Heihe River: The broad canyon is located in Qilian County, 4,200 meters above sea level and runs over 800 kilometers. A section of 70 kilometers in the canyon is not inhabited. More than 800 glaciers are found in the canyon, covering an area of more than 300 square kilometers. The Heihe River running in the canyon is the second largest inland river in China. It flows through Qinghai and Gansu provinces and Inner Mongolia Autonomous Region, and is the mother river of the Hexi Corridor.
