If you find yourself lost and need to get your bearings without a compass, do the following. Find a sunny location. Drive a 3 foot long stick in the ground. Place a rock where the tip of the stick’s shadow falls on the ground. Wait about 20 minutes and then place another rock on the spot where the tip of the shadow has moved. The first rock indicates the west end of a line running between the two rocks; the second marks the east end.
