Dean Potter has traversed unfathomably high slacklines across the world, but this one is a real heart-stopper.
He takes on a 100ft long wire over Taft Point in Yosemite National Park, California – with NO HARNESS. At 3,200ft above sea level, there’s a pretty hefty drop awaiting him below.
Will he make it? Watch and see. Guaranteed to leave you clinging onto the edge of your seat.
