The Anadyr Highlands (Russian: Анадырское нагорье|r=Anadyrskoye Nagorye)[1] are a mountainous area in the Chukotka Autonomous Okrug, Far Eastern Federal District, Russia.
The Anadyr Highlands are one of the two main mountain regions of Chukotka Autonomous Okrug. They rise southwest of the Chukotka Mountains, in the western Chukotka region. Medium height mountain ranges stretch in roughly WNW/ESE direction west of a large plateau and in a SW/NE direction in the south. The highlands rise between the Chaun Lowlands in the north, the Anadyr Lowlands in the southeast, the Kolyma Mountains in the southwest and the Kolyma Lowlands, where the Kolyma River flows, in the west.[2]
Among the rivers that have their source in the mountains, the main ones are the Anadyr River flowing off the highland limits to the southeast as the Belaya, the Bolshoy Anyuy and the Maly Anyuy —flowing westwards on both sides of the Anyuy Range. The Enmyvaam flows southwards out of Lake Elgygytgyn, later joining the Belaya, while the Chaun River flows northwards from the northwestern edge of the crater of the lake.[2]
The main feature of the highlands is the Anadyr Plateau,[3] which forms most of the eastern part.
The Anadyr Plateau is roughly 400km (200miles) long and about 150km (90miles) wide. It is located in the latitude of the Arctic Circle and limited by the Pekulney Range to the east. The average height of the plateau surface is between 700m (2,300feet) and 800m (2,600feet). Lake Elgygytgyn, an impact crater lake is located in a roughly central position.[4] The plateau is largely covered with tundra and shrubs.[3]
Besides the Anadyr Plateau, the system of the Anadyr Highlands comprises a number of subranges, including the following:[5]
