A formidable alpine climber, Beckey is unofficially recognized as the all-time world-record holder for the number of first ascents credited to one man. Beckey's most famous climbing feat is his triple ascent of Alaska's Mounts McKinley, Deborah, and Hunter in 1954. His 3-volume Cascade Alpine Guide, published by The Mountaineers, is considered the definitive resource on the mountains located between the Columbia River and the Canadian border.
