|
<h3>Entrance series</h3>
|
|
|
|
<p>The entrance is in a small shakehole situated on the ridge separating
|
|
<span lang="de">Feuertal</span> and <span lang="de">Hintergras.</span> The
|
|
cave starts with four pitches (p14, p11, p5 and p11) which drop onto a slope
|
|
formed of big boulders (rope desirable). After this, another series of small
|
|
pitches (p9, p7, p6, p4, p10, p18, p11) from which is reached the
|
|
<span lang="de">Sinterterrasse</span> at -141m.
|
|
|
|
<p>From this point, one has left the zone of small pitches and started a
|
|
series of pitches which in reality are part of a single shaft down to -400m.
|
|
|
|
<p>Indeed, if you had an unfortunate accident on the
|
|
<span lang="de">Sinterterrasse,</span> you would fall all the way to -400m.
|
|
These pitches are usually wet, especially after rain... Here is the list of
|
|
pitches: p25, <span lang="de">Schuppenstufe</span> 30, p10,
|
|
<span lang="de">Sicherungsstufe</span> 32,
|
|
<span lang="de">Schachtgabel</span> 48, a 10m ramp, <span lang="de">Josef
|
|
Schacht</span> 100m. On the <span lang="de">Josef Schacht,</span> a pendulum
|
|
6m from the top enables one to reach the entry to the Horizontal network.
|
|
Descending the <span lang="de">Josef Schacht</span> a little further, after a
|
|
6.5m and a 10m pitch, access can be gained to a wide canyon, active in the
|
|
bottom, and which ends in a fissure. This canyon is fossil in the upper level
|
|
and certainly presents possibilities for continuation.
|
|
|
|
<h3>Lateral development from <span lang="de">Josef Schacht</span></h3>
|
|
|
|
<p>After one has crossed the "doorway" and a short squeeze, one
|
|
enters the network proper. At this point is a passage covered in rather
|
|
special formations. The first junction gives access to a network ...
|
|
[unfortunately there are lines missing in my photocopy of
|
|
<span lang="fr">Spéalp</span> 1]
|
|
|
|
<h3>The Vegetable Garden</h3>
|
|
|
|
<p>This fossil system, which has not been fully travelled through, contains
|
|
numerous possibilities. It is reached by three principal access routes: the
|
|
pitch already mentioned; a descending fissure a little before the Belgica;
|
|
and a sloping passage with formations in the Mammoth pitch chamber. The
|
|
system is composed of a big chamber with numerous passages and junctions; it
|
|
is very poorly known and no doubt houses many surprises. Continuing along
|
|
the passage, one passes a step of 4m to find a junction, to the left at
|
|
which lies the bivouac.
|
|
|
|
<h3>Belgica system</h3>
|
|
|
|
<p>Directly after the bivouac, there is a 10m pitch, and at the bottom, a new
|
|
junction: downhill the Belgica passage, of fairly small dimensions, which
|
|
leads, after traversing past three holes, to a descent of an 8m and a 17m
|
|
pitch and to the squeezes passed by our French colleagues.
|
|
|
|
<p>Uphill, discovered by D.Motte and PIE, in the course of the expedition in
|
|
1974, is the <span lang="fr">Galerie de Francs Comtois.</span> This is a
|
|
large ascending fossil passage interspersed with traverses, dips and pitches.
|
|
It reascends to -90m. At -150m, a 20m pitch reaches the <span
|
|
lang="fr">Résomega.</span>
|
|
|
|
<p>A little before the 20m pitch, a short descending canyon passage avoids
|
|
the 20m pitch and the series of squeezes following it. The <span
|
|
lang="fr">Résomega</span> is an alternately ascending and descending
|
|
passage, very chaotic, interspersed with several junctions and pitches which
|
|
leads to the <span lang="fr">Balcon du Visionnaire,</span> offering several
|
|
possibilities. A 60m pitch gives onto another 60m pitch which is undescended.
|
|
There is another big pitch in excess of 100m and an unfinished ascending
|
|
passage. A little before, a 10m pitch allows one to reach a passage
|
|
interspersed with 3 junctions and 7 exits ! This shows the level of
|
|
complexity which we ran into.
|
|
|
|
<p>It was also at the <span lang="fr">Balcon du Visionnaire</span> that an
|
|
accident occurred in 1975, which terminated exploration in that year.
|
|
|
|
<p>Back in the Horizontal network, and after passing a little bouldery climb
|
|
an inlet is encountered, named The Bath. The passage continues a little
|
|
longer, to end in a pitch. [ exploration incomplete ]
|
|
|
|
<p>The following junction has been named Mammoth Junction because the
|
|
passage to the right leads onto the pitch of the same name. It is necessary
|
|
to exercise great care and attention not to slip hereabouts, because a fall
|
|
would drop you into same.
|
|
|
|
<p>The Mammoth Pitch, Para-pitch and probably the Negus pitch, form part of
|
|
the same system (see survey) which is composed of a 146m pitch, a 10m
|
|
pitch and a narrow canyon interspersed with several cascades leading finally
|
|
to a 35m pitch giving onto the sump at -612m. The Para-pitch, p106, is
|
|
followed by pitches of 5, 10 and 50m and drops via the latter into the
|
|
Mammoth Canyon.
|
|
|
|
<p>The Negus pitch, which is undescended, should also drop into the same
|
|
canyon. Several other small pitches and active streamways should also rejoin
|
|
this system.
|
|
|
|
<p>The depth of 612m should be treated cautiously because the method of
|
|
survey used (based on the height of a man) is fairly imprecise. The bottom
|
|
could be anywhere between -580m and -630m. The shortage of time prevented us
|
|
from redoing our survey. [The depth quoted in <span lang="fr">Atlas des
|
|
Grandes Gouffres</span> is -607m, which is shown as the bottom of this
|
|
system. However, a Belgian survey shows the Yodl system (which is supposed to
|
|
end at -607m) to be somewhere else entirely, so it is rather unclear which
|
|
survey is wrong.]
|
|
|
|
<p>Turning left, the Zipfer passage is followed for 150m before reaching an
|
|
important junction: to the left Chimneys passage, to the right Draughting
|
|
passage.
|
|
|
|
<h3>Chimneys Passage</h3>
|
|
|
|
<p>This is very large with a constant slope, interrupted in the middle by a
|
|
squeeze and a couple of drops. The <span lang="de">Schnaps</span> pitch (40m
|
|
with an unexplored, narrow canyon) is avoided by traversing to reach a 25m
|
|
pitch in which you must pendulum 5m from the bottom in order to reach a
|
|
chamber in which is met a small stream. Climbing up a little opposite, a
|
|
short upper passage rejoins the stream by a 20m pitch. In the chamber, the
|
|
descent of a 10m pitch allows the stream to be followed to a squeeze beyond
|
|
which one can hear the grumble of a large river ? A place to go back to.
|
|
|
|
<h3>Draughting passage</h3>
|
|
|
|
<p>This is fossil, and tight in places, and allows exploration of a very
|
|
complex network which intersects itself in various places and which could
|
|
hold very great surprises, since its exploration has only been sketchily
|
|
outlined. The exit from this passage is in an area of boulders where two
|
|
possibilities exist:
|
|
|
|
<p><b>To the left</b>: a tight passage has been forced on a slope to
|
|
<span lang="de">Kitschacht</span> (Tackle Bag Shaft) a magnificent 50m drop,
|
|
very wide and completely free hanging. At its base, several possibilities. A
|
|
tight active canyon which can be bypassed by a fossil passage, broken by an
|
|
earthy drop of 3m to a huge 15m pitch leading to a sump at -360m.
|
|
|
|
<p>A drop of a few metres gives access to a huge fossil passage (10
|
|
× 5m). The floor of this is cut by a deep canyon which has not
|
|
been explored. After a hundred metres or so the passage ends at a vast wet
|
|
pitch. Climbing over a big boulder on the right gives access to another pitch
|
|
upwards.
|
|
|
|
<p>Just after the base of <span lang="de">Kitschacht,</span> a passage of 80m
|
|
makes a connection with the system of the
|
|
<span lang="fr">Décollement</span> pitch at the bottom of the 40m
|
|
shaft. A canyon leaving the junction passage can be followed for more than
|
|
300m, and exits, in several places, into the side of the big fossil passage,
|
|
just before the pitch upwards.
|
|
|
|
<p><b>To the right</b>: The <span lang="fr">Décollement</span> pitch,
|
|
with, at its base, a sloping chamber full of boulders. To the left a very
|
|
deep ascending canyon is unexplored. In the bottom is the
|
|
<span lang="fr">Méandre Emeri,</span> so called because the formations
|
|
are orientated in the direction of progress and of the draught. This rejoins
|
|
a wide pitch with an inlet. After this 15m pitch is a short canyon and a damp
|
|
40m pitch. At the bottom, a huge descending passage suddenly turns almost
|
|
vertical. This is the Toboggan, needing 20m of rope (a very spectacular
|
|
passage). At this level one again cuts a new streamway. The passage
|
|
continues, then contracts, and chokes at -385m.
|
|
|
|
<h3>Extensions to the Belgica system (various Belgians, June/July 1977)</h3>
|
|
|
|
<p><b>After the Bivouac</b>: a 10m pitch, then turn left into a small
|
|
passage, ignore three pitches to the side, then descend pitches of 8 and 13m
|
|
to arrive at some easy squeezes on the left. After this, a climb of 5m and a
|
|
42m pitch. Stops in a sand blockage at -410m.
|
|
|
|
<p>Over the 13m pitch a small passage goes to several climbs in a fossil
|
|
series. There is a 25m pitch and two 10m pitches ending in several very
|
|
tight chimneys.
|
|
|
|
<h3>Yodl system (explored GSAB, August 1977)</h3>
|
|
|
|
<p>From the entrance, after 70m down <span lang="de">Josef schacht,</span>
|
|
climb down 7m over a large block and descend about 12m in the bottom of a
|
|
meander. Progress is then in the meander, with a short climb in a fault on
|
|
the left and a 120m pitch, in sections of 22m and 100m. Beyond is a tight
|
|
canyon with a 20m pitch to a sump at -607m (the last part of the 100m pitch
|
|
is wet).
|
|
|
|
<p><span lang="fr">Atlas des Grands Gouffres du Monde</span> 1979 says that
|
|
the original -395m route goes on to c-470m (unsurveyed) and there are also
|
|
routes ending at -385m and -386m.
|
|
|
|
<b>Exploration</b>: Discovered by Upper Austrians in 1856.<br>
|
|
|
|
The point -320m was reached by them in 1958.<br>
|
|
|
|
In 1967 and 1968 the <a href="../../others/bec/index.htm">Bristol Exploration
|
|
Club</a> reached -395m, the Horizontal network, with a length of 1 km, was
|
|
discovered.<br>
|
|
|
|
In 1972, 73, 74 and 75, the GSAB <span lang="fr">"Les Gours"</span> explored
|
|
and discovered over 5km of passage and about 1500m of pitches. This got them
|
|
to -612m. We note also the participation, in 1974, of three clubs from
|
|
Eastern France: <span lang="fr">S.C.Vesoul, G.S.Clerval &
|
|
S.S.Daules.</span> In 1975 CARSS joined a mini-expedition in July and
|
|
likewise, CASEO in August.<br>
|
|
|
|
A GSAB expedition in August 1977 connected a new entrance
|
|
<span lang="de">(Frigoschacht)</span> at -130m, surveyed the Vegetable Garden
|
|
and explored the new areas Yodl and KGB.
