Quick Answer
When lost in the wilderness, use visible and audible distress signals to alert potential rescuers, such as building a fire, using flares, and making noise. Three fires, spaced 100 yards apart, are most effective at night. Whistle three short blasts, then pause, then whistle three more blasts.
Choosing the Right Signals
When lost, it’s essential to use the right distress signals to maximize the chances of being rescued. For ground-to-air signals, use high-visibility items like brightly colored clothing, mirrors, or shiny objects to reflect sunlight towards any passing aircraft. This method is particularly effective during daylight hours.
Building a Fire
A fire is one of the most effective ways to signal for help, especially at night. Build three fires, spaced 100 yards apart, using dry, flammable materials like twigs and leaves. This creates a visible signal that can be seen from a distance. Keep the fires small and controlled to avoid attracting wildlife or causing a forest fire.
Making Noise and Using Flares
In addition to visual signals, making noise can also help alert potential rescuers. Use a whistle to signal for help, following the International Distress Signal Code: three short blasts, then a pause, then three more blasts. You can also use flares, which can be seen from a distance and are effective during both day and night. However, use flares sparingly, as they can be hazardous if not handled properly.
