South Mountain Park in Phoenix is home to thousands of petroglyphs left behind primarily by people of the Hohokam prehistoric culture. A petroglyph is a type of “rock art” formed by pecking away the outer weathered layer of stone to expose the lighter stone beneath, thereby creating images. They consist of representations of life forms such as animals, birds, or people; geometric designs; and shapes or lines that may have had symbolic purposes.
What we know about the ancient Hohokam people of the Phoenix area:
- Hohokam is a term that roughly translates to “those who have gone”
- They inhabited central and southern Arizona from approximately AD 450 to 1450
- They probably did not reside in the South Mountains
- Evidence suggests they hunted, gathered plants and other resources, tended gardens or fields, conducted ceremonies, and made journeys here
It’s likely the South Mountains were sacred to the ancient Hohokam as they are to local tribal communities today. Rock art patterns may symbolize Hohokam activities or mark places that were important to them.
This rock formation bearing dozens of ancient petroglyphs is about 100 yards south of the Pima Canyon Trailhead parking lot.
Rock art can be found along these trails in South Mountain Park:
- Desert Classic
- Hidden Valley
- Holbert Trail
- Judith Tunnel Trail (accessible)
- Kiwanis Trail
- Mormon Trail
- Pyramid Trail
- Telegraph Pass Trail

The Hohokam people also left behind artifacts such as stone tools and pottery in various canyons within South Mountain Park. Some of their artifacts are now on display at Pueblo Grande Museum.
Petroglyph etiquette
If you see petroglyphs, the best thing to do is take a picture from the trail. While it’s tempting, don’t touch them. The oils on our hands can damage the rock art. Staying on the trail is important for the wildlife habitat as well as for preserving the petroglyphs.
If you see pottery pieces or sharpened rock tools, they are the remnants of ancient Hohokam activities and should remain where you find them.
Help preserve these sites by following “leave no trace” principals. Take only photographs and leave only footprints.
Help keep Arizona beautiful: Leave no trace
Because the Hohokam people did not leave behind a written language, we are not certain of the meaning of the petroglyph symbols found on the rocks. That’s part of the thrill: pondering what they may have meant to the Hohokam or what a panel of symbols might mean to you.
About your guide
Since moving to Arizona in 2012, I’ve logged hundreds of miles on hiking trails and byways. After one particular hike to the falls of Havasupai in the Grand Canyon, I became obsessed with exploring the many natural wonders of Arizona.
Now I love sharing some of my most fascinating discoveries with others.
