Nik Wallenda completed a historic high-wire walk on a 2-inch steel cable over a section of the Grand Canyon on June 23. Wallenda, the self-described "King of the High Wire," took 22 minutes and 54 seconds to walk 1,400 feet across the crimson-hued canyon with just a distant ribbon of the Little Colorado River beneath him. The event was broadcast live around the world. Here are some images of Wallenda and other daredevils in action.
