Source du Marchepied
A resurgence on the Célé downstream of Marcilhac-sur-Célé, opened by British divers in 2002 after heavy digging. Three sumps lead to a choke 1,338 m from the entrance; the FFS fiche states that diving is prohibited pending access works.
The Marchepied was fully blocked until summer 2002, when a Cave Diving Group team led by Clive Stell dug open the entrance and dived the first sump. Later teams re-opened the partly collapsed entrance, shored it up and resurveyed it, and in 2008 Rick Stanton passed a gravel squeeze at 65 m in the third sump, ending at a boulder choke at 57 m.
The FFS fiche describes three sumps: S1 of 510 m (max -17 m), a short S2 of 28 m, and S3 of 668 m reaching -69 m. The air-filled passages between sumps are described as containing high carbon dioxide and low oxygen. The fiche also states that access was being reorganised and that dives were prohibited until the works were complete; no later update was found.
Ortam
A tight entrance suited to side-mounted cylinders, opening into a winding first sump; dry sections between sumps have foul air according to the FFS fiche.
Koşullar
Air-filled passages between the sumps are reported to have high CO2 and an oxygen deficit.
