Catherine Howell Calhoun [1] (formerly Kitty Calhoun Grissom; born 1960) is an American mountain climber.
Calhoun was raised in Greenville, South Carolina. Her father, a corporate lawyer and a collateral descendant of John C. Calhoun, [2] sent her to an exclusive private school in Greenville where she excelled in sports, particularly hockey and skiing. [3] She began rock climbing through an Outward Bound course at the age of 18 and took up ice climbing at 19. [3] [4] She attended the University of Vermont and graduated in 1982 with a degree in recreation management. [3]
Calhoun's parents separated while she was in high school, and her younger brother Gib died by suicide shortly after she left college. [5]
Calhoun began her career in mountain climbing as an Outward Bound guide in Colorado after graduating from college. [3] She later became a guide for the American Alpine Institute, with whom she led climbs in Peru, Bolivia, Alaska, Argentina, and Nepal. [4] On a personal trip to Peru in 1984, she climbed Pirámide, Alpamayo and Qitarahu. [5] In 1987 she was the first American woman to climb Dhaulagiri in Nepal, [2] marking her first 8,000-meter peak, although she and her teammates had no Himalayan climbing experience. [3] [5] She subsequently received invitations to climb Mount Everest and join other high-profile expeditions, but she opted instead to lead her own expeditions with close friends. In recognition of her second 8,000-meter summit—an expedition she led up Makalu's highly technical West Pillar route—she was awarded the Robert and Miriam Underhill Award, the highest honor given by the American Alpine Club. [3] She was the first woman to climb Makalu, the world's fifth-highest mountain. [2]
In 1991 Calhoun relocated to Seattle and undertook a Master of Business Administration, which she completed in 1993. [3] After receiving her MBA, she founded Exum Mountain Adventures, a guiding company based in Salt Lake City. [2] In 2006, she climbed the Diamond Couloir on the south face of Mount Kenya with Jay Smith. [6]
Calhoun was formerly married to Colin Grissom, one of her climbing partners, with whom she has one son. She currently lives in Castle Valley, Utah. [4]
