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 1.5 x 1.8m opens out onto a choked 19m pitch. This could be the p50ft mentioned in anon., 1977b - the 1977 logbook (3/8/77).
