This site is described on the web site of the Sociedad Espeleológica Alto Duero who have explored it. It would appear that the entrance has been located with GPS but the altitude (in brackets above) is wrong when plotted on 1:5000 maps.
A 9m long rift is a pitch of 17m. A ramp descends to a choke but at the top is the head of a 55m pitch. At the base, 2 small, 1m diameter tubes lead onto the continuation and another pitch of nearly 59m. This appears to add up to 130m and not the indicated 119m.
