Source de Combe Nègre
A small spring at the foot of a cliff between Calès and Lanzac whose stream feeds the Dordogne. The entrance is a sub-metre tube, followed by a chain of short, shallow sumps (70 m, 50 m and 150 m at only -2 to -3 m) separated by wading sections; beyond sump 5, about 970 m of dry passage was explored in 1979.
