I'm fairly confident that I could survive as long as I crashlanded near a cabin in which were stored winter clothing, snowshoes, a rifle w/ plenty of ammunition, an axe, a saw, and plenty of salt, beans, flour, suger, coffee, and vitamin C tablets. A couple of jugs of moonshine wouldn't hurt either.
I wonder what I would be doing up there without at least some of these items though?
