This large boulder, covered in petroglyphs, is easily accessible from the Pima Canyon Entrance to South Mountain Park. It can be found by parking at the end of East Pima Canyon road and taking the Desert Classic Trail south for a couple hundred feet.
The boulder has a wide variety of geometric and anthropomorphic shapes competing for space. In the center, a vertical, three-tiered structure points to a spiral pattern at the very top.
