Another video with some avalanche information including your chance of survival should you get caught in an avalanche.
Here is an AMAZING video from a skier wearing a helmet camera getting caught in an avalanche. He is buried alive. If you watch this whole video without fast forwarding it will disturb you, but it is definitely worth it.
This video makes me think that this snowboard season I should take up skootching (aka cross-country snowboarding) to avoid the mountains and the associated avalanche dangers.
