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. 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.
TO MAKE A DAKOTA FIRE PIT
* An aerated scheme for building a fire with little
or no smoke is known by camping and scouting experts
as the Dakota fire pit.
* As depicted in the illustration, there are two small
holes dug in the ground, one for the firewood the
other for a draft of air.
* Small twigs are stuffed into the fire hole and then
on top an easy burning layer of scrap is set. The
fire burns from the top downward, dragging air from
the "air hole" as it burns.
* Because the air passes inside the wood the CO gas
is consumed burning strongly and brightly and with
little or no seen smoke.
* The Dakota fire pit produces a low light signature,
reduced smoke, and is easier to ignite under strong
stone and concrete fire pits are very heavy and
are essentially locked in to wherever they are placed.
Both wood and gas may be used as fuel sources. However,
to make a fire pit only a hole is required in order
to safely contain a fire. This can be as simple
as digging a hole in the ground, or as complex as
hollowing out a brick or rock pillar.
