[There are many other methods of establishing true north when you are in a pinch and don't know exactly where you are.... This is an easy one to remember.
That's a new method to me... thanks!
The shadow stick method I remember is: Plant the stick. Mark the shadow's end. Wait, say, 30 minutes. Mark the shadow's end. The line through the shadow's ends is supposedly true E/W. In the northern hemisphere, the first mark you made will be more Westerly than the second mark you made, so you will be facing North if you put your left toe at the first mark and your right toe at the second mark. It's spiffy that it doesn't matter what time of day you do this (or does it? Is it most accurate near noon?)
How does this method compare for accuracy with the shortest-shadow method?
