1922 Map of Signal Peak

About this map

The Gila River Indian Reservation occupies the northern reaches of this Pinal County landscape, where the Sacaton Mountains rise sharply above the desert floor. The survey highlights early 20th-century water management efforts, specifically the Casa Grande Florence Canal, which cuts across the central plains toward established railroad settlements. Along the Southern Pacific tracks, the towns of Arizola, Toltec, and Eloy serve as vital hubs for the local agricultural and mining economy, including the remote American Boy Mine tucked near the Casa Grande Mountains. This era of development is further evidenced by several rural schoolhouses, such as Selma School and Pinal School, which provided community anchors for families settled near the North Branch Santa Cruz Wash and Mc Clellan Wash.
