A tightrope daredevil has completed a walk that took him quarter of a mile over the Little Colorado River Gorge in north-eastern Arizona.
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 so that he could get "the rhythm out of the rope".
"Thank you Lord. Thank you for calming that cable, God," he said about 13 minutes into the walk.
Wallenda didn't wear a harness and stepped slowly and steady throughout, murmuring prayers to Jesus almost constantly along the way. He jogged and hopped the last few steps.
The event was broadcast live on the Discovery Channel.
Winds blowing across the gorge were expected to be around 30 mph. Wallenda told Discovery after the walk that the winds were at times "unpredictable" and that dust had accumulated on and around his contact lenses.
"It was way more windy and it took every bit of me to stay focused the entire time," he said.
Wallenda, 34, is a seventh-generation high-wire artist and is part of the famous Flying Wallendas circus family - a clan that is no stranger to death-defying feats. His great-grandfather, Karl Wallenda, fell during a performance in Puerto Rico and died at the age of 73. Several other family members, including a cousin and an uncle, have perished while performing wire walking stunts.
Nik Wallenda grew up performing with his family and has dreamed of crossing the Grand Canyon since he was a teenager.
Sunday's stunt comes a year after he traversed Niagara Falls earning a seventh Guinness world record.
