Grotte de Combe Nègre

From the entrance, an agglomeration of roots and sand blocks the way. Three times the gallery is cleared and progress continues through a very low crawlway filled with roots, pebbles and sandbanks. After 60 m, the crawlway opens onto water, which stagnates for 20 m and forces the caver to get almost entirely wet, so low is the ceiling. After 80 m of dry gallery, the water reappears. The crawlway continues, but the passage between the ceiling and the water, too narrow, stops progress.

The water encountered after 60 m stagnates for 20 m; very cold, it is doubtless the residue of heavy rains accumulated at the lowest point of the cave. After 80 m of dry gallery, the water reappears: a thin trickle can be heard flowing which, it is supposed, seeps into a sand-filled gallery. The cave would function as an overflow.
