Tsökh

Tsökh is the Mongolian name for the Chikoy, a river that rises in the wooded highlands east of Lake Baikal. Its course follows the northwestern edge of the Khentii-Daur uplands before joining the Selenga as a right-bank tributary. The river usually freezes in late autumn and remains beneath the ice until spring. Its largest tributary is the Menza, which drains mountains to the south.
