Brad Washburn was the greatest aerial mountain photographer of all time. Hanging out the open door of an airplane, he flew above unmapped mountain ranges - capturing iconic images with which he could make maps, pursue scientific inquiries, discover first ascents, and inspire people. More than eighty years after Washburn first photographed Denali from the air, climbing buddies Renan Ozturk and Freddie Wilkinson look at some of Washburn’s images and have this crazy idea: rather than go up, their dream is to go sideways — across the range’s most forbidding peaks, the Mooses Tooth massif.
