Dispatch from @coryrichards: 1940 or 2017? There is often a timeless texture to images that can mirror the quality of the landscape or resident culture. Here, there is a ruggedness to Tibet and Tibetan culture that seems unparalleled... and some pictures seem to have no solid place. These images are like orphans in time. Dorje, a Tibetan yak herder, spent two days with us, driving yaks from 17,000 ft to 21,000 ft., another vertebrae in the spine of this industry. The pay is roughly $300 USD / yak for a one way trip that takes two days. That money is split between the Chinese Tibetan Mountaineering Association and the yak drivers. Drivers like Dorje are the #unsungheroes of Himalayan climbing. But while the industry grows and evolves, some things, at least, always seem the same.... and for that, I'm forever grateful. @adrianballinger and I are currently waiting for the wind to calm for our No Os summit attempt on Everest's north side.
