Yeah, map it out and stick to the basics. Use a lean, angled frame—just a few sturdy sticks for the ribs. Cover it with a thick layer of packed snow or packed earth; it’s a good insulator and doesn’t need much work to shape. Then slap on a blanket of dry leaves or packed moss over the top for extra windbreak. Keep the opening small and face it away from prevailing winds. That’s the quickest way to stay warm without digging a lot of trenches or hauling heavy gear.
