There's a petroglyph of a Viking ship in the cliffs above the Agua Fria River north of Phoenix also. I have no explanation of it or of the "space men" petroglyphs a couple miles south of it but in the same canyon. I can give general directions to anyone who asks by PM but getting permission to cross the private ranch to get to them is up to you. The ranch manger who I used to know died a few years ago in a helicopter crash.
