It has to do with the thing about "when you start feeling warm, you're in trouble" rule with hypothermia and frost bite. Never heard the technical name, but it sounds like a scary, scary place.

I hadn't heard he was close to a camp. *shakes head* I kinda figured they'd find him within a few hundred yards of a main road or a building. Too often it is so close and so far to safety. That they held out as long as they did is a sign they did things right once they got stuck- he just had bad luck when he went to Plan B, and there is no other way to describe it that I can think of.

May his next life be a joyous one and as well lived as this one.
