Quick Answer
To create a smoke signal for rescue in a forest, build a fire, add green branches to produce a thick smoke, and use a chimney effect with rocks to direct the smoke into the air. Use three to four green branches at a time to maintain a steady smoke column. Aim for a fire that is at least three feet tall.
Building the Fire
To create a smoke signal, start by building a fire that is at least three feet tall. Use hardwoods such as oak, maple, or ash for the fire, as they burn hot and produce a good amount of smoke. Keep the fire small at first, and gradually add more fuel to increase the size of the flames. Once the fire is burning well, add green branches to the fire to produce a thick smoke.
Creating the Smoke Column
To create a smoke column, use green branches such as fir, pine, or spruce. These branches contain more moisture than other types of wood, which makes them produce a thick, white smoke when burned. Add three to four green branches at a time to the fire, and wait for them to burn completely before adding more. This will help maintain a steady smoke column.
Directing the Smoke
To direct the smoke into the air, use a chimney effect with rocks. Place rocks around the fire in a circular pattern, with the largest rocks on the outside and the smallest rocks on the inside. As the smoke rises, it will be funneled through the rocks and directed upwards. This will help the smoke signal travel further and be more visible to potential rescuers.
