</a>], which was
|
|
penetrated for only a short distance. More progress might be possible by
|
|
someone small and imaginative. Not surveyed in 2000.</i> From the aven chamber,
|
|
a crawl leads off, followed by a descending rubble slope. The rubble slope
|
|
curves round to the right, passing a tight rift on the left [<a
|
|
href="qm.html#C1999-204-22" id="qC1999-204-22">C1999-204-22 C</a>], to reach
|
|
the bottom of a short climb up of 3m on the right, which is followed by a
|
|
scramble down on the other side. <i>From here, straight ahead is a climb up
|
|
into the foot of an aven, half-right is a short ascending passage leading to a
|
|
chamber where a traverse around the right hand wall leads to a slope down to
|
|
<b><a href="#fledermaus">Fledermausschacht</a></b>.</i> Full right is a
|
|
stooping/crawling height phreatic passage with a mud floor. This passes on the
|
|
right the other end of the crawl which led off from the foot of the previous
|
|
pitch, which provides a convenient shortcut.</p>
|
|
|
|
<p>Some 50m of alternate crawling and stooping over soft crumbly mud, including
|
|
a single point where the roof dips and the crawl is flat-out, leads to a small
|
|
chamber. Here there are two holes in the floor. One leads to <a
|
|
href="#kiwisuit"><b>Kiwi Suit</b></a>; the other drop is much shorter, and is
|
|
split into two sections by ledges on each wall part way down. The first section
|
|
of 8m reaches these small ledges, where a stream enters from the foot of a very
|
|
large aven. The next section of 11m is wet, and lands on a small ledge
|
|
overlooking Kiwi Suit just above the rebelay.</p>
|
|
|
|
<h3><a id="kiwisuit">Kiwi Suit</a></h3>
|
|
|
|
<p>The first pitch begins with a funnel-shaped opening. The initial approach is
|
|
rigged from a large pillar at the edge of the funnel (the approach to this
|
|
could be further protected by a traverse line tied round an even larger pillar
|
|
a couple of metres back). Suddenly, at the base of the funnel, there is an
|
|
impressive black space. In 2000 the descent was rigged New-Zealand style,
|
|
entirely from naturals, which seemed sound, but worrisome for us bolt-junkies,
|
|
especially given the record of 'Bomb-Proof' naturals in KH visiting the bottoms
|
|
of pitches; the current rig as of 2002 uses a pitch-head deviation, and a
|
|
Y-hang rebelay around halfway down, to keep the descent clear of walls and the
|
|
small trickle of water which falls down the shaft. This looks worryingly like
|
|
it would become a huge deluge after rain, drenching anyone on the rebelay, but
|
|
even during one epic trip in 2004 when water levels throughout the cave were
|
|
extremely high this area was no more than drippy. The floor is reached after 54
|
|
metres of descent. The way on is a short traverse, an 8 metre pitch, another
|
|
short traverse, and then a 20 metre pitch to a ledge. The final pitch from this
|
|
ledge is an impressive rift of 47 metres depth, rigged from a Y-hang backed up
|
|
to the pitch above. This is also rather drippy at the bottom if the water
|
|
levels are high, but this is not problematic.</p>
|
|
|
|
<p>The bottom here is the start of the deep and strenuous <a
|
|
href="razordance.html">Razordance</a>
|
|
series.</p>
|
|
|
|
<h3><a id="fledermaus">Fledermausschacht</a></h3>
|
|
|
|
<p>The traverse round to the pitch head is protected by a thread belay at the
|
|
start of the traverse. A substantial thread (requiring 2 slings due to its
|
|
girth) at the pitch head enables the first, sloping section of the pitch to be
|
|
descended. Soon the pitch becomes vertical, and a rebelay on the far wall (at
|
|
-5m) allows the next few metres to be descended. Unfortunately the shaft still
|
|
hades slightly, and a further two rebelays (at -15m and -28m) are required
|
|
before the magnitude of this 112m shaft starts to become apparent. A 40m
|
|
free-hanging section leads to a sloping ledge, where the shaft dog-legs again
|
|
and a scrappy descent down a gully, and a further two rebelays (at -68m and
|
|
-80m), reaches a sloping ledge overlooking the final section of the pitch. A
|
|
chossy traverse across the left hand wall appears to head into a parallel shaft
|
|
[<a href="qm.html#C2000-204-61" id="qC2000-204-61">C2000-204-61 C</a>]. A bolt
|
|
round the corner to the right allows a descent of the final 22m to the floor to
|
|
be made, where a boulder choke is met, with no way on. The whole pitch,
|
|
particularly the far wall, is rather loose and due care must be taken. A large
|
|
chockstone near the second rebelay could not be shifted, but should be treated
|
|
with suspicion.</p>
|
|
|
|
<p>Nature Note: A bat was observed flitting around in here on two
|
|
occasions.</p>
|
|
|
|
<p>At the start of the traverse to the head of Fledermausschacht is a small
|
|
crawl leading off to the right. This is initially flat-out over crumbly mud,
|
|
but enlarges after a short distance to enter a series of small mud-filled
|
|
chambers. There is no obvious way on, other than to start excavations in the
|
|
mud banks [<a href="qm.html#C2000-204-62" id="qC2000-204-62">C2000-204-62
