One of the West Ozana Pots. A 15m, fine-looking shaft drops into a large rift. The passage to the left has a strong draught and leads to an eyehole and short climb to the head of a 15m pitch. The drop has a ledge 10m down. The base is silted up.

The hole in the wall with the draught whistling in was banged using Hilti caps and eventually the hole was enlarged enough to enter. A 19m pitch is followed by one of 12m. At the base, an easy, though dangerous, cobble dig has the draught going in.

Above the Hilti rift, a tight passage has been extended through two stal blockages to a third with a good draught.

According to Enrique Valero and members of the AEC Lobetum group, the streamway in Cueva del Coverón was extended upstream in 2012 to finish in high, wet avens close to this site. Cavers from AEC Lobetum have tried to descend Torca XLs but were unable to get past the tight section.
