通天河断崖位于青海省格尔木市唐古拉山镇长江源水生态保护站东约60公里处，断崖高约25米，长约5公里，濒危野生动物斑头雁就习惯于在断崖上筑巢繁衍。在过来的路上吐旦旦巴说如果运气好我们还会看到白唇鹿，可惜并没有看到。
The Tongtian River Cliff is a striking formation, stretching 5 kilometers long and rising 25 meters high. Located about 60 kilometers east of Tanggula Town in Golmud City, Qinghai, this area is a haven for wildlife. It serves as a nesting ground for the endangered bar-headed goose and a habitat for the threatened white-lipped deer (Thorold’s deer).
2016年7月16日，我利用飞行器对其进行了全景的拍摄。此时的飞行器高度120米（从停车处所在平面计算）当时的我正蹲在途中车后部的阴影处，面对iPad操纵航拍飞行器（阴影中的白点，实际上是帽子），我旁边的是徐老师。
I captured this aerial panorama on July 16, 2016, flying at an altitude of 120 meters relative to our SUV. The sunlight was so intense that I had to squat in the car’s shadow just to see the iPad screen while piloting the drone. If you look closely at the shadow, the white spot is actually a hat worn by Professor Xu, who was crouching there with me.
远处还有另外一个白点，那是一个牧民的帐篷，也是我们这次的目的地。
Our next destination was yet another white spot in the distance, this time a herdsman’s tent.
