Gouffre de Pou Meyssen
A window onto the underground Ouysse, 1 km up the dry valley from Cabouy. A 15 m collapse doline leads down to a small pool and a scree cone ending at -10 m in a big chamber of fallen strata. Downstream a large gallery at 14–20 m depth reaches Cabouy after 510 m; upstream the passage has been explored for over 850 m, growing to 8–14 m wide.
depth: 0–20 m
