GLACIAL GEOMORPHOLOGY OF THE LAKE TELETSKOYE BORDER

Abstract

Several morphologic types of glacial landforms in the vicinity of Teletskoye Lake were distinguished in the process of geomorphic mapping. The plan patterns of these forms, their heights, relation to other forms are described. On the basis of geomorphologic structure of region and quaternary deposits data glacial landforms were attributed to two glacial epochs. Glacial valleys, which lay out at height 900-1900 m, have been strongly changed. It was impossible to distinguish certain morphological types among them; they were conditionally attributed to Middle Pleistocene. Valleys, which are in a state of fair preservation, lay out at height 1900-2000 m and have their bottoms at height 1700-1900 m. These valleys were formed during the last - Late Pleistocene - glaciation. Two subtypes of valleys of this age were distinguished. There are no morphological evidences of glacial existence in the lake basin itself.
