The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2016 and 2022.

A narrow descent meets a confluence of three small streams at -3m, dwindling rapidly upstream. In the line of the entrance, 10 meters away, a 6m crawl leads to a low gallery splitting in sandstones. A small low arch without a draughtt marks the terminus. The draught, felt at the entrance, comes from the second left impenetrable rivulet.
This small source drains a limestone bed in the southwest sandstone plateau (Colorado formation).
