<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
Dig</a>]. Not surveyed in 2000.</p>
