Besiberris glacigenic rock glacier (Central Pyrenees, Spain) : mapping surface horizontal and vertical movement (1993-2003)
A ten-year (1993-2003) geodetic survey was conducted at the Besiberris rock glacier, a tongue-shaped, glacigenic rock glacier, located in the eastern-central Spanish Pyrenees (42º35'48''N, 0º49'20''E). Displacement measurements were made on three traverse lines across t...
