The Muzart River starts in the Muzart Glacier (木扎尔特冰川) in the Tian Shan Mountains, not too far from the Khan Tengri Peak, and flows toward the southeast and east through Baicheng County, in the valley between the main range of the Tian Shan and the Queletage Mountains (却勒塔格山) to the south. Most of Baicheng County's population lives in the valley irrigated by this river.
