Description
Morphology
The entrance is a meandering North/South joint, which widens to become a pit about 1.5 in diameter. At the bottom, covered with scree, there is a choice between a 6 m pit, blocked at -23 and topped by a speleothem-covered chimney, and a narrow downclimb, whose entrance has been enlarged; its bottom is also choked, at -20. In the entrance pit, at -12, part of the wall has collapsed (a flat block from it remains wedged). One can regain footing on the block, and thus reach on the South side a 5 m chimney and another, neighboring, smaller one. At the same level, on the North side, a narrow lead gave, after blasting, onto a 3 m step; the floor is cut by a 9 m pit, with a narrow entrance and corroded walls; at -19, a small chimney is separated from an impassable muddy squeeze descending by a stalagmitic floor. Shortly before the bottom, on the opposite side (South direction) a fissure departs beneath a chimney-like constriction. The bottom narrows progressively, to become impassable at -25.
Speleothems
Throughout the cave, flutes and speleothems contrast with each other.
