The dive
A Vauclusian shaft on the underground course of the Claysse, with water of about 12.5–13 °C. The shaft lies downstream of the Sauvas–Peyrejal–Cocalière system and upstream of the résurgence du Moulin.
Profile and sections
A Vauclusian shaft on the underground course of the Claysse, with water of about 12.5–13 °C.
The shaft lies downstream of the Sauvas–Peyrejal–Cocalière system and upstream of the résurgence du Moulin. The first dives were in 1955; on 24 Jul 1955 a fatal accident happened here, the third cave-diving death in France. Trimix expeditions followed in 1999–2001 and rebreathers from 2005, including Volanthen and Stanton in 2006.
- Depth and profile
- Siphon Nord to -78 m, 1,020 m long (CDS07 2021): entry down a gravel/silt slope to -7 m, then a low bedding plane into a fracture; sections 2 × 1.5 to 4 × 3 m · Bertrand Léger branch (SW): S1–S8, 18–118 m long, mostly -2 to -6 m, S8 -18 m; ends in a boulder choke at 1,004 m · total 2,141 m (CDS07); fiche: -87 m vertical range
- Configuration
- Sidemount: low bedding planes in the Siphon Nord, and S1 of the Léger branch requires taking your kit off. For the deep Siphon Nord, CCR with trimix (explored with rebreathers since 2005).
- DPV: Not DPV-suitable (estimate)
- Clayey low bedding planes and short sumps in the Léger branch; not a scooter dive.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
From Saint-André-de-Cruzières go to the hamlet of Chadouillet, turn left at the (former) phone booth between the houses; signs 'Event de Peyrejal'/'Côtepatière'. Leave the car at the bridge and walk the dry bed of the Claysse; a slope of rounded pebbles leads down to a small, clear spring pool.
