Location of permafrost in marginal regions:: Corral del Veleta, Sierra Nevada, Spain

This article discusses the methodology and techniques used in observations of permafrost, which is confined to a small enclave in south-east Spain (Corral del Veleta, Sierra Nevada, 3398 m altitude, 37 degrees 03 ' N, and 3 degrees 22 ' W). Several geophysical, geothermal and geomorphologic prospecting techniques were used to locate the permafrost at Corral del Veleta, an area highly sensitive to slight climatic variations, and to study its evolution under marginal conditions. The results from the application of this methodology confirm the location of Europe's southernmost permafrost remnant. Copyright (C) 2001 John Wiley & Sons, Ltd.
