Joe:
As always your opinions and points are well taken.As viewed on my monitor,your version appears to have darkened the images more than the surrounding markings.I might add that lighting plays a part in both the coloring and contrast of my original photo,as well as affecting any subsequent retouch.The area of the rock face that has the image is between two vertical breaks in the cliff,and is slightly cove-shaped.This would probably affect the colors in the frame as well.I think that the only way to determine whether or not this is "hand of man" will be to make the hike and the climb back.If it is some kind of "paint" and that paint was made from local material,then that should be evident.If it is just a natural feature,I will post the GPS co-ords so that all who are interested might make it a hike destination,and a lunch stop with a view.
As far as any belief that this is Aztec.I don't.But if it is real,and not natural,then it certainly would indicate that the history of the Superstitions as we know it,is incomplete.
I would not necessarily expect that the painting would match those on the codices,or even those on the walls of tombs/temples.After all,the canvas is not flat,or smooth and it's way up there.Probably wasn't even the same artist,or paint,maybe someone's first attempt at depicting the big guy.Might even be the first painting ever done of Quetzalcoatl.Don't mind me,I'm just musing again.
Janiece: the pic was taken in the first week of may 08.
