Descrizione
Morfologia
The entrance is 4x9 metres and opens a few metres above the base of the cliff. Inside, the cave bifurcates for 14 metres before rejoining at the start of a slope. The gallery continues descending until reaching a 4 metre drop. Once this is passed, there are some joint intersections before continuing along a straight conduit that leads to a chamber. The gallery continues descending until it ends filled with sediments; before that, however, there is a 5 metre shaft that leads to a sloping gallery that leads to the lowest point of the cavity. The cave has a vertical drop of 76 metres (+3/-73) and 325 metres of passage.
Concrezioni
In the chamber there is an important lithogenic process.

Altri dettagli
At the start of a slope, Neolithic remains are found. There is also an interesting archaeological site, where some excavations have been carried out to extract material.
Storia
Cavity known since ancient times; inside, the inscriptions left by some of its explorers are preserved, some of them noteworthy in part for their good calligraphy: Bellmunt, 8 de juliol de 1765, Antón Rosso d'Ager 1765, Ezpeleta 1779.
On 4 de novembre de 1956 it is visited by E. Boixadera.
Curiously, the three known surveys of the cavity were carried out coinciding in time, between the years 1981 and 1982.
