South Central Siberia
South Central Siberia, also known as Southern Siberia, is a region of Russian Siberia west of Lake Baikal and north of the Altai Mountains. In some contexts, Southern Siberia may also include parts of Central Asian countries that neighbour Russia.
The map at right shows the Kemerovo Oblast which runs from the Altai Republic in the south to the Novokuznetsk Alatau Mountains in the north. It is a belt of mountains with steppe on both sides. Since this line makes a convenient landmark, we will look first at the Altai, then the Kuznetsk Alatau and then the west and east sides of the line. The line separates the upper basins of the Ob and Yenisei Rivers.
At approximately 49°8′8″N 87°33′46″E / 49.13556°N 87.56278°E, the borders of Russia, China, Mongolia and Kazakhstan form an "X" shape in the Altai Mountains. Mongolia and Kazakhstan are kept separate by a 40km stretch of the Sino-Russian border between the Altai Republic, a federal subject of Russia, and Altay Prefecture in the Xinjiang Uyghur Autonomous Region of China. To the east, Tavan Bogd Uul in Bayan-Ölgii Province, Mongolia, marks the end of the Sino-Russian border. To the west, is Kazakhstan's East Kazakhstan Province.
