Post-glacial history of Accol Valley, South Chuya Range (Gorny Altai, Siberia)

Abstract

The main regularities of the recent morphogenesis in the deglaciation area of the ancient glaciation were identified. The Accol valley was particularly studied by geomorphological methods, including mapping of large scale, field observations, interpretation of aerial pictures. The predominant postglacial relief-forming processes depend on the altitudinal climatic zonality, inclination and azimuth of the slope. Erosion and slope processes followed privation and expiration during the deglaciation period. When glacier as an active transport agent disappeared, glacial valleys became the area of accumulation.
