Purog Kangri Ice Field Landscape
Reference work entry
The Purog Kangri Icefield, the largest in the northern Tibetan Plateau, is composed of several ice-cap-type glaciers. It covers an area of 422 km 2 and is a rare icefield at low latitudes. Its ice reserve is approximately 52.15 km 3, and the snowline is at elevations of 5,620–5,860 m. The icefield radiates into the surrounding wide shallow valleys and forms more than 50 glacial tongues of varying lengths, which extend to the middle of the valleys or to the foothills. The largest forms a tongue with a wide tail when it reaches the foothills. Ice tower forests also form in the lower tongue section (Fig. 34).
