Don't Get Lost

In a level open space, drive a stake into the ground.
Mark the tip of the shadow that the stake casts with a small rock.
Wait at least ten minutes, and place another rock at the tip of the shadow.
The line joining the two will always run East-West, no matter what time of day or year.
