Find food... There are lots of edible roots and berries, but watch out! Some are poisonous. Only eat them if you are sure they are safe. The best, and most reliable.
13. Try to make contact. Build big, unnatural looking shapes using bright colors and shiny things. Use a radio, if available, to contact possible rescuers. Use signal mirrors, fires and flashlights and whatever else to draw attention to yourself. This can be done while you wait.
