Fontaine Saint-Georges (Montvalent)
The main active outlet of the underground river of Padirac, rising in a 30 m pool near Montvalent above the Dordogne. From -10 m a steep pebble passage drops to -29 m into a gallery about 10 m high and 15 m wide, which reaches an air-filled aven after 350 m. Sump 2 stays at 12–15 m for 700 m, then a ramp leads to -76 m before it surfaces at 1,230 m; Guy de Lavaur first dived here in 1948.
Tiefe: 0–76 m
