Stick compass
by Matt
(Colorado)
Take a straight stick or branch with few defects. It needs to make a straight shadow. Then place it in the ground so it stands up straight. When the sun comes up in the morning it shows you where true east is, and the shadow on the stick gives you west. If you stand with east on your right and west on your left you are facing north, and south is to your back.
