As noted by the Smtihsonian, this photo was taken by WW Rockhill, formerly an envoy to China who explored areas of Tibet and kept a journal of his travels. It is of the Wahon Jamkar Pass, south of Kokonor, as noted on the cardboard frame in which the photo was mounted for the Smithsonian.

I personally like the image, albeit a desolate one but one that imparts a three dimensional quality not evident in all the old landscape photos taken in Central Asia and Tibet.
