If you encounter a fire Do not try to outrun it. Windblown fires move extremely fast, and embers carried on the wind can ignite more fires miles away ahead of you. Always stay upwind of a fire. If you can't move upwind due to a cliff or other topographical boundary, move away from the fire at a right angle. Wind controls the direction a fire will take.
Fires commonly move up hills because heat rises.
If you have a canoe with you, put on your life vest, flip the boat over and hang out underneath it, where you can breathe cool air until the fire passes. If there's no open water around, look for a wet, open, marshy area. Move to the center of the area and lie down. After the fire passes, continue to exercise caution. Burned trees can fall with a slight gust of wind, and you could burn the soles right off your boots by stepping on hot embers.
