American daredevil Dean Potter took thrill-seeking to a whole new level Sunday, walking across a canyon almost 6,000 feet above sea level without a safety line.
Potter, from New Hampshire, completed the feat by crossing the Enshi Grand Canyon in central China's Hubei province, according to the BBC.
He tiptoed barefoot across the canyon on a one-inch thick rope in a technique known as slack-lining. The rope was more than a mile above sea level and Potter, 40, used no safety harness or safety net to complete his walk.
In video of the stunt circulated online, Potter, also a world-renowned base jumper and rock climber, can be seen wearing headphones and listening to music while making the trek.
Potter took about two minutes to walk the approximately 131 feet across the canyon.
Potter is in his element is the air: he free climbs, without ropes or a safety harness, walks highlines and BASE jumps.
"In some way, I wonder if it's healthy what I do," he said in a Feb. 2012 interview with ABC News’ “Nightline.” “I'm not even trying to say what I do is good. I go back and forth to asking myself those questions. Dean, man, is this healthy? You're obsessed on this thing that might kill you."
Potter holds records for free climbs on some of the world's tallest mountains, and holds a record for the longest flight in a suit that essentially mimics a flying squirrel.
"I'm forced to think about my mortality," Potter told “Nightline” in February, reflecting on his adventures. "I don't want to die until I'm an old, old man. ... I absolutely don't want to die falling. ... I am very afraid of that. But somehow I have an even deeper draw within me to keep going towards my fears."
