Navigation - Directions
from the Sun's Shadow
By Robert C. Etheredge
You can use the shadow cast by a stick during the day to help determine
the East/West direction. This is more effective during the middle of the
day.
Place a stick around 3 feet tall in the ground as perpendicular as possible
(use string and a rock to line it up). Mark the end of the shadow with
a rock. Wait 15-30 minutes and place another rock at the end point of
the new shadow. A line connecting these two rocks runs approximately East/West.
