I dug the rock I spoke of earlier with the x if that is what you are referring to, It was more like a rock bank beside a tree, but after pulling out MANY rocks, and much digging, There was nothing. This is how I concluded it must be telling me to keep going in the same direction.
I have a question, These sights are Quite a far distance apart. I found the rock pile, between the first two, but the ?head? of the pile was pointing in the opposite direction of the JACOB/OWL rock. It is VERY confusing. My question is, am I just getting lucky finding these clues, or could there be more than one cache site here?
