Arlene Blum is a legendary trailblazer by any measure. Defying the climbing establishment of the 1970s, she led the first teams of women on successful ascents of Mt. McKinley and Annapurna, and was the first American woman to attempt Mt. Everest. In her long, adventurous career, she has played a leading role in more than twenty expeditions and forged a place for women in the perilous arena of high-altitude mountaineering.
