Specificity in development of glaciation in the high mountains of Siberia - an ecological aspect
Glaciation in the High Mountains of Siberia has been notable for its specificity and characterized by the interaction of glaciers and permafrost. The combined activities of these agents determine development of such ecological phenomena as cryogenic-glacial systems (CGS). It requires an individual a...
