According to Simonnot G, 2016, the site position is ETRS89 0450005 4792873.
The cave ends at a choke after a crawl. A piece of prehistoric pot has been found.
The information below 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 grid reference and altitude is likely to have been taken off a 1:25000 map. The French reference number for this site is SCD2007.
The entrance is on the wooded outcrop which borders the northeast meadows of Colorado and was explored in August 1988. The cave is a small gallery tunnel (2 X 2.5m) to a wall; it then becomes a 4 - 5m high meander, finishing at a blocked crawl.
Two other small cavities (20 and 60m to the east) also have a wall of protection for the animals. These are SCD2009 / MCP 4278 and SCD2008 / MCP4277with lengths of about 20m and 50m respectively.
