I beelieve that the learning curve for life outside the groomed slopes is going to have to be very steep this year. Casual trail bangers such as myself are not used to tree wells and avalanche warnings.
Of 12 ski deaths in
Western North America in the last month, 4 skiers were eaten by tree wells.
Edit 4-20-11: Excellent tree well rescue video here:
