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.

An entrance of 5 x 2.5m is the top of a 21m pitch. A short climb down reaches the depth of 23m. The site was not found at the stated grid reference in summer 2002.
