National Geographic : 1938 Jul
OVER THE ROOF OF OUR CONTINENT Photograph by Bradford Washburn ONLY TWICE HAVE CLIMBERS STOOD ON THE HIGHEST SUMMIT OF MOUNT MCKINLEY, NORTH AMERICA'S TALLEST PEAK "The world's mightiest precipice, . . . one stupendous cliff plunging to the plains 17,000 feet below." Thus Bradford Washburn describes the northwest face of the 20,300-foot Alaskan mountain monarch, which rises higher above the land at its base than any other peak in the world (page 97). Bradford Washburn made the first complete camera record of Mount McKinley in July, 1936, during a series of flights spon sored by the National Geographic Society and the Institute of Geographical Exploration at Harvard University.
