Age determination of Lake Melkoe sediments

The formation of Lake Melkoe (64°51'30''N, 175°14'E, altitude 36 m), one of the largest lakes of the Anadyr Lowland, is related to the moraine left by the Tyellakh Glacier, which originated on the Pekul'nei Ridge. The lake (6 km long and 4.4 km wide) extends in the northwest...
