"Meet the people who pioneered modern rock climbing and those who are taking it in incredible new directions: the determined free spirits, vagabonds, and visionaries who take part in one of the West’s last truly wild experiences. Granite Frontiers: A Century of Yosemite Climbing brings visitors to the edge of infinity to experience the exhilarating rush and harrowing perils of this most extreme of Western adventures."
