Sven Anders Hedin, Trans-Himalaya: Discoveries and Adventurers in Tibet…
“ We still see the green fields down below at the bottom of the valley, the bird’s-eye view becomes more and more like a map, and the landscape behind us grows more distinct and extensive. Sharply marked orographical lines indicate the direction of the Indus valley, and the great range on its farther side rises darkly before us and covered with snow. Fifty mules from Rudok laden with salt threaten to block our way, but are driven to one side by our men. From time to time we call a halt to allow our animals to recover their wind. ”
