Khan Khentii Mountains
The Khentii Mountains rise northeast of the Tuul valley, where the forests of Siberia meet the Mongolian steppe. Mountain meadows, woodland and rocky summits surround the headwaters of several major rivers. The Tuul flows west towards the Selenge and Lake Baikal, while the Onon and Kherlen run east towards the Amur basin. The range therefore forms a divide between the Arctic and Pacific drainage systems.
