Descrizione
Morfologia
The cavity has an entrance of 30 X 5 metres, with a N-S orientation, the south side being 10 metres higher than the north side. The shaft, 69 metres deep, narrows from -40 metres onwards, then immediately widens again to more than the upper part. The plan has a length of 80 metres and develops along the fracture, the floor being occupied by blocks and debris forming a ramp in a southerly direction, at the end of which we find the point of maximum depth.
Storia
Explored by the GES del CMB in 1963. The various surveys that are known give it different depths: SAS-CGB (-111); SIS-CET (-110); depending on the point of the entrance from which the measurement was taken. In the case of the ECG survey the measurement is taken from the lower lip of the entrance mouth, as established by speleological canons.
