The Olyokma-Stanovik (Russian: Олёкминский Становик; Olyokminsky Stanovik) is a system of mountain ranges in Zabaykalsky Krai, Russia. The western end of the range reaches into Amur Oblast.




Geography


The Olyokma-Stanovik is part of the South Siberian System. It consists in a number of ranges of moderate height rising in the area of the sources of the Olyokma River and stretches roughly northeastwards for over 450 kilometers (280 mi). The width of the group of ranges reaches a maximum of 250 kilometers (160 mi) in its central part. Some of the ranges are separated by intermontane basins, such as the Upper Olyokma Depression, the Tungir Depression and the Nenyugin Depression.
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.

= 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.




Flora


The slopes of the range are covered with larch taiga and pre-Alpine woodland up to 1,200 meters (3,900 ft), with dwarf birch in the bottoms of the river valleys. At elevations above 1,500 meters (4,900 ft) there is mountain tundra. Many peaks are crowned by ‘’golets’’ type bare summits.
