Hilaree Nelson is one of the strongest high alpine skiers in the world. A veteran of the prestigious ski mountaineering scene in Chamonix, France, she's ridden from the summit of Tibet’s Cho Oyu, climbed and skied in Bolivia, Argentina, and the Baffin Islands. But last year, she put an emphatic stamp on her career when she skied the Lhotse Couloir, a perilous project she completed with partner Jim Morrison. The prized virgin line featured a 2,000-foot couloir amid a 7,000-foot descent. And, oh yeah, she’s the first woman to climb two 8,000-meter peaks in 24 hours (Everest and Lhotse, and yes, that was a different trip). In 2018, Nelson was named National Geographic’s Adventurer of the Year. She's done all this while raising two sons.
