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.
A fire pit or a fire hole can vary from a pit dug in the ground to an elaborate gas burning structure of stone, brick, and metal. The common feature of fire pits is that they are designed to contain fire and prevent it from spreading.
Many homeowners are using fire pits for warmth, entertainment and cooking or as focal points for an outdoor living space. Some recent trends have included the modification of compression tank ends to create a fire bowl that can be placed in the ground or on legs.
Many people opt for a mobile fire pit that can be moved around to various locations. Movable fire pits are certainly less expensive than a built-in pit, come in a wide variety of designs, and have the added benefit of portability. The primary drawback, however, is that a movable fire pit tends to only last a season or two before the materials begin to deteriorate.
