Dacota Fire Hole

The Dakota fire pit is an efficient, simple fire design that produces little to no smoke. As depicted in the illustration, two small holes are dug in the ground: one for the firewood and the other to provide a draft of air. Small twigs are packed into the fire hole and readily combustible material is set on top and lit. The fire burns from the top downward, drawing a steady, laminar stream of fresh air from the air hole as it burns. Because the air passes freely around the fuel, near complete combustion is achieved, the result being 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.

Scheme

Lately I’ve become a fan of Primitive Technology, and started watching similar channels in Youtube. And one beautiful day I suddenly felt the urge to go and spend some time in the mountains. So – in the car I went and straight to Studenets – about 30 kilometers from Plovdiv.

I had some sausages, which I wanted to roast. So – since it was really windy – it was time to test the Dakota Fire Pit into action. The basic idea is to dig a hole, in which the fire will be lit, and to create another hole, to supply the fire with oxygen.

Well, considering the tools I had was a knife, I had to improvise. So I dug a big enough hole (using a branch, and removing the dirt by hand), and then I dug a small canal, which was the oxygen supply. Then I covered part of the canal with branches, and covered the branches with dirt. Since it was really windy – I built a wall, using twigs, “hammered” into the ground and some thin branches to connect them. And then I covered the “wall” with more dirt.

Well, the end result was a bit far from the original idea, but still did the trick:

Well, all I had to do was to gather some thin branches and create skews. Unfortunately – being in a hurry, didn’t find peppers, so I used sausage and onions for the skews. A pro tip – in order for the onion not to split – create a triangle hole, wide enough for the “skew” with a knife – this way it will remain intact.

The downside of this is you need more time to prepare the fireplace. Although it has multiple advantages:

  • generates enormous heat for the little firewood I gathered
  • has useful walls, which can be used to place grill, or skews
  • produces less smoke
  • not affected by wind
  • safer – it’s harder to create fores fire
  • really easy to extinguish – you just return the dirt back into the hole and collapse the air hole
The pit is ready
