The dive

S2 is roomy and easy, S3 has erosion forms and passage splits. The spring is also known as Grotte de Thiourre / Résurgence du Vallon de Chame.

There is always CO₂ between S1 and S2, sometimes at high concentration. Do not breathe that air; dive here in winter or early spring, not in summer or autumn.

Profile and sections

S2 is roomy and easy, S3 has erosion forms and passage splits.

The spring is also known as Grotte de Thiourre / Résurgence du Vallon de Chame. It is a permanent spring, tapped by the commune. The terminus was reached by P. Penez and J.-C. Chouquet (Jan 1984) and resurveyed in 2004–2005 (Baudu, Vasseur, Rocheil).

Depth and profile: S1 30 m / -5 · S2 60 m / -7 · S3 35 m / -4 · S4' 340 m / -32 · S4 80 m / -17 · development 1,050 m (-32/+40), about 570 m underwater
Configuration: Sidemount or small cylinders: an awkward 2 m climb after S1 and dry sections between the sumps; S4' is a conduit of about 2 × 1.5 m. Backmount is impractical.
DPV: Not DPV-suitable (estimate): Short sumps with dry sections and climbs; S4' is narrow. No gain.
