Blackwater stands as a central community within this desert landscape, situated near the braided channels of the Gila River and its accompanying Little Gila River. The local infrastructure is deeply tied to the management of water and agricultural land, evidenced by the Blackwater Lateral and the N Side Canal that cut through the Pinal County terrain. The survey captures a transition between the established settlements of Coolidge and Florence, while the southern edge of the map features the northern boundary of the Casa Grande Ruins National Monument. Notable landmarks like Mineral Butte, Twin Buttes, and Walker Butte provide topographic relief against the grid of roads such as Presbyterian Church Rd and Blackwater School Rd. This 2018 record shows how modern development and irrigation networks continue to follow the ancient path of the Gila.
