Glacial lakes of the Magadan region - Grazevoe (61°08’21” N, 152°19’57” E), Tschuchye (61° 08.780’ N, 152° 19.860’ E), Nalimnoe (61°07’41” N, 152°20’8” E), Chernoe (61° 06.690’ N., 152° 15.570’ E), Sosednee (62°03’29” N, 149°31’22” E), Sapog (63°29’9” N, 147°50’41” E), Vodorazdel’noe (63°44’8” N, 148°13’4” E), Ui (63°49’31” N, 147°53’21” E), Forel (63°50’01.61” N, 147°51’03.75” E) have been studied. Most lakes were formed at the end of the Late Pleistocene or at the beginning of the Early Holocene. The sedimentation features of the Late Pleistocene and Holocene differed significantly. The Late Pleistocene stage is characterized by the dominance of terrigenous sediment, while the Holocene is dominated by biogenic sedimentation. The key biotic and abiotic paleoenvironmental proxies from glacier records are shown.
