Dinámica y morfología glaciar nn el valle de Cardaño, Palencia (cordillera cantábrica)

New data about the glacial geomorphology of Cardano valley (North of Palencia province, Spain) are presented. Using AABR (Area Altitude Balance Ratios) method we have estimated the ELA position in the last maximum advance at 1840 m. Instead of this high altitude, the great surface above this altitude permitted the development of an important glacier. Numerous erosional and depositional forms are widespread in the valley, and many of them are recognized for the first time.
