It consists of a single shaft with a few ledges and a large entrance (8 x 4 m). 4 metres below the lower lip there is a sloping ledge.

On the sloping ledge 4 metres below the lower lip there is usually snow and ice, but from the -15 level onwards a large amount of snow and ice appears, leaving a passage only along one of the shaft walls and filling its entire diameter from the -25 level onwards. In the summer of 1985 a passage remained open between the snow and the wall, which on that occasion allowed reaching a depth of -35 metres. In July 2023 the snow plug is less thick and it is possible to descend about 10-15 m further.

The pit was located by members of SIRE – UEC Sants during a ski traverse at the beginning of 1980, but they did not return until the summer of 1982, when they were able to descend to a depth of 25 metres, observing a small passage between the snow that went down about 5 metres further. They themselves, by then as members of SIE – CEA, returned in the summer of 1985 and were able to descend 10 metres further (level -35), where it seemed to offer no possibility of continuation. On Tuesday 25 July 2023, the cave received a new visit from Yolanda Asensio and Jordi Francés, who were able to descend a few more metres between the wall and the ice, reaching an estimated depth of about -45m or -50m, being stopped again by a very solid ice plug that seems difficult to overcome.
