Quick Answer
Ground burns can be used to purify water, create a fire lay, and provide a source of warmth in extreme cold. They can also be used to trap small animals or signal for help. This technique is essential for wilderness survival.
Creating a Fire Lay
A ground burn is a fire pit dug into the ground, typically 10-15 inches deep and 3-5 feet wide. Create a fire lay by digging a shallow pit in the center of this area. Fill the pit with tinder, kindling, and larger logs, arranging them in a teepee shape. This design allows for good airflow and efficient burning.
Purifying Water
To use a ground burn to purify water, dig a shallow pit nearby and fill it with water. Place hot coals or embers from the fire lay in the pit, creating a makeshift solar still. As the water heats up, the impurities will evaporate, leaving clean drinking water.
Trapping Small Animals
A ground burn can also be used to trap small animals, such as rabbits or squirrels. Dig a shallow pit in the path of a likely animal route, and line it with twigs and leaves. Place bait at the entrance of the pit, and light the ground burn nearby. The animal will follow the bait into the pit, where it can be easily caught.
