The national key scenic spot, is located in the northwest qiangtang area, 90 kilometers northeast of double lake, belongs to the national class qiangtang area of the reserve. 109 national highway turned double lake area county naqu-can be up to. 560 km away from naqu town. In September 2000, the Chinese academy of sciences, cold and arid regions environmental and engineering research institute, China polar research institute, Chinese academy of sciences and the Antarctic oceanic administration for wuhan surveying the scientific research personnel and from the United States, Russia, Sweden's five scientists a line of more than 50 people, PuNuo deeply the glaciers, the comprehensive investigation. Later, a limit open to the society.

PuNuo hillock, in addition to the arctic and Antarctic glaciers are outside, the world's third largest glaciers, is known as the world's third extremely. Is the largest area of latitude glacier. PuNuo ice sheets, the area of 422 square kilometers, the ice surface smooth, in northwest toward the southeast bar distribution. Ice sheets to the surrounding valleys radiation overflow more than 50 length of tongue range ice, the lowest place altitude of 5350 meters. By drilling and radar measurement, air-10 ℃ for; In the bottom of the ice sheet, on 5 ℃ for-to-3 ℃. Ice source 6000 meters, 2000 in 2001 to in-60-the temperature reached the lowest extreme ℃.

The scenic area glacier, lakes and desert mutually co-existed, trinity. There are many lakes around the ice sheet, on the glacier melt water supplies, the largest is the source of the west to ice gorbachev cuo (also called the east lake). Lakes and ice between source, the distribution area of the desert, close to where the ice sheets and continuous crescent open dunes, only in the desert area east of ice reached 500 square kilometers above. The desert with latitude area is the first that has found glaciers frontier sandstorm landscape, this landscape and strata records at least some ten thousand years of climate, glacier, desertification have contributed to the role. Source area under the ice ice in the abrasion movement is given priority to, the special role of glaciers is creating plenty of silty sand and fine particulate matter, for the development of the desert provides a rich source of things. Made the region desert as the world development with the highest level of the desert, so can be called the glacier type desert.

If the glacier, at nature reserve in qiangtang core areas along the way, and its surrounding areas can view and admire the swarms of and Tibetan antelope, wild wild yak hidden and wild animals. November to April next year before and after, can view and admire plateau lakes make godot winter ice wall, concerning the pups wonderland, etc.
