An impressive, 20m wide, choked shaft which had been descended by only one Spaniard before 1986. The farmer reported that the Tortosa Group has descended to -140m but had stopped because it was too loose. Marked VT196.

In 1987 the main 70m pitch was dropped to a window onto an 8m pitch to a boulder floor and two ways on. The first, directly under the pitch was not looked at. The second hole leads to a 3m climb into a small chamber and onto a 10m pitch. The pitch is blind and the draught lost.

Jordi from the Catalans says that the entrance pitch is 100m but the shaft was re-explored in 1998 to where car-sized boulders were moving in a funnel.

In 2000, a traverse was started to a possible passage near the top of the entrance. In 2011, this was attempted again but abandoned when it became clear that some sort of bolting seat was required.
