It is easy to make your own stove with a metal box or container. You must also keep an open space in the side and top of your shelter for fresh air to come in and smoke to escape. The heat of the desert is just as deadly as the Arctic cold. Many layers of thin clothing are warmer than single layers of thick clothing. Begin building your shelter five hours before sunset.
Natural shelters work just as well.
Choose a safe location away from avalanche or flood areas. A good location is a dry, sunny and flat area near a source of water and firewood. You will also need a hole at the top so the smoke can escape and a vent hole for fresh air.
