Gansu is a province in north-central China. Its city of Jiayuguan is known for the striking Overhanging Great Wall and imposing Jiayuguan Pass fortress complex, both part of the Great Wall of China. The nearby city of Jiuquan is a gateway to the July 1st glacier, which crowns the Qilian Mountains to the south, and to the Gobi Desert. Jiuquan's Silk Road Museum houses artifacts from this ancient trade route.
