Quick Answer
A minimum emergency shelter in winter should be windproof, waterproof, and provide insulation. It should be built with materials like tarps, space blankets, and branches. The shelter should be at least 6 feet tall and 8 feet wide.
Shelter Structure
When building an emergency shelter in winter, use a simple A-frame or lean-to design. This will provide a clear area for the door and keep the wind and snow off the structure. Use sturdy branches or poles (at least 2 inches in diameter and 8 feet long) to create the frame. Secure the structure with rope, twine, or wire. The A-frame design should have a slope of around 30-40 degrees to prevent snow from accumulating on the roof.
Insulation and Waterproofing
Line the shelter with a space blanket or a large plastic bag (at least 6 feet by 8 feet) to provide insulation and waterproofing. Use additional tarps or plastic bags to cover the roof and walls, securing them with rocks or weights. Ensure the shelter is completely sealed to prevent cold air from entering. Use snow or sand to fill gaps between the structure and the ground.
Additional Features
Include a door made from a sturdy branch or a piece of plywood, and a bed of leaves, pine needles, or snow to insulate the floor. If possible, use a car tire or a piece of plywood to create a makeshift floor. Keep the shelter away from trees, power lines, and other hazards. Use a warm hat, gloves, and a scarf to conserve body heat while inside the shelter.
