So, I guess we would find you frozen to a tree like Hatchet Jack?
Your shelter is only limited by your imagination.
Crawling under a pile of leaves is all a man would have to do to live in cold weather.
If you are above the tree line like a Marmot Slayer would be, You might be a tad on the screwed side.
I don't recall who Hatchet Jack was, but the frozen to a tree part tells the pertinent part of the story!
Nice thing about the rock heated trench is if it doesn't work out, the search party need only fill it in and cover the remains. :shocked2:
Here's one possible scenario; Elevation 9,500 feet. a windswept high mountain "park". Mostly short grass prairie with some trees on the ridges mixed evergreen and aspen. Trr cover is sparse. Not much snow falls here so the ground is frozen solid and rocky to boot. Night time temps are in the -10 to -35 range. Your equipment is whatever you would pack for a day hunt. You don't choose to spend the night here but even though your car is only three miles away, you have broken your ankle. You need to survive at least one night and maybe more. Whatta ya do?
