<underground_description>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><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.</p><h4>Active system</h4><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><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><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><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.</p><h4>Fossil system</h4><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><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.</underground_description>
