About 9 years ago I was involved in one where 3 people got buried. We dug two out, but by the time we got Dan out it was too late. He was under for almost 10 minutes. Tried CPR on the hill to no avail. It was the most sobering feeling I have ever felt. FYI, he was heading up the hill when the snow, way above him, gave away and he took it head on. No avy pack would have saved him as they figure he was winded by the snow and then burried. Never want to have that experience again, so we avoid the open terrain now. The snow was packed like a rock and you could never move any of it by hand. Some of the guys left their shovels on their sleds and when we started digging, their machines were way at the bottom of the hill, and the guys were at the base. That is when doo had the shovels under the hood and everyone thought it was a good place for it. Now we all carry our avy equipment on our backs at ALL TIMES. I will never forget it.
