It's said you can find north by looking at moss on a tree, that it only grows on the North side. I think someone forgot to tell this tree:
I'll show you North!

By looking at the exif information for this picture, you know this is a dark place. It's in a canyon, and probably the tree doesn't get a lot of direct light, certainly not in the winter. So, all directions seem to be North.
