What could the prehistoric artists of North America have in common with the graffiti artists of today? Picked into the rocks of southwestern Arizona, a couple hour drive from Tucson, are marks of the Patayan and Hohokam traditions. The petroglyphs are an insight into these civilisations, their religions and their lives.

Aaron Wright is a Preservation Archaeologist whose research is currently focused on the Hohokam and Patayan traditions. He joined Don to explore what this rock art has in common with sites across North America, and what makes it different.
