Some sports are inherently more dangerous than others. Skiing is already a pretty dangerous sport, but when you start taking on large, steep, rocky mountains you seriously increase the odds you might hurt yourself. Ian McIntosh is a veteran pro skier, but even the pros make mistakes. While skiing down the Neacola mountains in Alaska, McIntosh made a miscalculation that left him falling 1,600 feet down the mountain! Thankfully, he survived. This terrifying video has gone viral with over one million hits!
