Soil and rock temperatures in discontinuous permafrost: Gornergrat and unterrothorn, wallis, swiss alps
Abstract The areas studied display a rich periglacial geomorphology. The effects of seasonal and perennial ground frost are visible in the form of widespread solifluction phenomena, patterned ground and numerous rock glaciers. Soil and rock temperatures have been recorded, and permafrost distributio...

Abstract The areas studied display a rich periglacial geomorphology.
