El glaciar noroccidental del Besiberri (Pirineo de Lérida)

Abstract

The studied complex is a glacial debris system with three different areas: The upper, with an ice core covered by glacial debris and very active periglacial processes; the middle, a black glacier with a semi-covered part; and the lower, a rock glacier in the front of the complex. The end of the dynamics that generated the glacial system doesn't exceed the last few decades. This is deduced from the good preservation of the forms, the slow response of the glacial system to the climatic changes and the presence of Little Ice Age moraines surrounding the complex.
