3996: Llana, Cueva de la
Solórzano 30T 454063 4803356 (Datum: ETRS89. Accuracy code: U) Altitude 230m
Length 71m
Area position

This site has been explored and surveyed by the Grupo Espeleológico de Santander del C.A. Tajahierro. Their survey is published in Exploraciones en Solorzano (Santander) in Los Sótanos de la Tierra, No. 5, 1980, Santander (ref. 1980a). Unfortunately the entrance position (along with many others in the publication) is very unreliable although attempts have been made to alter the given Madrid grid reference through a Greenwich grid reference to an ETRS89 grid reference, seen above. The shaft is in the La Llana area of Solórzano, next to the road.
The site, named by los lugareños, has not yet been located.
