Aven de l'Œil de Biche

At -6 m, the underground passage is made through a narrow 3-metre step, opening onto a 9-metre shaft of modest dimensions (1.5 m x 2.5 m). The last third of this shaft splits into 2 parts, cut by a rock bridge. At -18 m, the two parts emerge at the ceiling level of an imposing shaft (P20 of 6 m x 18 m). At -27 m, a fault opens on the West face of this gros puits (large shaft); it gives access to a parallel P15, whose bottom is obstructed by scree. At -39 m, a ledge to the North-West gives access to a concretion-covered gallery, whose bottom is very clayey; at the end of this gallery, an ascending shaft allows access to a crawlway that passes above this gallery. At -50 m, a 5-metre scree slope leads to the top of a final 13-metre shaft; at the bottom of this one, a 3-metre step gives onto a shaft bottom rising about 7 metres in height. The walls of the P20 are muddy.

At -39 m, a ledge to the North-West gives access to a concretion-covered gallery.

The water seems to escape at the bottom of the final shaft.

Numerous bones have been found at all levels, including a bovine femur in the gallery. The cave is marked at the orifice in May 1999[ref]Guillaume CHARDIN - CDS83, Fichier des cavités du Var > "L'Œil de Biche" (numéro 2127214) : http://www.fichiertopo.fr/display.php?details=1&indexid=1399[/ref].
