The Hieroglyphics were found cut into the salt marshes of New Jersey. I immediately thought it must be a hoax but I looked google earth and sure enough there they are!

To find it on Google Earth just search for "Taylor lane manahawkin" and follow Taylor lane to the right and you will find it.

From article:

So what is 'proof'? We have to remember that on the ground these are nothing but a series of open water wet spots in a marsh, and appear to have no meaning. But from the air they make a pattern of an unmistakable message. Surely salt marshes are alive and growing, and the width of these lines narrows as plants expand; but even with what is left, this is a spectacular site. Also, rising sea levels may have overtaken and obscured many sections of the 'message' but THIS IS NOT NATURAL.
