The information has been roughly translated from the French, Spéléo-Club de Dijon reference, Degouve de Nuncques Patrick et Simonnot Guy, 1989 (in Sous le Plancher, no 4, 1989) and in Simonnot G, 2016.

This sink of a few meters (gallery 1 X 1) seems to rise 20m lower in a closed doline (SCD2020 / MCP3270). This latter site is a small resurgence yet to be explored. The water is lost again a few tens of meters further down in an impenetrable crack in a coalescent doline. Site 1757 was linked to site 3270 in 2011.

(Simonnot G, 2018 has a much shorter description)
