When looking for water, stand still to listen for indications that there is water in the area and always head downhill because run-off water collects in low-lying areas. Swarming insects and the direction birds are flying in the morning or evening can also be a good indicator. Places where animal tracks cross are a sign that there could be a common watering hole in the area. In the forest, look for damp patches of earth or mud and dig down about a foot, also making the hole a foot in diameter. The water will collect at the bottom of the hole but needs to be filtered and purified before drinking.
