The odds of surviving an avalanche must be very slim. But given these options, I'd reject # 1, because that's almost like surfing the avalanche into oblivion (my own oblivion, that is).

I'd reject #3, because that seems like I'd just be rolling with the snow, as it inevitably gets deeper and deeper. Instead of letting it "carry" me, I'd be letting it "bury" me.

That leaves #2. It sure won't be easy, but I believe it will increase my chances of survival, even if every so slightly.
