Gemma Yangzong Glacier means "a pile of sand and stones arranged in a cross shape" in Tibetan. It is the source of the Yarlung Zangbo River and is located at the junction of Zhongba County in Shigatse Prefecture and Pulan County in Ngari Prefecture. The altitude here is 5,590 meters, the terrain is flat, surrounded by steep mountains, and glaciers span the valleys.
116 square kilometers of the area are covered by glaciers and permanent snow. The glaciers flow out of two mountain peaks, about 4-5 kilometers long and 1 kilometer wide. The crystal glaciers have different postures and slowly melt, dividing into hundreds of small rivers, forming a network layout. About 10 kilometers below the glacier, a big river merges into a big river, which then melts into the "Kubiqu", that is, the Maquan River. This is the upper reaches of Yarlung Zangbo.
