Longs
Peak
A survey crew under geologist John Wesley Powell made the first recorded summit in 1868, approaching from the south rather than the sheer east face. The peak's name honors Major Stephen Long, who spotted the Front Range from the plains in 1820 but never came near it; the Arapaho already knew it and neighboring Mount Meeker together as Neniisotoyou, roughly "the two guides," landmarks for travelers across the region. Addie Alexander reached the top in 1871, the first woman recorded to do so.
In January 1925, Agnes Vaille and Walter Kiener made the first winter ascent of Longs Peak's East Face; on the descent she fell near 13,000 feet, then froze to death from exhaustion before Kiener could bring help, and would-be rescuer Herbert Sortland also died. A stone shelter built near the Keyhole in 1927 still bears her name. Most climbers today take the Keyhole Route, a roughly 15-mile round trip gaining close to 5,000 feet through the Trough, the Narrows and the Homestretch.
