About this map

The Galiuro Mountains and the high desert canyons of the Coronado National Forest dominate this early 1970s survey. This rugged landscape is defined by the ephemeral Cienega Wash and the San Pedro River, which anchors the southwestern corner of the quadrangle. Cattle ranching and mineral exploration are evidenced by the scattered infrastructure across the terrain, including the YLE Ranch and the 16 to 1 Mine situated near Kielberg Canyon.

Survival in this arid environment relied on a series of managed water points such as YLE Tank, Peters Well, and Border Well. These features, along with various Jeep Trails, trace the movement of people through deep incisions like Cement Dam Canyon and Rhodes Canyon. The map also documents the triple-point junction of Graham, Pinal, and Pima counties, a significant geographic marker for local historical research.
