can shadows be used as guidance?

[iamah]

I'm wondering if the shadows change position or are always at the same direction? If not it could be useful for guidance

[Ornery]

Yes, you can use them for guidance. They begin the change a bit when you get into/near the darkness, but not enough to lose your way if you're using them like a compass.

[Potjeh]

They always point north.

I made some tests, the results were not encouraging. I'm sticking with landmarks for now.
