Mount Witherspoon is a elevation glaciated summit located northwest of Valdez in the Chugach Mountains of the U.S. state of Alaska. It's set on land managed by Chugach National Forest. This remote mountain, fifth-highest in the Chugach range, is situated northwest of Mount Einstein, with the heads of Yale Glacier and Columbia Glacier between the summits. It is the second-highest peak in the Dora Keen Range, which is the 25-miles-long divide separating Harvard Glacier from Yale Glacier. The mountain's name was officially adopted in 1928 by the U.S. Board on Geographic Names to honor David C. Witherspoon, a U.S. Geological Survey topographer for 30 years, who at the time of his retirement in 1921 had mapped a greater area of Alaska than any other man. The first ascent of Mount Witherspoon was made June 25, 1957, by David Bohn, Arthur Maki, Jr., Martin Mushkin, and Lawrence E. Nielsen.
