Kolyma Lowland

The Kolyma Lowland (Колымская низменность) is a lowland plain in the northeastern parts of Sakha Republic in the basin of the Alazeya, Bolshaya Chukoch'ya and lower reaches of the Kolyma rivers. The lowland is formed by fluvio-lacustrine loam soil about 120 m thick. The climate is subarctic.

Geography
The Kolyma Lowland stretches for 750 km along the Kolyma River from the East Siberian Sea to the Chersky Range, between the Alazeya and Yukagir plateaus. Besides the Kolyma, other rivers in the lowland include the Alazeya, its tributary Rossokha, and the Chukochya. The average elevation of the Kolyma lowland is 100 m with occasional heights, such as the 512 m high Suor Uyata.

The Kolyma Lowland is part of the wider Yana-Kolyma system of lowlands, which include the Aby to the south of the Polousny Range and the Yana-Indigirka on the northern and western sides.
