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 northwestern direction. The Kholmy Priozernye moraine (16 km long along the arc, 1.5 km wide, and 92-103 masl) surrounds the lake in the west and south. The lake coasts are covered by sand with pebbles and shingle. The flat lake bottom dips toward its central part to a depth of 160 cm. In distinction from many other lakes of the Anadyr Lowland, the thickness of the upper layer of water-saturated sediments overlying compact aleurites in Lake Melkoe is only 5-6 cm. Such a peculiarity of the bottom is explained by the large size of the lake, low sedimentation rates, and frequent storms caused by strong winds. Regional and local vegetation corresponds to a mosaic tundra represented by high shrubs Pinus pumila, Duschekia fruticosa , and hummocky Betula - Ericales - Eriophorum communities. Pinus pumila and Alnus form thickets on the banks of the Anadyr River, coasts of lakes, and moraine slopes.
