The Dawn Wall
Tommy Caldwell and Kevin Jorgeson etched their names into climbing lore on Wednesday by successfully completing a 19-day free-climb of the Dawn Wall on El Capitan. The route up the mostly smooth granite face is widely considered to be the most difficult free-climb in the world. A free-climb means that ropes are used only to catch a climber’s fall — not to aid the ascent.
