Purog Kangri Glacier, the third largest glacier in the world

Purog Kangri Glacier is located in Shuanghu County, Nagqu City, Tibet Autonomous Region, within the core area of the Qiangtang National Nature Reserve. Its altitude ranges from 6000 meters to 6800 meters, covering an area of over 400 square kilometers, making it the largest glacier in the mid-low latitudes in the world. The Purog Kangri Icefield was first discovered by Chinese and American scientists in 1999 and was confirmed to be the largest glacier outside the Antarctic and Arctic. Due to global warming, the Purog Kangri Icefield is in a state of retreat. Research shows that the area of the Purog Kangri Icefield was over 420 square kilometers in 2000, but by 2021, it had shrunk to about 389 square kilometers.
