As the head of Urumqi River, No.1 Glacier is located in the Tianger Mountain, 120 km southwest of Urumqi, 3800-4000 m above sea level. It is 2.4 km long, averagely 500 m wide and covers an area of 1.95 km2. Around it lay out 76 modern glaciers. These glaciers are near to one another, and typical of glacier landform and sediment, and the ancient glacial warping are well preserved, so they have a reputation of “living glacier fossil” and their site is the best place in China for observing and researching modern glaciers and ancient glacial warping. Land here is characteristic of alluvial by glacier, so those conducting geological survey can explore the development course of Urumqi River in the past millions and millions of years.
