<h2>161 Kaninchenhöhle: Mainline to Siberia</h2></center>

|
|
<h3>Overview</h3>
|
|
|
|
|
|
|
|
|
|
<p>From the massive collapse at Knossos/Tower Blocks, the Northerly trending
|
|
|
|
|
main trunk of YAPATE and Chicken Flied Nice rise gradually up dip, punctuated
|
|
|
|
|
by an abrupt step up at a small fault at Staircase 36. This fossil phreatic
|
|
|
|
|
passage seems to stay consistently within the same bed of limestone as
|
|
|
|
|
far as the significant change of direction leading to Strange Downfall.
|
|
|
|
|
At this point, the cave becomes more maze-like, with passages going north
|
|
|
|
|
and northwest to Exhaustion and Siberia, and others going more east and
|
|
|
|
|
northeast through Repton towards the most remote parts of the system.
|
|
|
|
|
The complex development of the Leadmine area provides links between
|
|
|
|
|
Exhaustion and Repton.
|
|
|
|
|
|
|
|
|
|
<p>As exploration is incomplete, and the big trunk passages seem to have
|
|
|
|
|
disappeared, it is difficult to single out a "main way on" to the north.
|
|
|
|
|
However, the deep route from Siberia is now the deepest point of the cave,
|
|
|
|
|
and this is the "logical" destination of a tourist trip. The other routes are
|
|
|
|
|
described in terms of the "normal" or shortest currently known ways to the
|
|
|
|
|
remotest points of the cave, with the proviso that further exploration may
|
|
|
|
|
reveal more direct or more logical ways.
|
|
|
|
|
|
|
|
|
|
<p>"Traditionally", the easiest way to Siberia is across the tyrolean at
|
|
|
|
|
Strange Acrossfall, and through Leadmine. However, the current pushing
|
|
|
|
|
generation feel that Burble crawl is sufficiently short that it is almost
|
|
|
|
|
certainly quicker, even carrying gear and assuming that the tyrolean was
|
|
|
|
|
already rigged. Since the ropes have been removed, the tyrolean is no longer
|
|
|
|
|
considered a "main" route, except when approaching the far north.

is so named as looking up at the stupendous roof boulder is reminiscent of

|
|
the huge spaceship at the start of the film. Through this is lots of jumbled

rock and open space. Over to the left, a gap looks over the cliff west into

<a href="#tblocks">Tower Blocks</a> and to the right is a steep, loose climb

down and a small rift passage in the right hand wall. At the foot of the

right is <a href="offkns.htm#thamlets">Tower Hamlets</a>, which is very

about half way along, bypassed by a 2m down-climb on the right hand side.

25m beyond this pit (c 30m from the end), a sandy slope up on the right to a

<p>Up the slope in <a href="farnth.htm#repton1">Repton I</a>, just beyond the
|
|
|
|
|
easier climb through boulders, is a wide inclined bedding on the left hand
|

|

|
wall. This descends 10m into the <b>Leadmine</b> first explored from the
|
|
|
|
|
other end via <a href="#burblec">Burble crawl</a>. A further 25m of straight
|
|
|
|
|
passage heads northwest, until a 4m down climb on the right is reached,
|
|
|
|
|
dropping down into three sand-floored chambers.<!-- Leadmine.16 --> Left out

to <a href="farnth.htm#soilp">Soil Pitch</a>, but sharp right leads northwest
|
|

|
|
again. Turns left and right and a short step gain a long straight passage
|
|
|
|
|
heading northwest. After 25m on the left is the original way in from Burble
|
|
|
|
|
(at the foot of Vom Pitch), whilst straight ahead up a short climb is walking

This passage continues north from the junction, walking
|
|

|
|
uphill for 15m to a small chamber with a sandy ledge 2m up on the right, and
|
|
|
|
|
a crawl from the top of it connecting back to the roof of the passage just
|
|
|
|
|
traversed. The obvious way out of the chamber is left in a very high, pointy
|
|
|
|
|
rift, which is awkward to traverse along over the holes / rock bridges,
|
|
|
|
|
especially coming back. 15m of this comes to an awkward bridge down to
|
|
|
|
|
another T-junction. The crawl to the left winds back to ledge 8m up
|
|
|
|
|
<a href="#vomp">Vom pitch</a>, and thus to a climb back down into the chamber
|
|
|
|

below it. Right in larger passage (a mixture of hands & knees crawl and

hading rift) leads north to a widening and a muddy 3m climb down with a

|
<p>Four bolts, moving round to the right and to a rebelay down from the

|
|
|
<!-- ref: 1998 KH p 63, Duncan -->
|
|
|
|
|
<p>From the small chamber below the final 1997 pitch, the passage leads off
|
|
|
|
|
right, traversing over a slot in the floor for about 8m to reach a position
|
|
|
|
|
overlooking a further small chamber, this one containing a rock bridge.
|
|
|
|
|
At this point, the slot in the floor widens and can be descended to the
|
|
|
|
|
head of a further climb (tricky, best roped using a good thread belay).
|
|
|
|
|
Emerging into the chamber seen from above, the way on is a short descending
|
|
|
|
|
passage to a small pitch, rigged as a Y-hang from a bolt on each wall.
|
|
|
|
|
|
|
|
|
|
<p>Following almost immediately is the large black space of <b>Midnight in
|
|
|
|
|
Moscow</b>. Two bolts at the head of this pitch are backed up to the
|
|
|
|
|
preceding pitch rope. The lower bolt needs two maillons to avoid a rub,
|
|
|
|
|
and the first 23m of the descent are against the wall. A small knobble on
|
|
|
|
|
the right then provides a deviation, and five metres lower, a thread on
|
|
|
|
|
the left provides another. Below this, the pitch hangs free as the descent
|
|
|
|
|
continues down the centre of a significant widening of the shaft - apparently
|
|
|
|
|
where it intersects a (choked) large phreatic level. Continuing free, the
|
|
|
|
|
rope drops below this level to reach a boulder floor 55m from the takeoff.
|
|
|
|
|
|
|
|
|
|
<p>At the foot is a further pitch with a loose pitchhead, and a small hole on
|
|
|
|
|
the opposite side of the shaft, which provides a much better shelter from
|
|
|
|
|
drizzling damp and debris dislodged from the lower deviation. The pitch is
|
|
|
|
|
10m, rigged from a single spit as a continuation of the rope from above. At
|
|
|
|
|
its foot are three ways on. To the left is a climb up to an aven, which seems
|
|
|
|
|
likely to connect with the black space 10m above the foot of Midnight in
|
|
|
|
|
Moscow. To the right is a climb down, following the water through sharp,
|
|
|
|
|
brittle flakes, which becomes too tight. Opposite the rope is the main way
|
|
|
|
|
on, which leads via a crawl and past an aven, to a rift passage. This ends at
|
|
|
|
|
a short (5m) pitch. Doubling back under this is a crawl to an aven.
|
|
|
|
|
|
|
|
|
|
<p><a name="rasputin">Forwards</a>, opposite the rope, the way on leads to an
|
|
|
|
|
awkward climb down through an eyehole to a series of dried-out cascades in an
|
|
|
|
|
old streamway, <b>Rasputin</b>. The last drop needs a rope, dropping 4m from
|
|
|
|
|
naturals to a sandy mud floor. A faint draught issues from a mud choke, with
|
|
|
|
|
no way on. This point is at 1269m altitude, 527m below the 161a entrance -
|
2004-08-05 19:03:21 +01:00
|

|
|
|
|
|
|
<p>Ten metres above the foot of Midnight in Moscow, the widening blackness
|
|
|
|
|
resolves into a sloping mud and boulder floored chamber. This can be
|
|
|
|
|
entered by a swing on the rope, but all ways at this level choke. It appears
|
|
|
|
|
to be a remnant of phreatic passage c 15m wide, heading on 320-140°.
|
|
|
|
|
Only a 25m length is clear of choking sediment, presumably eroded away
|
|
|
|
|
by the stream responsible for Midnight in Moscow. To the SE of the rope,
|
|
|
|
|
reached by traversing the slope, is another parallel pitch, presumed to
|
|
|
|
|
connect to the aven seen from below.

|
|
|
|
sight overhead. The rigging is backed up to a handline which protects the

|
|
|
|
approach to the pitch down a ramp. A Y-hang gives a pitch of about 4 metres
|
|
|
|
|
to a small chamber, from which the second pitch follows almost immediately.

approach to the pitch head serves as a backup to a Y-hang, which provides a

|
|
|
|
descent against the wall for about 40 metres, passing a deviation and later

|
|
|
|
a rebelay below a large ledge.
|
|

|
|
|

<p>The third pitch is reached from the foot of the second pitch by swinging

a rebelay about halfway down. Approaching the bottom of the pitch, swing

across, the apparent way on quickly becomes too tight.

<p>The final pitch in Fuzzy Logic ends in a chamber with three ways on. Two
|

of these, opposite the rope, are climbs up of about 2.5 metres. The left-hand
|
|
|
|
|
climb is up a boulder pile, and is much harder than the right hand choice!
|
|
|
|
|
Both ways re-join immediately and lead to <b>Psycho Street</b>. To the right
|
|
|
|
|
of these climbs, following a small flow of water, the other way on leads to
|
|
|
|
|
<b>Clear as Mud</b>. To the left of the climbs is a possible low, wet way on,

|
which was not pushed [<a name="qC1998-161-03" href="qmtodo.htm#C1998-161-03">C1998-161-03</a> C].
|
|
|
|
|
|
|
|
|
|
<p>Above the climbs, Psycho Street starts as a traverse in the roof of a
|
|
|
|
|
narrow rift. After 6 metres, a right-angled turn to the right is followed by
|
|
|
|
|
a slight constriction leading into roomier passage which turns leftwards, and
|
|
|
|
|
immediately overlooks a pit some 3 to 4 metres deep, which it is possible to
|
|
|
|
|
traverse around to the left. A climb down into the pit can be made most
|
|
|
|
|
easily towards its far end. At the bottom of the pit is the way into

|
<a href="#bearbum">Bearbum Passage.</a>

<p>Psycho Street continues beyond the pit as a small passage of highly

elliptical cross-section, with the major-axis of the cross-section inclined
|
|
|

|
at some 40 degrees to the vertical. After a few metres, a rock bridge spans

|
|
|
|
the passage. The way past is a relatively easy thrutch above the bridge,
|
|
|
|
|
although the return is more difficult. A final section of crawling leads into
|
|
|
|
|
an enlargement of the passage to form a spacious rift chamber some 15 metres

|
|
|
|
long. The continuation of the crawl at the far end of the chamber is choked

with mud and rock, and is probably too small anyway. A climb up on the
|
|
|
|
|
left-hand wall of the chamber leads via a short crawl to the foot of an aven
|
|
|
|
|
about 15m high [<a name="qC1998-161-04" href="qmtodo.htm#C1998-161-04">C1998-161-04</a> B]. There is
|
|
|
|
|
an obvious passage leading off at the top of this aven, and a booming echo. A
|
|
|
|
|
cleft in the aven wall may make scaling this a relatively easy task.
|
|
|
|
|
|
|
|
|
|
<p>Just before the constriction at the start of Psycho Street, it is possible
|
|
|
|
|
to climb down back underneath the traverse in two steps each of about 1.5
|
|
|
|
|
metres, to reach a point looking down a short pitch into 'Bearbum Passage'.
|
|
|
|
|
This pitch has never been descended, since the route described above requires
|
|
|
|
|
no tackle.
|
|
|
|
|
|
|
|
|
|
<p>Halfway along the traverse round the pit just after the constriction, is a
|
|
|
|
|
small hole in the roof. Climbing up into this leads into an ascending
|
|
|
|
|
passage, which ends in a calcite blockage after about 20 metres.

|
|
|
|
|
|
|
|
|
|
<p>Having climbed down into the pit in Psycho Street, the way doubles back to
|
|
|
|
|
head under the constriction at the end of the initial rift. Here a small
|
|
|
|
|
chamber is entered, from which the way on is a narrow rift. The obvious way
|
|
|
|
|
to enter this rift is a squeeze at floor level, best tackled feet-first,
|
|
|
|
|
which leads to some moderately acrobatic passage before opening out somewhat.
|
|
|
|
|
A better option is to climb up to the top of the rift, where the going is
|
|
|
|
|
much easier, and then drop down into the wider section beyond. Soon a point
|
|
|
|
|
is reached where the route splits.
|
|
|
|
|
|
|
|
|
|
<p>Straight ahead is a short climb down into a chamber (containing an
|
|
|
|
|
attractive overhanging bed of cemented pebbles, immediately to the left of
|
|
|
|
|
the climb down). To the right is a crawl, from which windows give glimpses of
|
|
|
|
|
the chamber. After a short distance in this crawl, a double bend leads to a
|
|
|
|
|
junction, where the left fork is a narrow, steeply ascending tube
|
|
|
|
|
[<a name="qC1998-161-05" href="qmtodo.htm#C1998-161-05">C1998-161-05</a> C] containing calcited
|
|
|
|
|
pools (one of which has a dead spider trapped in it).
|
|
|
|
|
|
|
|
|
|
<p>The right fork enlarges, and splits again. Straight ahead here the passage
|
|
|
|
|
continues as an easy rift, before suddenly turning, after about 15 metres,
|
|
|
|
|
into an awkward squeeze to the right into a parallel, very tight rift
|
|
|
|
|
[<a name="qC1998-161-06" href="qmtodo.htm#C1998-161-06">C1998-161-06</a> C]. This was pushed, with
|
|
|
|
|
the enticement of a booming echo, but was abandoned after a dodgy moment with
|
|
|
|
|
a detached carbide pipe. The left hand turn at the start of the easy rift
|
|
|
|
|
leads to an exposed climb down into the chamber with the cemented pebbles.
|
|
|
|
|
From this chamber, the only way on is a climb down through boulders in the
|
|
|
|
|
floor, which doesn't go. The deepest point of this series is at -415m from
|
|
|
|
|
161a (-424m from 136).

|
|
|
|
<p>From the foot of the final pitch in Fuzzy Logic, facing away from the
|
|
|
|
|
rope, there is a pool to the right. Water from the pitch above flows out of
|
|
|
|
|
this pool to run down a walking-size passage, before disappearing down a tiny
|
|
|
|
|
hole in the floor after about 15 metres. Beyond this the passage continues
|
|
|
|
|
dry, and rises steadily. An aven is encountered, which has been climbed for
|
|
|
|
|
about 10 metres until it closes down. Various mud constrictions are passed
|
|
|
|
|
before the passage finally ends at a mud choke some 70 metres from the foot
|
|
|
|
|
of the last pitch.
