Descrizione

Morfologia

The entrance was closed by a large block that had to be removed with the help of a rope and then another piece had to be chipped away. Even so, the entrance and the first 30 m vertical drop are very narrow. At 30 metres it widens and connects with another perpendicular joint, giving rise to another shaft of 16 metres, narrow at first and then opening up to become comfortable. At the bottom, an accumulation of very small debris prevents progression and completely closes the bottom of the shaft.
