Nik Wallenda successfully walked the 1,500 feet across the Colorado River Gorge in Arizona on Sunday. The high-wire daredevil, famous for similar walks like the one he did at Niagara Falls, made the precarious trek live on television and without a net or safety line.
The walk took Wallenda 22 minutes of edging his way along the 2-inch-thick cable.
