There are two kinds of shadows to look out for in camouflage.

One is the concealing shadows cast by objects or formations on the ground. From the air these shadows appear so dark that a vehicle parked within them has a good chance of being unnoticed. Other camouflage measures should often be taken, but making use of these shadows is an important primary step in concealment. In the northern hemisphere, the north side of an object higher than the vehicle is the best side to park on, and the east and west sides are each dangerous for half a day.
