Gillespie Dam Petroglyphs (Labyrinth) is a labyrinth installation in Gila Bend area, Arizona, United States. The design is a classical 7circuit layout with 7 circuits, 8 walls, built of rock carving. Documented age: Unknown (pre-contact) (Pre-1500 AD). Current condition: intact. Labyrinth petroglyphs carved on volcanic basalt bluffs overlooking the Gila River at Gillespie Dam in southern Arizona. The Gila River corridor served as a major trade and migration route for Ancestral Sonoran peoples, connecting the Pacific coast to interior desert communities. The labyrinth pattern occurs nowhere in nature; every documented instance traces back to a human hand. The labyrinth is one of several hundred sites of this type catalogued globally; each preserves the same unicursal walking-pattern with regional variation in scale, material, and date.
The labyrinth tradition spans at least 4,000 years of documented practice across northern Europe, the Mediterranean, the British Isles, North America, and the Indian subcontinent.
