El Capitan

El Capitan is a vertical rock formation in Yosemite National Park, on the north side of Yosemite Valley, near its western end. The granite monolith is about 3,000 feet (914 m) from base to summit along its tallest face and is a world-famous location for big wall climbing, including the disciplines of aid climbing, free climbing, and more recently for free solo climbing.
