Ordos Desert
The Wuding River(无定河) begins in the Ordos Desert in Shaanxi Province, Inner Mongolia and flows south into loess canyons and farmland. After around 100 miles it flows into the great Yellow River. The Wuding has its own tributaries, such as the Dali River, Hailiutu River, Hanjiang River, and the Danjiang River. The course of the river roughly parallels the northern route of the ancient Silk Road, now the National Highway 210.
