Underground network with three entrances comprising a 40-metre shaft, two vast chambers and a bottom at -80, with a temporary stream that dries up in summer.
Descrizione
Morfologia
The cavity has a 1 m x 0.8 m opening and two other entrances, the 3rd having been discovered in 1972 by ALPINA. It presents a 40-metre shaft and 2 vast chambers, with a NW orientation and a bottom at -80. P = -67 ; L = 210.
Concrezioni
The descending gallery of the classic network is cluttered with scree and speleothems.
Idrologia
The stream is temporary and dries up in summer.
Progressione
The classic network begins with a 40-metre shaft in stages, continuing to the northwest by a descending gallery cluttered with scree and speleothems down to the -58 m level. To the south, on the right going down, an equipped 5-metre shaft gives access to a large chamber parallel to the previous gallery, the lowest point of the pit at -80 m. Towards the top of this gallery, shortly after the 5-metre shaft, on the right going down, a narrow joint leads to an immense passage of imposing cross-section and 75 metres long. A large ascending scree slope followed by a chimney extends this large gallery.
