Have you heard of the Chang Tang?
A part of the world half the size of the continental USA?
Me neither.
George Schaller made 11 trips between 1985 and 2001. I read a couple of his books so perhaps I did hear of the region.
The photographer is Galen Rowell, who’s work was admired by Ansel Adams. This was Rowell’s last adventure. He and his wife were killed in a plane crash in California.
National Geographic sponsored expedition to Chang Tang
Bruce Kirby pitched the idea to National Geographic and worked a year on the Chang Tang project. But NG went ahead without him.
