A skier gets buried in an avalanche, but is rescued only four and a half minutes later. Everything gets caught on film with the video camera attached on the victim's helmet.
This was a decent sized avalanche. 1,500 feet the dude fell in a little over 20 seconds. The crown was about 1 - 1.5m. The chute that he got sucked through to the skier's right was flanked on either side by cliff bands that were about 30m tall. He luckily didn't break any bones and obviously didn't hit anything on the run out.
