<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.

onto large boulders sloping northwest, at the southwest side of the 60m

<p>Just downslope from the foot of the Knossos pitch,
|
|
following around the wall northwards to the lowest point of the boulder
|
|
floor, is a walking sized route through a boulder choke, <b>Star Wars</b>. It
|
|
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
|
|
climb the way on is to go left down a slope SW into Tower Blocks. To the
|
|
right is <a href="offkns.htm#thamlets">Tower Hamlets</a>, which is very
|
|
obvious on the way back so the junction should be remembered.

|
|
|
|
<p>The chamber is large, domed, about 20m high in the centre and contains
|
|
some really big fallen blocks. From the normal route in, via the 4m slope
|
|
from Star Wars, keeping to the right hand wall leads round to the north to
|
|
the foot of a sand slope up NE into <a href="offkns.htm#thamlets">Tower
|

|
blocked pit to the left with a large wet window through the wall behind,
|
|
looking over towards <a href="deepwy.htm#flapjack">Flapjack</a>. A lot of
|
|
water is falling from the roof into the pit. Continuing by the right hand

wall leads to a junction with a very big phreatic passage. This junction is
|
|
<b>Carrefour</b> (French for Crossroads, and part of the long-term

<p>Turning left at Carrefour (SSW) leads past the very wet window into

<p>A large phreatic passage, with a deep (about 10m) vadose canyon, is now an

inlet to the Carrefour area, but was originally an up-dip downstream passage.
|
|
This goes northwards for 100m with an inlet on the left and a large wet pit

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

<a href="#burble">Burble</a>, in the left wall. At this corner, the

passage changes: the floor trench cuts down and widens to a high stream rift

which opens onto a big space, <a href="deepwy.htm#hgs">Hyper Gamma
|
|

|
|
|
|
<p>Any method of crossing this space now involves replacing ropes via a

long round trip, and this makes it much less viable as a way on. However,

this would probably be done if contemplating any further work beyond

|
|
|
|
<p>At the 90° corner in <a href="#cfn">Chicken Flied Nice</a>,
|
|
where the passage changes into a canyon, a small streamway passage comes in
|
|
on the left. A strong draught can be followed up here for 20m to a high aven.
|
|
A waterfall comes down on the right (along with most of the draught). There
|
|
is a traverse 2m up around the right hand wall leading to a 2m climb into
|
|
<b>Burble Crawl</b>, the most obvious way out of the aven. A tape assists the
|
|
move up into the passage for shortarses.
|
|
|
|
<p><a name="shelfi">A</a> difficult 2m climb above the Burble entrance on the
|
|
right (one bolt for security) gives access to <b>Shelf Indulgence</b>. There
|
|
is only an impassable rift (in back wall) and a small chamber here (on the
|
|
left).
|
|
|
|
<p><a name="burble"><b>Burble Passage</b></a> starts at stooping height, but
|
|
rapidly degenerates to crawling, flat out in some bits. 90m of passage leads
|
|
to Vom Pitch. A short traverse around to the right leads to 25m of walking
|
|
passage to a boulder blockage. The traverse to the left has also been made
|
|
(another bolt here for retreat), but it proved to be a dead end.

|
|
<p><a name="vomp"><b>Vom Pitch</b></a> is 37m deep, rigged with a short
|
|
traverse line, a rebelay 5m down and a deviation from a small thread below a
|
|
rock bridge (at c 20m). Below this is a further deviation tied to a small
|
|
rock embedded in the mud/rock wall which continues below this point. At one
|
|
point (above this latter deviation ?) is a sort of ledge where the pitch
|
|
intersects a hading section, forming a large convoluted chamber. This ledge
|
|
can be reached from <b>The Maze</b>. Below the final deviation, a pendule
|
|
over an undescended (though possibly blind) hole [<a name="qC1997-161-21"
|
|
href="qmtodo.htm#C1997-161-21">C1997-161-21</a> B] reaches a large boulder to which the rope
|
|
can be tied off for a tensioned abseil to this boulder floor of the chamber.
|
|
There are ways out in the eastern corner and from a ledge 8m up the northern
|
|
side.
|
|
|
|
<p>The eastern passage is the key to the Leadmine and Maze areas. It comes
|
|
almost immediately to a T-junction. Left is the <b>Maze</b> and the main way
|
|
on to <a href="#maze">Siberia</a>. (It soon unites with a crawl on the left
|
|
coming from the northern side of the chamber below Vom pitch, whilst the main
|
|
way right (north) here is bigger).
|
|
|
|
<p>Right at the first T-junction is the
|
|
<a href="farnth.htm#leadminese">Leadmine</a>, leading to Repton and the
|
|
<a href="farnth.htm">far north</a>.
|
|
|
|
<p>Leadmine would be the logical approach to <u>this</u> point from the
|

surface, if Strange Acrossfall was safely rigged. This route is described

now. For the continuation towards Siberia, see <a href="#maze">below</a>.

<h3><a name="leadmine">Repton I to Siberia via Leadmine</a> and Maze</h3>
|
|
|
|
<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
|
|
of the first chamber up a 2m climb goes northwest for a few metres to another
|
|
junction.<!-- Leadmine.14 --> Straight ahead dead-ends in 5m, whilst sharp
|
|
left (south) leads in 15m to a junction.<!-- Leadmine.12 --> Half left is 20m
|
|
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
|
|
passage - the Maze.

|
|

<h4><a name="maze">Maze</a> (1991)</h4>
|
|
|
|
<p>Left at the T-junction below Vom pitch if coming via Burble, or

|
straight ahead if coming from Leadmine, is the <b>Maze</b>.
|
|
<!-- 1991 desc. merged with William + Duncan, ref. KH 1997 p 8 -->
|
|
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
|
|
musical flake at its head, dropping into 2m wide passage. To the right, a
|
|
crawl back towards the last junction is quickly blocked by sand.
|
|
|
|
<p><a name="duckp">To the left</a>, a stooping passage through a shallow
|
|
pool, <b>Duckpond</b>, and lots of gloopy slime leads northwest into the face
|
|
of a strong draught. In about 20-30m, <a name="exhaustp"><b>Exhaustion
|
|
Pitch</b></a> is reached. This is a 22m deep hading pitch with a deviation on
|
|
the opposite wall 10m down. At the foot is a small window leading to a roped 9m climb down through flakes. The main passage here is tight and may bend
|
|
round to the same spot. The foot of the climb was the 1991 limit [<a

is another chamber and the passage continues as a traverse in rift about 5m
|
|
above the water, ending at a sharp left turn at the next pitch head. This
|
|
lands in yet another small chamber with horizontal passage going off to the
|
|
right to some further climbs down. The passage, <b>Auspuff</b>, continues in
|
|
fine form, still draughting towards the main cave at the limit of exploration
|

in 1997 [<a name="qC1997-161-26" href="qmtodo.htm#C1997-161-26">C1997-161-26</a> A]. This is at a

|
|
<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 -
|
|
the deepest point of the system at the time of exploration.
|
|
|
|
<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.

|
<p>Turning left, an easy traverse down leads to an area of some complexity,
|
|
but following the largest passage at each turning leads through it (other
|
|
routes either link up or end quickly). An awkward step across a small pit is
|
|
followed by a climb up and then a traverse along the right hand wall above an
|
|
undescended pitch [<a name="qC1998-161-01" href="qmtodo.htm#C1998-161-01">C1998-161-01</a> A].
|
|
Beyond is a slope down to a pitch, undescended in 1997 [<a name="qC1997-161-27"
|
|
href="qmdone.htm#C1997-161-27">C1997-161-27</a> A], <b>Paradox Rift</b>.
|
|
|
|
<h4><a name="paradox">Fuzzy Logic Pitches</a></h4>
|
|
|
|
<p>The head of Paradox Rift is in a slot in the floor of a large, dripping
|
|
aven [<a name="qC1998-161-02" href="qmtodo.htm#C1998-161-02">C1998-161-02</a> X], which soars out of
|
|
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.
|
|
|
|
<p>A short constriction separates the chamber below the first pitch from the
|
|
second pitch, although this poses no difficulties. A safety line through the
|
|
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
|
|
to the right while still attached to the rope from the last rebelay. There is
|
|
a rebelay about halfway down. Approaching the bottom of the pitch, swing
|
|
across the chamber to reach the head of the fourth pitch. Ignoring this swing
|
|
across, the apparent way on quickly becomes too tight.
|
|
|
|
<p>The Fourth, Fifth and Sixth Pitches follow on immediately from each other
|
|
and are short, scrappy descents against the wall, except for the Sixth and
|
|
final pitch which hangs free of the wall for about 15m.
|
|
|
|
<h4><a name="psycho">Psycho Street</a></h4>
|
|
|
|
<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.
|
|
|
|
<h4><a name="bearbum">Bearbum Passage</a></h4>
|
|
|
|
<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).
|
|
|
|
<h4><a name="casmud">Clear as Mud</a></h4>
|
|
|
|
<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.
