The mouth, of small dimensions, gives way to a narrow descending crawl about 3 metres long that leads us to a ledge. From here we will descend a 16 metre pit and at its base we will continue in a W direction until we cross a descending joint. At the N end we will find a short gallery that leads us to the level -24. Returning to the mouth of the 16 metre pit and making a difficult “ramonage” along the upper part of the joint, once one reaches the W end one finds a small chamber, from which one can descend a 20 metre pit that leads to the gallery that was crossed with that of the entrance pit.
