Tannu-Ola

 

a mountain range in the southern Tuva ASSR. The Tannu-Ola Range forms the divide between the river basins of the upper Enisei and the Ubsu-Nur, a lake with no outlet to the sea. It consists of the Western Tannu-Ola and the Eastern Tannu-Ola; the total length is about 300 km. The range rises from a middle-height relief to an average elevation of 2,500 to 2,700 m; the highest elevation is 3,061 m. The Western Tannu-Ola is composed of sandstones, schists, and conglomerates, and the Eastern Tannu-Ola, of extrusive and sedimentary rocks and granites. Taiga consisting chiefly of cedars and larches covers the northern slopes up to elevations of 2,000 to 2,200 m. Steppe vegetation grows on the southern slopes. There are rock streams and high-altitude tundra on the gently undulated peak plain.
