The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2018 and 2022.

A small sinkhole upstream of a string of depressions dotting the valley from Rotura to Tocornal and Piluca. In the sinkhole a collapse in the yellow soil and blocks appears relatively recent (4 x 3 m and 2 m deep). A small side racking along a part of rock in place did not give a glimpse of immediately(?) [2018] A small lateral drawdown along part of rock in place did not suggest any further action. [2022]
