These take more time to build than open shelters (at least three hours), but your efforts will be doubly rewarded. Not only can the shelter be warmed by a small fire, reducing the need to collect a huge pile of wood, but the firelight reflects off the walls, providing cheery illumination for sitting out a long winter night.
This forerunner of the tepee remains the quintessential primitive shelter-"sturdy enough to blunt prevailing winds, weatherproof, quickly built for nomadic hunters, but comfortable enough to serve as a long-term home. It can be partially enclosed or fully enclosed and vented to permit an inside fire.
Step 1: Tilt three poles together in tripod form and bind them together near the top. If you can find one or more poles with a Y at one end, tilt the others against the crotch, eliminating the need for cordage.
Step 2: Tilt other poles against the wedges formed by the tripod in a circular form and thatch, leaving a front opening and a vent at the top for smoke.
