I find it hard to believe that Jamie Pierre didn't have any formal avalanche training. He's been filming in the backcountry for years. Pretty sure, due to the guides and others he's been out with, he's at least been through basic avy awareness. Regardless, it looks like a lot of bad decisions by lots of people in Wasatch yesterday. Unfortunately it took the life of one of the more entertaining snow athletes around.
12 reported human caused slides on the same day he died and 2 large natural slab slides, so yea no a good day to be out riding in uncontrolled areas.
