The dive
The shaft lands directly on the start of the upstream and downstream sumps of the Bourbouillet–Reméjadou–Ranc du Bœuf system.
Profile and sections
The shaft lands directly on the start of the upstream and downstream sumps of the Bourbouillet–Reméjadou–Ranc du Bœuf system. There is lots of clay: the weathered calcite on the walls breaks off and releases black mud clouds ('avalanches') that kill the visibility.
The first descent was in 1892; diving exploration followed in 1965–1999 (incl. F. Le Guen 1978, J.-P. Baudu 1997–99).
Practical: a hiking guide calls the open shaft 'extremely dangerous' for walkers.
- Depth and profile
- Downstream: lake, fissure to -44 m, restriction at -51 m (S7, connection with Bourbouillet). Upstream: boulder slope; after 100 m a hard crawl on the left to a small sump, on the right 240 m to max -15 m with an air bell; at 465 m from the entrance -23 m, sanded low section to -42 m, explored to ~650 m. Longest sump of the system: S8''' 1,465 m. System 3,345 m long.
- Configuration
- Backmount; sidemount with small cylinders or a compact sidemount CCR also work. Large configurations (dual rebreathers, double SCR) could not pass the restrictions at the foot of the shaft in 2011.
- DPV: Not DPV-suitable (estimate)
- Restrictions and mud right after the shaft, and everything has to go down 26 m: no scooter.

How to get there
From Saint-Alban-Auriolles take the D208 towards Chandolas; after 2 km turn right onto the D246 towards Joyeuse/Lablachère. Past two bridges, up onto the plateau; at a gentle bend opposite an isolated house turn right onto a track. After ~250 m there is a collapsed dolmen with a yellow dog's head painted on the remaining stone; a forest path starts 10 m further (~5 min). The entrance is an open 3 × 7 m shaft landing on the river 26 m below: 35 m rope, 4 anchors and 1 deviation. All dive gear has to go down and back up the shaft.
