Ian McIntosh was being filmed for a project called "Paradise Waits" when things went very, very wrong. The professional skier was in the Neacola range of Alaska when, during a run, he tripped over an unseen five-foot-deep trench.
From there, he fell 1,600 feet.
This is NOT what you want to happen. OMG.
Miraculously, he survived the fall without major injury.
