The petroglyphs on the rock outcrop shown here are an excellent example of rock art left by the Hohokam Indians, believed to have dwelt in the Valley of the Sun between 700 and 1450 A.D..
Most of the rock art on Hayden Butte Preserve is located on the south slope adjacent to the Arizona State University Sun Devils Stadium.
Sadly, many of these ancient works have been damaged by vandalism. As a result, signs now prevent the public from getting closer than about 100 feet away. I took the pics below with a telephoto lens and tripod to give you an up-close view.
What’s the difference between a petroglyph and heiroglyph?
A petroglyph is traditionally a “one-off” design etched into a rock face. A hieroglyph is a series of petroglyphs arranged (presumably) to tell a story or share a message.
Both were left by ancient people. Common symbols include game (deer or bighorn sheep) or geometric patterns ranging from interconnected spirals to squiggles.

After publishing the original post, I received messages from readers to expand our understanding of rock art.
Adam offered this explanation: Hieroglyphs are an alphabet. Petroglyphs are both scratched and etched.
Petroglyphs are drawings or designs that are carved or scratched into the rock.
Reader Tom offered this insight: Pictographs are drawings or designs that are painted on the rock. We have both of these in Arizona and the southwest.
Most pictographs are found in caves or under overhangs.
Since they are made of “paint” they have been washed away over the years by rain.

Paul, Nice article and great photos of the petroglyphs. Good job.
In your description you night include : Petroglyphs are drawings or designs that are CARVED or SCRATCHED into the rock. Pictographs are drawings or designs that are PAINTED on the rock. We have both of these in Arizona and the southwest. Most pictographs are found in caves or under overhangs. Since they are made of “paint” they have been washed away over the years by rain.
Sincerely, Tom K, petroglyph enthusiast.

Thank you. I’ll update the post. I learned that after publishing this post and failed to update it.
It’s a common mistake. You’re in good company.
