Qíliánshān

The Qilian Mountains rise along the northeastern edge of the Tibetan Plateau, south of the Hexi Corridor. Snowy summits and glaciers feed streams that run towards the oases and eventually disappear in the desert. The Heihe, or Ejin, is among the rivers born in these mountains. Conifer forests cover parts of the slopes, and passes connect the plateau with the corridor to the north.
