These petroglyphs at Signal Hill in Saguaro National Park were created by the Hohokam people, whose communities flourished across southern Arizona between about A.D. 450 and 1450. Archaeologists believe many of the carvings seen here were created roughly 550 to 1,550 years ago, though their exact meanings remain unknown.
Spirals, human figures, animals, and abstract symbols cover the dark volcanic basalt, offering a remarkable connection to the people who traveled and lived in the Sonoran Desert long before modern Tucson existed.
It's one of those places where the landscape isn't just beautiful—it's part of a story that's been preserved for more than a millennium.
