For another really hair-raising survival story, actually they didn't survive, try Death in the Barren Lands.  Originally the diary of Edgar Christian, a young man who went to live in the NW Territories with an uncle and another guy to trap for the winter.  His original account is called Unflinching.  They started out on a grand adventure, everything going great, then winter set in, the traps didn't produce and there wasn't any game for meat...they found Edgar's diary in the wood stove where he left it before he passed away, the last of the three to die alone in the wilderness.  It was just a few weeks before spring would have changed the situation for him.   :'(
