Geography
editThe Yukaghir Highlands are a mountain region located at the eastern limits of the Sakha Republic and the northwestern end of Magadan Oblast, as well as a little part in the westernmost limit of Chukotka Autonomous Okrug. 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 intermontane basins of the plateau 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 1,128 metres (3,701 ft) high Mount Chubukulakh (Чубукулах).[3]
The highlands are limited by the Kolyma Lowland to the west and the courses of the Bulun and Namyndykan rivers to the south. The Kolyma Mountains rise to the east and southeast. The Arctic Circle passes through the area.[4]
Hydrography
editThe Yukaghir Highlands separate the basins of the Kolyma and Omolon rivers, both flowing roughly northwards. The latter marks the eastern limit. The Berezovka River has its sources within the area of the mountains.[5]
Flora
editThere 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.[3]
