These are some shots taken through the train window, travelling through the Tanggula Shan mountains at around 100 km/hr, at nearly 5,000m altitude. Our highest point was 5,076m.
The Tibetan gazelle. There were lots of them near the rail line, which is very reassuring. A few years ago they were pretty close to extinction from hunting, but the Chinese authorities have put a lot of effort into their conservation.
We also saw Tibetan foxes, wild yak, ravens, and several other birds of prey. Most of the rivers are now frozen, the ground is permafrost, but life carries on.
