Here are pictures taken by Joseph Rock in 1926 and my own follow-up taken in 2012, of the Ragya (Lajia) monastery in Qinghai, on the banks of the Yellow river. As you can see - not much has changed.
Kham then and now. A photoblog showing how eastern Tibet looked in the 1920s and how the same places and people look now. Based on the explorations of botanist Joseph Rock.
