About the film
The Dawn Wall is a 2017 American-Austrian documentary film directed by Josh Lowell and Peter Mortimer about Tommy Caldwell and Kevin Jorgeson's successful attempt to create the first-ever big wall free climbing route—which they christened The Dawn Wall—on the historic southeast face of El Capitan in Yosemite National Park, which had hitherto only been ascended by aid climbing techniques first pioneered by Warren Harding who made the first aided ascent of the face in 1970.
