How to Construct a Thermal Shelter in the Wilderness?

Site Selection

When selecting a site for a thermal shelter, look for a location that provides natural protection from wind and precipitation. A south-facing slope or a spot near a body of water can be ideal, as they often receive more sunlight and have a more consistent temperature. Avoid areas with standing water or where water may collect, as they can be prone to flooding.

Building the Shelter

Begin by creating a windbreak by placing branches and leaves around the shelter. This will help to reduce wind chill and keep you warm. Next, use a tarp or space blanket to cover the top and sides of the shelter. Secure the tarp or space blanket with rocks, sticks, or snow anchors, making sure to leave a small opening for ventilation. If possible, use a natural shelter such as a cave or overhang, and line it with branches, leaves, or a tarp to keep the wind and rain out.

Additional Tips

In extreme cold weather, it’s essential to stay dry and warm. Remove any wet clothing and shoes, and use dry clothes and a hat to stay warm. If you don’t have a tarp or space blanket, use a snow trench or a quinzhee shelter as an alternative. A snow trench can be created by digging a shallow trench in the snow and covering it with branches and leaves. A quinzhee shelter can be built by piling up snow and then hollowing it out to create a shelter.
