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
1782 and 1784.
This site is close to 1782 and is a large pitch, some
35m long x 12m wide which drops to a 46m pitch at the southern end.
