• Offers protection from the wind. • Is suitably placed in relation to your shelter (if any). • Concentrates the heat in the direction you desire. • Has a supply of wood or other fire burning material. c. Dakota Fire Hole. In some situations, an underground fireplace will best meet your needs. It conceals the fire to some extent and serves well for cooking food.

DAKOTA FIRE HOLE d. Aboveground Fire. If you are in a snow covered or wet area, you can use green logs to make a dry base for your fire (Figure 14-20). Trees with wrist-sized trunks are easily broken in extreme cold. Cut or break several green logs and lay them side by side on top of the snow. Add one or two more layers, laying the top layer logs in a direction opposite those of the layer below it.
