Clyde Spires is a 13,267-foot summit on the crest of California’s Sierra Nevada, straddling the boundary of Kings Canyon National Park and the John Muir Wilderness west of Big Pine. Formed as twin spires, with the west slightly higher, it rises sharply above Echo Lake, giving it a strikingly steep profile. The mountain was first climbed on July 22, 1933, by Norman Clyde, Jules Eichorn, and Ted Waller, who named it for Clyde, a renowned Sierra mountaineer credited with 130 first ascents. Its alpine setting is shaped by Pacific storms, and its runoff drains toward both Bishop Creek and the Middle Fork Kings River.
