Bedrock topography of South-West Timan region

Abstract

Bedrock topography at the South-West Timan region reveals together with distinct buried valleys (characterized by presence of fluvial deposits at the axial parts, regular slope of fluvial bed and regular changes of alluvium thickness) significant over-depend depressions which cannot be fragments of a single drainage system, as it had been previously assumed (Bashilov, 1974). Morphology and geological features provide evidence that the overdeepenings are troughs of glacial expiration and of erosion of melt water.
