Daredevil and tightrope walker Nik Wallenda crossed the Little Colorado River Gorge in Arizona last night, without using either a tether or a safety harness.
Wallenda walked along a quarter-mile stretch of two-inch steel cable, 1,500 feet in the air.
Wallenda wore elk-skin shoes to help him grip the steel cable. He was outfitted with two cameras that allowed viewers at home to watch the walk from his perspective.
** Wallenda, a seventh-generation tight rope walker, became the first tight rope artist to walk over Niagra Falls on a high wire when he accomplished the feat in 2012, bringing him his seventh Guiness world record.
