THE DAKOTA FIRE HOLE HELPS AVOID WHAT?
1. High Temperatures
2. Carbon Monoxide
3. Smoke
4. Rain
(#3: Smoke)
The Dakota fire pit is an efficient, simple fire design that produces little to no smoke. Two small holes are dug in the ground: one for the firewood and the other to provide a draft of air. Because the air passes freely around the fuel, near complete combustion is achieved, and the result is a fire that burns strongly and brightly and with little or no seen smoke. The Dakota fire pit is a tactical fire used by the United States military as the flame produces a low light signature, reduced smoke, and is easier to ignite under strong wind conditions.

Yes @Barbscloud - your instincts were right: "The Dakota Fire Hole gets its name from the Native American tribe of the Dakota, who populated the area that is now North Dakota, South Dakota, Wisconsin and Minnesota. It is generally regarded that they used this style of fire to combat the local windy conditions and avoid the potential of starting grass fires." ( Bushcooking.com)
