Hosted by veteran alpinist and climbing historian Christian Beckwith, Ninety-Pound Rucksack is a podcast about the US Army’s 10th Mountain Division and the dawn of America’s ca. $1T outdoor recreation industry. 

The 10th was an unprecedented unit of World War II climbers and skiers who trained for more than two years in the Colorado Rockies to fight the Axis powers in extreme cold and mountainous terrain. Not only did the Division’s insertion into the war catalyze Germany’s surrender; post-war, its veterans developed ski areas across America, started companies like NOLS and Nike and electrified the fields of conservation and wilderness education.  

Informed by an advisory board of the Division’s foremost experts, Ninety-Pound Rucksack examines the stories that made the unit famous as well as those history has forgotten. Equal parts real-time research, intimate conversation and revelatory journalism, the podcast illuminates the transformative power of the mountains to forge a collective identity among the mountain troops—and to ignite a passion for the outdoors that reshaped American society in the process.


The founder and board chair of The Teton Climbers’ Coalition, Christian Beckwith has spent more than thirty years immersed in the world of alpinism. He started his first climbing organization, The Wayward Mountaineers, and The Mountain Yodel, a climbing ‘zine, soon after moving to Jackson, Wyoming, in 1993. In 1996, he became the youngest person to edit the world’s premier mountaineering journal, The American Alpine Journal. In 2002 he co-founded Alpinist Magazine, an archival-quality climbing quarterly that Reinhold Messner called “the greatest climbing magazine in the world today.” More recently, he started the surfing, skiing and climbing extravaganza, The Alpinist Film Festival; coordinated the Teton Boulder Project, which developed a Jackson Hole bouldering park to honor Teton pioneers; launched Outerlocal, a social media website for adventure athletes; developed the Town Pump bouldering series; and founded SHIFT, a 501c3 non-profit organization dedicated to the advancement of nature as a social determinant of health; and launched and directed AlpinFilm. He has made expeditions to Kyrgyzstan, Alaska, Peru and Tibet, skied the Grand Teton half a dozen times, and established numerous first ascents and descents around the world. In 2023, he was inducted into the 10th Mountain Division’s Warrior Hall of Fame for services rendered to the Division. He lives in Jackson, Wyoming, with his wife and daughter.
