Igue de Cloup Seguier

From the entrance, an ovoid shaft that widens as it goes down. There are side passages, hopeless in our opinion.

At -32 M, we reach a ledge. The bottom chamber, pear-shaped, about 17 M x 10 M, has a steeply sloping scree slope; several small side passages and diverticula are found at the top and bottom of this scree. From the top of the scree, looking straight ahead, three "windows" can be seen: one is the direct descent shaft in the middle, another on the right the descent via the adjacent shaft, and on the left the last one, which was the object of the second climb. Having reached this "window", on looking up one notices a vast chimney starting from the ceiling of the large chamber, whose height our lamps could not probe.

The P30, ovoid then circular, of small diameter (4 metres on average) opens halfway down onto a chamber. From this chamber (13 M x 10 M), we explored and dug out to descend on either side into crawlways, narrow passages, a chamber, a 6-metre shaft and a terminal passage at -83 M on one side, on the other a terminal chamber, bumpy with an old water inflow, calcified but with a draught.

The 12-metre climb, at the top of the chamber, revealed a fairly wide continuation, clayey, concretion-covered, tortuous, with bell-shaped ceiling, marking the certain passage of water under pressure. This development continues, overhanging the contour of the chamber, to head towards another horizontal side passage, but very narrow and not at the same level.

Resuming the progression, after a roughly concretion-covered upward slope, a 30-metre shaft is discovered.

In the P30 chamber, as in the diverticula, there is clear evidence of water sometimes passing with force.

At -32 M, two possibilities for descent: a. continuation by a direct slope and steep drop joining the bottom chamber at -62 M; b. in parallel, a series of small shafts ending safely in the same chamber. Still on the -32 ledge, a climb to the ceiling was not successful.

At the level of the start of the 30-metre shaft, on the side, another chimney bending quickly seems interesting; at present, we have not attempted to climb it.
