My condolences to families and friends.

In recent years BC snow mobile clubs have done a good job at providing avalanche training to their members.  Perhaps hiking clubs can reach out to the avalanche groups and make such training available to their groups.

A cornice breaking away is just another type of avalanche and has caught numerous people who attempt to enjoy the view in a mountain top.

Again my condolences. I had a friend & fellow worker die in an avalanche.
