He did it.
Nik Wallenda, known as "The King of the High Wire," crossed a high wire spanning the Grand Canyon, without using a harness.
The tightrope act was 1,500 feet above the Little Colorado River. Wallenda kissed the ground after he finished the dangerous walk.
In 2012, Wallenda became the first person to tightrope walk directly over Niagara Falls from the U.S. to Canada at a height of 200 feet.
The 34 year-old Wallenda said the event honored his great-grandfather Karl Wallenda, who died after falling from a tight rope in Puerto Rico in 1978.
