13 El Capitan at Yosemite National Park-ThinkstockPhotos-531042384.jpg


El Capitan in Yosemite National Park rises nearly 3,600 feet above the valley floor (7,500 feet above sea level) making it one of the most prominent features in the park. BASE jumping is illegal in national parks but a few people have been known ignore the rule. See BASE jumping pioneer Carl Boenish as he  jumps off El Capitan here. There have been calls to remove the ban on BASE jumping in the park.
