Descrizione
Morfologia
The mouth has a width at its upper part of 2x1, with many loose leaves and branches. Descending a pit with almost smooth walls, one reaches a cone of humus debris, on a steep slope, which leads to a small chamber with an ascending chimney and a floor of blocks and calcified pebbles.
Concrezioni
In the small chamber, the abundant dripping has been calcifying the blocks and pebbles that fill the floor.
Idrologia
Abundant dripping is observed in the small chamber.
Progressione
From the mouth one descends an 11-metre pit and a ramp down to 15, filled with humus, which leads to the small chamber with an ascending chimney.
