This reminds me of a short story in one of my readers in grade school. A kid, they never mentioned his age, got caught out while running his trap line with his dog. He used his snowshoes to dig a hole in the snow lined it with bows and more on a shelf to sleep on, built a fire made a hook from a link of trap chain using a Leatherman and caught fish. I won't bore you with the rest but it was very good and it sparked my interest in wilderness survival. I wish I could remember the title.
