Source de Marchepied
A spring on the left bank of the Célé downstream of Marcilhac, dug open by a British Cave Diving Group team in 2002. A small cemented pool leads into a low corridor about 30 m long before the sump widens to roughly 3 × 3 m; visibility is often over 20 m. Sump 1 is 510 m long (-17 m), sump 2 only 28 m, and sump 3 drops to -69 m through a gravel squeeze at -65 m before ending in a choked shaft at -57 m, 1,338 m from the entrance.
Tiefe: 0–69 m
