The Cliff of the Tongtian River is about 25 meters high and about 5 kilometers long, and located about 60 kilometers east of the Tanggula Mountains Town, Golmud City, Qinghai Province. The endangered wild animal bar-headed geese are used to nesting on it. Another threatened species of deer – white lipped deer, or Thorold’s deer, also lives here.
I took the aerial panorama at a height of 120 meters(calculated from the surface where the SUV is located) on 16th July, 2016. Because of the strong sunlight, I must squat in the shadow of the car, facing the iPad and manipulating the drone (the white spot in the shadow was actually a hat, it was Professor Xu and me).
Our destination was another white spot in the distance, a herdsman’s tent.
