Watch an Avalanche From Inside

This video is incredible, and scary as hell. Definitely a keeper if you've a) been on a 38 degree slope and wondered how set the layers were and/or b) in movies, you hold your breath while the protagonist is underwater. A back-country skier in Alaska triggers an avalanche seconds after starting his run, and fortunately his mates dig him out (all videoed from his helmet cam, complete with sounds of him gasping for air) less than 5 minutes after he goes in. Can you watch the whole thing until they get to him? I couldn't, and it wasn't out of boredom that I stopped it.
