The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2016.

A small, very unstable and dangerous opening by the edge of an old road and wall, with earth, blocks and roots. A penetrable cleft in the rock seems to descend to fifteen meters, a very similar level to that of the nearby river Asón. The cleft is an extension of a collapsed, clogged doline. There is no significant draught.
Noted by SC Dijon, 2008.
