The Dakota fire hole is a clever survival fire technique that leverages principles of physics to create an efficient and concealed fire. By digging two connected holes—one for the fire and a smaller one for air intake—it maximizes the efficiency of combustion. The intake hole allows air to flow through a tunnel into the base of the fire, supplying it with a continuous stream of oxygen. This airflow, driven by convection, creates a hotter, more efficient burn, reducing smoke and fuel consumption.
