Daredevil's impressive canyon tightrope walk
Florida aerialist Nik Wallenda's successful tightrope walk took him a quarter mile over the Little Colorado River Gorge in northeastern Arizona on Sunday, near the Grand Canyon. He performed the stunt on a 2-inch-thick steel cable, 1,500 feet above a river, with no harness. The walk took just more than 22 minutes.
