Descrizione

Morfologia

The cavity begins with a meandering gallery structured at an intersection of joints until a small watercourse is soon encountered. A narrow passage follows, low in ceiling, continuing into a spectacular gallery 8 metres high. The cave continues along the same joint ahead and gradually becomes more blocked by boulders until it becomes impassable. Morphologically the cavity presents some interesting current marks very well defined along its walls.

Idrologia

A little before entering the large gallery, on the left, a small gallery originates from which the waters come, presenting a form of forced-circulation erosion and on each opposite side creates a sumping arch that prevents progression.
