Also true North is perpendicular to the shadow path on the ground at any time of day. You don't need an accurately vertical stick for this, you don't have to wait until noon, and you only need two points.Plant a tall stick or pole into the ground. Hang a plumbline from the top of the pole to make sure the pole is perfectly vertical.
On a sunny day make a mark on the ground where the shadow of the stick appears. Place a mark or stone on the ground where the tip of the shadow appears. (This must be done on level ground.)
Do this many times over a couple of hours before midday and after midday.
Find the shadow that is the shortest. This shadow will be aligned with true north and south.
look upaha Thanks.... , but what's meaning of " the deviation in your local area." ?? ,,,,, and please if you can explain method number 2
with my deepest thanks

That's what the survival manuals say, everything from the Boy Scout stuff to the Department of Wildlife's Winter Survival Guide for Hunters. Even the Air Force's Survival Guide that is issued to pilots.Also true North is perpendicular to the shadow path on the ground at any time of day. You don't need an accurately vertical stick for this, you don't have to wait until noon, and you only need two points.
