Approach

Follow the Valle de Valdediezmo from the Sobra Valley , about 30m to the grassy bowl beneath a group of cabanas. From here climb up on to the Sierra de la Corta, and walk in a NE direction, descending the irregular ridge towards Sobra. The Torca comes into view on the left hand side, after walking along the ridge for about 15 minutes Location needs re-write…

Entrance

A shaft unmistakeable by it's size, 40m by 20m.

Description

The shaft is large and impressive, about 70m across at the top and about 25m deep. The floor is a snow plug. However, at the northern end- of the shaft is a pitch of about 10m, which has been shielded from the snow  by the wall of the Torca. This was not descended for lack of tackle, add might possibly prove a continuation.      
 
1981 journal
 A gully descent of 30m from the northern end leads down to the snow floor. No way through the snow plug was found. From a ledge on the western side of the shaft two holes lead to a parallel shaft which joins with the main one at the bottom. On the eastern side of the shaft within 10m of the edge are a number of small shafts and entrances none of which go more than 10m without choking.
