🏔️ Tanggula Pass

The Tanggu La, Tangla Pass, or Tanggu Pass is a wide mountain pass in Southwest China over 5,000 meters (16,000 ft) in elevation, used by both the Qinghai–Tibet Highway and Qinghai–Tibet Railway to cross the Tanggula Mountains. These mountains on the Tibetan Plateau separate the Tibet Autonomous Region from the Qinghai province, and also form part of the watershed separating the Yangtze River to the north from a zone of endorheic basins with internal drainage to the south.
