Trou Madame
A cave resurgence near Cénevières/Genevières on the Limogne road whose outflow feeds a stream bed that is usually dry in summer. A wide porch and sandy passage lead after 50 m to a lake where divers kit up; depending on the water level you may have to crawl 10–20 m before it is deep enough to swim. Eight sumps follow, mostly shallow (-2 to -16 m), the seventh 1,300 m long.
depth: 0–16 m
