The point of a signal fire is smoke and contrast, not warmth.

Bear Grylls — Perfect Signal Fire

Step-by-step

  1. Pick a spot with a wide sky view — a ridge, clearing, or lakeshore. Not under trees.

  2. Build three fires in a triangle 25 m apart if you have the fuel; three of anything is a distress signal.

  3. Keep a pile of green boughs, wet moss, or damp grass at each fire, ready to dump on.

  4. Against snow use dark smoke: green vegetation. Against dark forest use white smoke: damp grass, moss.

  5. Only light when you actually hear or see a search — smoke ignored is smoke wasted.
