Geography

The Yukaghir Highlands are a mountain region located at the eastern limits of the Sakha Republic and the northwestern end of Magadan Oblast. They include two medium height mountain ranges, the Chubukulakh Range and the Siversky Range, as well as a plateau, the Yukaghir Tableland.[2]

The average height of the plateau surface is between 300 meters (980 ft) and 700 meters (2,300 ft). In the ranges a few scattered mountains rise above 1,000 meters (3,300 ft) and the highest point is 1,117 metres (3,665 ft) high Chubukulakh (Чубукулах).

The highlands are limited by the Kolyma Lowland to the west, with the Kolyma Mountains to the east and southeast.[3] There are sparse forests of larch in the lower slopes of the mountain ranges and thickets of dwarf stone pine at higher altitudes. The mountaintops are covered with tundra.[4] The Arctic Circle passes through the area.

Hydrography

The Yukaghir Highlands separate the basins of the Kolyma and Omolon rivers, both flowing roughly northwards. The Berezovka River and the Korkodon have their sources within the area of the mountains.[5]
