According to Simonnot G, 2016, the site position is ETRS89 0451603 4792801

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), repeated in Simonnot G, 2016. The French reference number for this site is SCD2010.

On the northern side of a large doline near to the Tocornal path.
A pitch of 28m (2 X 2m)  with a ledge at -5m. At the base, a lightly draughting meander becomes impenetrable. At -15, a narrow window appears to give access to a parallel pitch (to be re-examined).
