Tanggula Mountains

The Tanggula (Chinese: , pTánggǔlāshān, or 唐古拉山脉, pTánggǔlāshānmài), Tangla, Tanglha, or Dangla Mountains (Tibetan: གདང་ལ་།, wGdang La, zDang La) is a mountain range in the central part of the Qinghai-Tibet Plateau in Tibet. Administratively, the range is in the Nagqu Prefecture of the Tibet Autonomous Region, with the central section extending into the Tanggula Town and the eastern section entering the Yushu Tibetan Autonomous Prefecture of Qinghaiprovince.

Tanggula is the source of the Ulan Moron and Dam Qu Rivers, the geographic headwaters of the Yangtze River. It functions as a dividing range between the basin of the Yangtze in the north and the endorheic basin of northeastern Tibet in the south.
