Cassidy Randall, an award-winning writer who tells stories on the environment, adventure, and people who expand human potential, discusses what cultural barriers women adventurers had to endure in the 1970s, how the world reacted after Grace Hoeman and her team completed their climb, and how we can talk to our kids about this incredible but unknown accomplishment. Cassidy's new book is Thirty Below: The Harrowing and Heroic Story of the First All-Women's Ascent of Denali.
