Chantel Astorga, born in 1985, an American rock climber, mountaineer, ski mountaineer and avalanche expert in the State Transportation Department. Chantel used her knowledge of techniques enabling fast climbing which she mastered in the rescue services of the Yosemite Valley (Yosemite Valley Search & Rescue) for quick ascents as well as for combination route and solo climbs on great walls of the Valley. In 2011 with Libby Sauter she broke the female speed record of climbing The Nose on El Capitan (10 hr 40 min.). In 2012, this time with Mayan Smith-Gobat, she set a new record: 10 hr 10 min. A few days later together with Mayan she made a one-day ascent of The Nose and Regular Northwest Face (Half Dome). During this climb the girls significantly beat the record on the Nose, doing it in 7 hr 26 min. In 2014 Chantel returned alone to “the most famous route in America”, climbing it in 24 hr 39 mins. It was, of course, another female record. The American did not, however, intend to pursue her ambitions only on rocky big walls, her dreams were much bigger. When she was working as a guide on Denali in the years 2008-2011 she looked at the legendary walls and routes in the area. In 2014 with Jewell Lund she made an ascent of Polachrome on Mount Huntington. A year later, emboldened by an easy success, the ladies attacked a much more challenging line- Denali Diamond. The first female ascent became a reality after four and a half days of climbing. In 2017 Chantel returned to Denali with Anne Gilbert Chase. The team climbed in a great style the extremely difficult route-Slovak Direct. Last autumn Chantel and Anne, together with Jason Thompson established a new route on the South-West Face of a six-thousander Nilkanth in the Garhwal Himalayas. The jury of the Piolet d’Or awarded them for this climb, mentioning also the outstanding, purely feminine ascent of the Slovak Direct.
