Start preparing your camp well before dark. Look for a natural shelter, such as a rock overhang or a thick stand of evergreens. The site should be dry and well drained, and protect you from the wind. Ideally, it also should be near water and plenty of firewood.
If no natural shelter is available, pick an area with materials nearby to build a lean-to or debris hut.
A lean-to is constructed by leaning branches against a horizontal support to form a frame for a roof. Be sure to orient the opening away from the wind. Cover the frame with evergreen branches to block wind or precipitation. Leaves and twigs are another option. If you need additional protection, you can add side walls.
Build your fire where its heat will radiate into the shelter. Your sleeping area should be located between the shelter wall and the fire.
