ANCIENT ASTRONAUTS: This ancient petroglyph is thousands of years old. Are we witnessing ancient astronauts, or shamans dressed in ceremonial costume?! The photograph was taken at Utah's Nine Mile Canyon, which is actually 40 miles long and contains over 1000 petroglyphs created by various ancient cultures, including Anasazi, Fremont & Ute cultures. Nine Mile Canyon is often referred to as the world's longest art gallery! This particular petroglyph was made by the Fremont Culture somewhere between 500-1300 AD.
