Oh, I'm not directly professionally involved with the avalanche searches (unless I get called out for volunteer S&R). It's just a stupid waste of life, yes? And also of taxpayer's resources. They've finally started charging the extreme sport yahoos for when they need emergency extraction, and it's about bloody time. There's a difference between "avoidable" and "idiotic risk", and when people do the latter I don't have much sympathy if things go sideways.

Your scheme for fixing things is alas impractical, no matter how appealing. The plane routes tend to go over passes so far as I know (but I could be wrong), so those are already being managed, and they'd mostly just blow up people and put inconvenient holes in the roads.
