Longs Peak, rising 14,256 feet in Rocky Mountain National Park, is the northernmost fourteener in the Rockies, the park’s highest point, and a dominant landmark above the Great Plains. Named for Major Stephen Harriman Long after his 1820 sighting of the Front Range, it also preserves older names linking it with nearby Mount Meeker. Probable Indigenous ascents preceded the first recorded climb in 1868, and the mountain later gained fame through writers, climbers, and rescuers. Known for its broad summit, the Diamond’s sheer east face, and routes ranging from the strenuous Keyhole to serious technical climbs, it holds a central place in Colorado mountaineering and culture.
