Arlene Blum defied the climbing establishment of the 1970s by leading the first all-female teams on successful ascents of Mt. McKinley and Annapurna, and was the first American woman to attempt Mt. Everest. At the same time, her groundbreaking scientific work challenged gender stereotypes in the academic community. With candor and humor, Blum recounts her journey from an overprotected childhood to the tops of some of the highest peaks on Earth, and to a life lived on her own terms.
