Abstract
The Argualas rock glacier is located on the southern side of the Central Pyrenees (Argualas massif). Vertical electric sounding, debris surface analysis and a topographic survey were performed on this rock glacier between 1991 and 2000. High precision measurement records were obtained using a total station. Horizontal and vertical movements of the rock glacier were measured by means of sixteen steel rods. Horizontal and vertical angles and distances to each rod were measured from three stations on a bedrock ridge. Total and annual average displacements were derived from the emergence value and the horizontal displacement of each rod. Then the horizontal and vertical displacement rates in different sectors of the rock glacier were compared. The inferred surface deformation was characterized by both extensional and compressive flows as well as thinning of the frozen body. The displacement rates showed temporal variations related to atmospheric thermal changes, pointing to a high sensibility of the rock glacier.
