The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2016.
A steep doline with a base full of uprooted trees and collapse along the bedrock. (Collapsed in February 2009?) A brick trough remains suspended in the northern flank after the path that allowed cattle access slid away. In February 2010 the base appeared lightly capped. The sinkhole itself goes to a canyon (with small shaft to the side) located above. The area covers about fifty meters and 30 m elevation.
Documented by the SC Dijon, February 2009.
