About this map

The Casa Grande National Monument anchors the northeastern corner of this desert landscape, where the ancient history of the Gila Valley meets the agricultural and industrial expansion of the early 1920s. Centered on the Sacaton Mountains, the map reveals a critical infrastructure network defined by the Casa Grande Florence Canal and the Southern Pacific railroad. These features support a string of early settlements, including Arizola, Toltec, and Eloy, which appear alongside rural educational sites like Selma School and Pinal School.
