<h2>The Stellerwegh&ouml;hle System, Totes Gebirge, Austria</h2>
<h4>by R.J. Barker, S. Kellet and S.R. Perry</h4>
<h3>Abstract</h3>
<font size=-1>Members of the joint C.U.C.C. and U.B.S.S. expedition to the
Totes Gebirge in Austria in 1981 extended Schnellzugh&ouml;hle (1623/115|) to
a depth of around 500m and joined Stellerwegh&ouml;hle (1623/41) to these
extensions, making 650m in all. Both caves appear to continue beyond the
limits of exploration, Schnellzugh&ouml;hle as a descending canyon streamway
and Stellerwegh&ouml;hle in a steeply descending dry phreatic passage
breaking into rifts above unentered streamways.</font>
<h3>Introduction</h3>
The Stellerwegh&ouml;hle System is the name now given to the two caves,
Stellerwegh&ouml;hle (41) and Schnellzugh&ouml;hle (115), since the
connection was made, which is the subject of this paper. 41 was the
original entrance to Stellerwegh&ouml;hle and 41a is a higher one.
<p>A description of the entrance series of both caves was given by
<a href="811309.htm">Griffiths (1981)</a> following the expedition of 1980 by
the combined Cambridge University Caving Club (C.U.C.C.) and University of
Bristol Spel&aelig;ological Society (U.B.S.S.) teams. In brief, the entrance
to 115 is a dry draughting horizontal phreatic passage which, when discovered
in 1980, ended in a choke. This was cleared to give access to a complex
abandoned system. The limit of exploration then was a ramp leading upwards
out of sight and downwards to undescended pitches at -80m. The exploration of
the lower reaches of 41 had followed a series of pitches down a high rift
passage. Here the stream was lost and then regained for a couple of pitches.
In 1980 it was last seen pouring out of sight from an undescended pitch head.
This last pitch (15m) gains a chamber now called Junction Chamber. It leads
to the connection with 115 and also to a dry phreatic series. These are
described <a href="#41andconn">below</a> in 'Stellerwegh&ouml;hle and the
Connection'.
<h3>Explorations of 1981</h3>
<h4>Schnellzugh&ouml;hle (115) (Fig. 16)</h4>
An inlet before the final ramp of 1980 was followed up eight cascades gaining
30m to a choke, thought to be near the surface and with no draught. The limit
of 1980 gave two routes on from the deepest pitch; a main shaft and a side
rift. Rubble poised at the head of the shaft directed attention to the side
rift.
<p>The route down the rift involved pitches and roped climbs of 14, 9, 7 and
27m. The pitches are broken by muddy ledges and awkward changes of angle.
They give access to a small active 'well polished' streamway, taking only a
dribble of water in fine weather. Two clean-washed pitches of 19 and 14m lead
to a damp 9m pitch onto a 15 x 15m ledge. Here the water drops left into
boulders. This section becomes very active but remains passable in light
rain, which is not the only sort of rain in Austria. The way on is over
boulders and down a 34m pitch into a 30 x 30m chamber of unseen height. The
stream drops into an uninviting slot in the floor.
<p>A 5m diameter phreatic tube can be followed downstream by traversing up
through boulders from the stream bed. This is a difficult way to follow.
Fifty metres from the chamber the tube branches into a phreatic maze of sandy
and bouldery abandoned passages. The draught was initially pursued to a
second stream and a small cairn was built.
<p>60m downstream from the 30 x 30m chamber, a large inlet on the left can be
followed up to a sloping aven. Following the stream from the chamber down the
slot in the floor, one gains a narrow meandering trench streamway. This is
some 800m long and is uncomfortable, with several awkward traverses and a
couple of drops. The last 150m is of more comfortable streamway, enlarged by
the entry of another stream, which may be the Stellerwegh&ouml;hle water from
Junction Chamber. After this a 7m roped climb drops to a sump.
<p>The sump has a 10m bypass. This is a 3m diameter tube which emerges above
a 7m pitch leading back to the stream. 50m of canyon passage, 1.5 to 2m wide
and too high to see the roof, reaches a 5m pitch and 500m of fine streamway
whcih gains depth quite rapidly by numerous sporting cascades.
<p>A 5m pitch drops to a further 500m streamway, followed by a 10m wet pitch
and 300m more passage. In two places here the vadose canyon gives way to low
wet ramps where progress is between boulders. A free 10m pitch drops into a
dark pool running into 150m of stream to the next 10m pitch, broken by a
ledge. Then after a 4m roped climb a further 70m of horizontal passage
follows which has dismal pools, suggesting the appearance of a sump. However
a 15m dry pitch gains an open streamway and a further undescended pitch of
15m.
<h4><a name="41andconn">Stellerwegh&ouml;hle</a> (41) and the Connection</h4>
Turning right out of Junction Chamber one follows a gently descending stream.
Soon the way traverses the rift above the stream to anter a phreatic zone.
Further traverses regaining and losing the stream lead to a series of
5m&nbsp;x&nbsp;5m tubes, floored in white dust with a black surface layer.
The tubes can be followed back to the Junction Chamber, which they join
10m above the floor. Ahead they take a series of swooping inclines punctuated
by dramatic bends. A final incline to a sharp left bend regains the stream
in its rift, at the site of the cairn built during the exploration from
Schnellzugh&ouml;hle. This was an encouraging sight to the explorers, who
realised that they had made the connection between the two caves (Fig. 17).
<p>From this, the lowest point of the connection, there are two routes on.
One is a traverse over the stream and then a climb over large boulders into
a passage entering from the left; the other is a 0.75m hole at floor level
to the left at the start of the final incline. The two ways join in an
uphill sandy passage, 1.5m high by 3m wide. This leads by way of a flat-out
crawl in the face of a healthy draught to a large passage. Turning right,
90m of phreatic tube lead to the main streamway in Schnellzugh&ouml;hle.
<h4>The lower reaches of Stellerwegh&ouml;hle</h4>
From Junction Chamber a 15m climb to the left gives a choice of phreatic
passages with further avens gaping above. This is a large junctional
complex into which the expected higher entrances to the system may lead.
To the right after 50m the passage leads to a rift above a stream. The
other choice is a large phreatic tube, 10 x 10m, in which easy progress
down a 30&deg; slope gains 50m depth. This scramble down boulders leads to
a cross-rift after about 150m. To the right is a stream, to the left a
traverse after a short distance. None of these routes have yet been
pursued.
<h4>The German Route</h4>
For the purpose of completing the account by <a href="811309.htm">Griffiths
(1981)</a> an extended elevation of the German Route is given in Fig. 18.
<h3>Surveys</h3>
Fig. 16 is a sketch extended elevation by Pete Lancaster. It includes the
area surveyed to BCRA Grade 5 and included in Griffiths' (1981) paper. 115
from the ramp to the bottom of the pitches and the Connection (Fig. 17) were
both surveyd to Grade 4. The vertical misclosure is 2m but the horizontal
misclosure is very large. It is thought that the compass may have been
sticking. Pete's Purgatory was measured to 800m long. Below this the section
of the streamway from the inlet to the Twelve Foot Climb (the second marked
as p5) was surveyed to Grade 3 and this has been extrapolated downstream on
the Grade 1 survey to give a total depth of 680m &plusmn; 40m.
