Cartografía del permafrost de montaña en los Pirineos españoles
Abstract
Mountain permafrost map of the Spanish Pyrenees. Since the 1980’s with the development of research on rock glaciers and periglacial landforms as permafrost indicators that the mountain permafrost is known to occur in the Pyrenees. In this paper we present a map of the distribution of mountain permafrost in the Pyrenees. The mapping is based on indicators of permafrost (rock glaciers, gelifluctionprocesses, ice caves, patterned ground, vertical electric sounding and ground thermal regimes) and geographical information extracted from a Digital Elevation Model, such as slope angle and aspect, altitude and potential direct solar radiation. The map represents the spatial distribution of “probable” and “possible permafrost”and represents the present-day state of the art on Pyrenean permafrost.
