Area position : Site entrance in context : Logbook search

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. This site also has the same grid reference to site 1783 and 1784.

The 10 x 8m entrance narrows into a 40m pitch.
