The influence of geomorphologic heritage on present nival erosion : Peñalara, Spain

Auteur(s) et Affiliation(s)



Description :
This paper examines how snow plays a role in current erosive processes in a high mountain area (1800-2400 m a.s.l.) known as Peñalara, located in Spain's Central Range. The hypothesis maintains that snow becomes an important erosive factor when it accumulates over sedimentary or weathered materials, therefore geomorphological heritage is a key factor in nival erosion. To test this hypothesis, the AA. identified the landforms in the study area and determined their relative ages by weathering and lichenometry, differentiating between preglacial, glacial (Recent Pleistocene) and postglacial (Holocene) forms.
