Small cavity with a 17-metre vertical shaft with a ledge, a 10-metre aereal shaft and a large descending chamber in a boulder chaos, with beautiful flowstone.
Descrizione
Morfologia
Vertical shaft of 17 metres that gives access to a descending ledge with loose blocks of 3 metres, ending in an aereal shaft of 10 metres. At the end of this, a chamber of enormous dimensions opens up, descending in a boulder chaos. Almost at the end of the chamber, on the left-hand side, there is a narrow passage. It is a small cavity.
Concrezioni
It presents very beautiful flowstone.
Progressione
To reach the 4-metre descending meander, ending in a small shaft and narrow section of 3 metres, one passes through the narrow passage located almost at the end of the chamber, on the left-hand side. This small shaft and narrow section gives access to the 7-metre meander, which becomes impassable for cavers and constitutes the end of the pit.
