While it's Mount Everest that might get the most attention in terms of daring climbs, the walls of Yosemite have challenged many a rock-scaler over the years, and director Kristi Denton Cohen profiles several of them in her documentary Vertical Frontier. In addition to a historical chronology of the mountain, Cohen provides an in-depth look at the lives, obsessions, and equipment of the climbers who have dared to traverse the Yosemite.
