What a tragedy, and even worse that it would have been so easy to prevent. I'm sure that once hypothermia set in his judgement was affected, and perhaps they didn't realize how much trouble they were in til it was too late. My heart goes out to the rest of the family. What a way for a vacation to end.

Hopefully something good will come of this; if nothing else perhaps it will force other families to take steps to learn some skills and make sure they're properly prepared.
