You fearlessly tromp in a westerly direction for maybe a hundred yard when you come to a wall covered in vines. Pushing and pulling them aside you find granite underneath. Then you think to look up. A sheer cliff rises several stories before you. While the vines and plant life have found cracks and crevices to cling to there are no foot or hand holds suitable for your large, human appendages. There is no west.

Which way now fearless adventurer?

I guess I'll go south.

To the east then, ad the rising sun.

I'll go north.
