Description

Morphology

Grotta profonda (deep cave), 42 m deep, consisting of a series of pits (5-25-7) that inexorably closes into a fissure. The cavity opens in the limestones of the Trias and is due to the widening caused by percolation water along two very evident fractures.

Hydrology

The air current that runs through the cavity is noticeably affected by the external atmospheric conditions.

Progression

The possibilities of continuation are very limited.

History

It was discovered by means of digging out and explored by the GSP in 1979 and revisited by the GSI in 1983.
