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.
He was only buried for 4 and a half minutes which is incredibly short. I cannot stress these next sentences enough; that in and of itself to be unburied in ONLY 4:28 is miraculous if you have any understanding of being caught in an avalanche and what it takes to be found. It could literally be some kind of “world record” just on how good the guide and supporting cast of other skiers was in getting to him. It also shows why you should ALWAYS be going with people trained in avalanche rescue / first aid….as well as why you’d want to be going with a guided heli operation. Sure this was terrifying for him, but he would’ve probably been dead if not for going with a guide.
