Primitive Shelter
Exposure kills faster than hunger. Shelter is about trapping still air, shedding water and blocking wind—not building a cabin.
Scenario
Temperate forest at dusk; temperature dropping; light rain starting.
Best first move: Debris hut
A tight debris hut with a thick roof beats a pretty lean-to that leaks. Site selection first—then pile insulation.
Why it matters
Under the Rule of Threes, shelter and fire share top urgency. A bad night of heat loss ruins tomorrow’s water and travel decisions.

Matches shelter type to biome and weather; manages heat, moisture and safety overnight.
FAQ
Should I sleep in a cave?
Only after checking for animals, rockfall, flooding and bad air. Improve the entrance windbreak and keep bedding dry.
How big should a debris hut be?
Barely larger than your body. Small spaces warm with body heat; cathedral ceilings waste warmth.
