Very humid cavity with a vast chamber about 25 m long, a 2 m shaft and a low crawlway whose lowest point reaches -26.
Descrizione
Morfologia
The entrance is narrow (enlarged). It is followed by a descending crawlway on a steep slope 3 m long, then a 12 m vertical drop. One arrives on blocks at the end of a vast chamber about 25 m long by 10 to 5 wide, oriented NW-SE. The whole NW part of this chamber, raised, is occupied by an accumulation of blocks, and its SE part, sloping, by a stalagmitic floor. To the side, a squeeze gives access, beneath the accumulation of blocks in the chamber, to a small recess with a 2 m shaft whose bottom is the lowest point of the cavity (-26). At the end opposite the ladder (SE) starts a low, narrow, descending, very humid crawlway, twice bent at 90°.
Concrezioni
The SE part of the chamber, sloping, is occupied by a stalagmitic floor. The cavity contains a few concretions.
Idrologia
The cavity is very humid; the low crawlway starting from the SE end is very humid.
Progressione
At the foot of the ladder, one can descend to a landing at -17 m, then by opposition for 4 m further beneath wedged blocks. From there, blasting allowed gaining 2 m more. In the low, narrow, descending, very humid crawlway twice bent at 90° starting from the end opposite the ladder (SE), one can progress, despite blasting, only 7 to 8 m, given the instability of the scree (-19).
