(which is 90m higher) and also near the path.
|
|
|
|
<p>Description adapted from the references by Andy Waddington. This
|
|
translation has not been vetted by a fluent french reader, and I'm afraid it
|
|
shows rather badly in places.
|
|
|
|
<p>The entrance consists of a crack about 20cm high, which was at first
|
|
cleared as far as a chamber with no exit. The draught which had enabled the
|
|
entrance to be found now showed the way on. After having unblocked a fissure
|
|
dubbed Sas, a pitch, <b lang="fr">Escalier Anti-G,</b> was reached. This is
|
|
broken in five places. A second pitch, <b lang="fr">Puits
|
|
Andromède,</b> broken into three, leads to a short canyon, then to
|
|
several drops and pitches interspersed with short squeezes. The following
|
|
pitches can be seen as forming a single 80m shaft, the <b lang="fr">Puits
|
|
Ganimède,</b> divided into five and becoming bigger and bigger in
|
|
depth as well as width. The cave continues by a fault rift two or three
|
|
metres wide and 40m deep, <b lang="fr">Puits Trou Noir</b> (The Black Hole).
|
|
The early pitches are dry, but by this point, at -200m, the shafts are much
|
|
wetter.
|
|
|
|
<p>The explorers in 1977 started on the descent of a fine 60m pitch of
|
|
constant shape, slightly sloping, <b lang="fr">Puits Zorglub.</b> At the
|
|
bottom of this is the only chamber of the cave : the <b lang="fr">Salle
|
|
Galactique.</b> Here the cave splits into two routes, the active and the
|
|
fossil.
|
|
|
|
<h3>Active system</h3>
|
|
|
|
<p>Downstream from the chamber a drop leads to a small chamber among
|
|
boulders, the Love Nest. (No idea who ventured to call it this). Between the
|
|
boulders a 20m pitch opens, immediately followed by a 25m pitch. In fact, the
|
|
last 25m of descent drops between the walls of an immense aven to land on a
|
|
flat gravel floor. A diagonal chimney leads to a trickle of water.
|
|
|
|
<p>A fissure marks the start of the <b lang="fr">Méandre
|
|
Anti-Matière,</b> where one immediately rejoins the underground
|
|
stream. This has an average flow of two litres per second but quite rapidly
|
|
increases to 10-15 litres per second in flood. The first part of the meander
|
|
is straight and interrupted by 3 small pitches and two drops. At the top of
|
|
the first, in the roof, is the connection with the fossil system. Quickly,
|
|
the meander becomes less amenable: high and narrow, it is plastered with mud
|
|
(the anti-matter) which makes progress quite arduous. Three pitches of 5, 14
|
|
and 10m punctuate progress. This last, followed by a drop of 3m, gives access
|
|
to a section of passage blocked by clay. At the end of this, the stream
|
|
disappears into a fissure with tight impenetrable bends.
|
|
|
|
<p>The main passage continues ahead as a quite large fossil branch. After
|
|
some 50m, the draught goes into an earthy hole, the start of a big pitch of
|
|
70m in several stages, the <b lang="fr">Puits du Centaure.</b>
|
|
|
|
<p>Halfway down, the pitch is rejoined by the stream which is avoided by a
|
|
parallel fossil shaft. There immediately follows another pitch of 55m, the
|
|
<b lang="fr">Puits du Fond des Ages,</b> totally wet and characterised by an
|
|
elliptical cross-section and constant slope. At the bottom, the water is
|
|
engulfed by a fissure about three metres long, followed by a tight meander
|
|
which has not been pushed. This is the deepest point : -565m.
|
|
|
|
<h3>Fossil system</h3>
|
|
|
|
<p>Upstream from the <span lang="fr">Salle Galactique,</span> a window some
|
|
metres high gives access to a good-sized passage (3x3m on average), the
|
|
<b lang="fr">Méandre des Petits Hommes Verts</b> (the Little Green
|
|
Men's passage). One comes up against a climb of 3m at the base of which the
|
|
trickle of water is lost into a meander cut below the fossil passage (see
|
|
below). After a narrowing and a climb, the passage ends in boulders between
|
|
which it is still possible to penetrate for a dozen metres.
|
|
|
|
<p>Back in the meander below the fossil passage: this ends at the
|
|
<b lang="fr">Puit de la Comète</b> (discovered by the
|
|
<span lang="fr">Gaumais</span>), a 60m pitch, spray-lashed in its lower part
|
|
by <b lang="fr">Le Pipi</b> (the wee-wee). At the base of this pitch is the
|
|
beginning of the <b lang="fr">Méandre des Mutants.</b> This is a
|
|
passage for masochists <span lang="fr">par excellence</span> : low and tight,
|
|
gear gets caught everywhere. It ends in a series of climbs and a 30m pitch
|
|
joining the active system.
