Photos: Nik Wallenda walks across canyon on high wire

Aerialist Nik Wallenda completed a tightrope walk that took him a quarter mile over the Little Colorado River Gorge in northeastern Arizona on Sunday.

Wallenda performed the stunt on a 2-inch-thick steel cable, 1,500 feet above the river on the Navajo Nation near the Grand Canyon. He took just more than 22 minutes, pausing and crouching twice as winds whipped around him and the rope swayed.
