The grid reference, once estimated from the GPS position of site 900, has now been replaced with a GPS reading. (2021)

The entrance pitch of 14m is followed by an up-and-down climb of 2m in a rift to a 6m pitch, landing at the top of a slippery, 5m wide calcite slope. This ends after 30m at the head of a narrow 7m pitch, at the bottom of which is a circular chamber with a high aven. Some jaw bones are calcited to the floor at this point with the exit at the far end being another narrow squeeze onto a 4m pitch which drops into a pool. A 30m shaft follows and finally one of 15m which narrows down in calcite.

From the aven chamber a draughting, sandy-floored passage, 150m long, ends at an 8m pitch into a low, wide chamber which chokes in most directions. The draught appears to come from a small aven and various tubes in the roof.

An awkward climb enters passage which continues south and ends in a chamber after 40m with a sandy dig or a promising choke in an ascending passage. This area appears to come very close to Torca de la Vera Negra (036).
