See the Nail-Biting Video of a Man Tight-Rope Walking Over a 3,000 Foot High Canyon

If circus tight-rope walkers amaze you, Dean Potter, a highliner, will stun you.

Highlining is a version of extreme tight-rope walking -- without a balance pole. In one of Potter's latest highlining expeditions, he crosses Taft Point at Yosemite National Park in California, potentially setting a record for highlining.

Watch Potter as he makes his way without any safety measures across this 100-foot rope above more than 3,000 foot drop:

The Post Game reports that Potter is also known for base jumping and other extreme sports. Here's more on The Post Game's thoughts:

That video is all kinds of "Nope." Potter takes two steps over the gorge, and our fingers are already out, testing the wind for the slightest shift in direction. No way, no how, would you ever find any of us even standing on the ledge looking over, let alone walking out. We applaud you if you were even able to watch the whole video without hitting pause.

The New York Times a few years ago (via The Post Game) reported that Potter learned this extreme tight-rope walking from "homeless man who wrote books on quantum physics." From the Times' account, Potter is no stranger to Yosemite. In 2002, he became the first man to free climb El Capitan and Half Dome in less than a day.

At the time, the Times reported Potter as saying he "a little helpless" when he gets to the middle of the rope.
