This clip, which was captured by a helmet-cam, makes me never want to set foot on a snowmobile.

A group of guys are riding along, going up and down a large hill, and then bam: one triggers an avalanche and a rider is completely lost below a deep blanket of white snow.

Luckily, the victim here lives to tell the story, but that must have felt like an eternity for him. What is perhaps the scariest part of this whole thing is that he could have easily been lost altogether under the snow, but the other riders (thankfully) knew where to dig.
