The Olyokma-Stanovik (Russian: Олёкминский Становик; Olyokminsky Stanovik) is a system of mountain ranges in Zabaykalsky Krai, Russia.[1] The western end of the range reaches into Amur Oblast.[2][3]
Geography
The Olyokma-Stanovik is part of the
intermontane basins, such as the Upper Olyokma Depression, the Tungir Depression and the Nenyugin Depression.[2]
The average summits of the Olyokma-Stanovik reach between 1,200 meters (3,900 ft) and 1,600 meters (5,200 ft). The highest point is a 1,908 meters (6,260 ft) high Golets Kropotkin. The range rises in an area prone to earthquakes.[1]

Hydrography
The Olyokma-Stanovik forms the main watershed between the rivers of the
Lena basin (flowing into the Arctic Ocean) and the ones of the Amur basin (flowing into the Pacific Ocean). The Olyokma, a right tributary of the Lena, and its tributaries Srednyaya Mokla, Tungir and Nyukzha have their sources in the highlands. Other important rivers originating in the highlands are the Nercha, Kuenga and Cherna, left tributaries of the Shilka, as well as the left tributaries of the Amur: Amazar, Urka and Urusha, among others.[2]
Flora
The slopes of the range are covered with
mountain tundra. Many peaks are crowned by ‘’golets’’ type bare summits.[3]
