The Park of Four Waters tour will take you through undeveloped, natural desert to the ruins of two Hohokam canal segments. “Hohokam” is an archaeological term for an ancestral Native American culture who built a highly sophisticated irrigation canal network in Arizona roughly between A.D. 450 and 1450. In order to support many large villages and small settlements, the Hohokam irrigated tens of thousands of acres along the Salt River to grow corn, beans, squash and cotton. This is a first come, first serve tour. Space is limited; sign up at the front desk.
