The analysis of geomorphic and biostratigraphic data on four key Late Glacial complexes located in the mountains of Chersky Range and Kolyma Upland has demonstrated that the Last Glaciation had reached its maximum in the second part of Karginsky Termochrone (MIS 3) and it had formed in the conditions of moderate humid and cool (subarctic) climate. The Glaciation had considerably reduced to the end of Karginsky Termochrone (MIS 3). During Sartan Cryochrone (MIS 2) the degradation of the Glaciation had continued and the Periglacial Area was widespread and accompanied with eolian and permafrost processes. On the boundary of Pleistocene and Holocene the small cirque-type glaciation had occurred due to the marine transgression. The Last Holocene glacial activity is related to Neoglacial Epoch and it appeared with the rock glaciers formation development.
Key words: Late Pleistocene Glaciation, Last Glaciation, chronology and paleogeography of the glacial events, Chersky Range, Kolymskoe Upland, Asian North-East.
