Dakota Fire Pit.
The Dakota Fire Hole Pit gets its name from the Native American tribe of the Dakota, who populated the areas that are now North Dakota, South Dakota, Wisconsin and Minnesota. It was developed to combat the windy conditions on the Great plains and to avoid the potential of starting grass fires. The Dakota fire pit is a tactical fire used by the United States military, the flame produces a low light signature, reduces smoke, and is easier to ignite in strong winds.
Dig two holes about 2 feet apart, both between 6-12” wide, and about 12” deep. Then dig a tunnel between the two. In the hole that is upwind lay a fire. In the hole that is downwind dig an angle that is facing the wind. That will maximise airflow in the tunnel. This fire will burn very hot. So if fuel is a limited resource, don’t use this set up.
