Grant Statham gave a great TED talk recently on risk in avalanche terrain that has been circulating around the avalanche community lately. Grant has spent a lifetime climbing, skiing and guiding in extreme terrain around the world and he has spent the past 10 years or so working as a risk management specialist for Parks Canada. Grant does a great job of explaining risk and hazard and how it relates to travel in avalanche terrain in this TED talk.
