Moraines of the Tyellakh Group [1] (QIII{sub 2-4}) preserved in river valleys of the northeastern Kolyma River basin indicate development of cirque-valley glaciers originating in the Kilgan Mountains located at the northeastern periphery of the Kolyma Ridge that separates drainage basins of the Sea of Okhotsk and Kolyma River. Moraines host lakes with a length of up to 1-5 km and a relatively small width depending on the valley bottom dimension. The study of lacustrine sediments, their bed-by-bed palynological analysis, and radiocarbon dating provided the first information on lake levels during the final glacial stage of the Late Pleistocene, as well as the Pleistocene-Holocene boundary and Holocene, for the upper reaches of the Kolyma River.
