A professional skier's near death experience -- every single painful inch of a 1,600-foot tumble down a nearly vertical mountain face in Alaska -- has gone viral.

Ian McIntosh was not only strapped with a GoPro camera to capture his planned shushing down Alaska’s Neacola mountains, but he was also being tailed by a camera-equipped chopper hovering overhead. According to a post on the Teton Gravity website, McIntosh became a one-man avalanche after he slid into an unseen, five-foot deep trench.

With cameras rolling, the skier tumbled for more than 40 seconds, screaming and grunting from the impacts all the way down. The fact that he survived is both amazing and miraculous.
