1922 Map of Signal Peak

USGS Topo · Published 1959

About this map

The Southern Pacific Railroad cuts a diagonal path through this arid Pinal County landscape, anchoring early 20th-century settlements like Casa Grande, Arizola, and Toltec. To the north, the Gila River Indian Reservation encompasses the Sacaton Mountains, where Signal Peak and Black Butte rise above the desert floor. This 1922 survey documents an era of burgeoning agricultural infrastructure, notably the Casa Grande Florence Canal designed to divert water across the plains.
