The shadow stick method

Though rescue experts suggest you should stay put and wait to be found when lost, there are times when medical necessity or a faint hope of being found means you’ll want to get moving. With any luck you will have a hunch as to whether salvation lies north, south, east or west. During a sunny day, ideally around noon, you can determine direction using the shadow stick method.


Prop up a straight stick (at least three feet long) so it stands vertically and casts a shadow on a flat, smooth area.

Draw a line between the two stones. This line will point from west to east, with the second stone you placed being the eastern terminus.
