Cave description:

This is a series of karstic systems, explorable only in their first sections, which connects four distinct valleys over a distance of 2 km. The main cave is at higher altitude than the others, which are active. The karstic system is a large fossil gallery, fortified with a man-made wall at the entrance and connected, through a series of areas which underwent hydrographic rejuvenation and collapsed galleries, to a narrow and elongated polje, where a river flows before disappearing into a sinkhole. Three different erosive phases, with typical vadose morphology, is recognizable

in the active cave. (R. Zorzin)
