About this map

The Gila River Indian Reservation dominates the northern reaches of this Pinal County landscape, where the jagged rises of the Sacaton Mountains and landmarks like Signal Peak and Black Butte break the desert floor. In the south, the Southern Pacific Railroad cuts a straight diagonal through the terrain, anchoring the development of early rail-side communities including Arizola, Toltec, and Eloy. The irrigation of the arid flats is documented through the path of the Casa Grande Florence Canal, a vital artery for the region's agricultural growth.
