About this map

San Manuel emerges as a focal point of development in this desert landscape, with 1972 revisions captured in purple to show the expansion of the urban area. The terrain is defined by a series of drainage systems including Peppersauce Wash, Big Wash, and Catalina Wash, which all flow toward the San Pedro River in the east. This 1948 survey, updated decades later, illustrates the transition from a traditional ranching and mining environment to a more structured settlement.

Resource extraction and water access are central to the area's geography, highlighted by the Black Hills Mine situated within the Black Hills. Remote outposts like Sacaton Ranch and infrastructure such as the Artesian Well (Hot) near the northern boundary point to the essential challenges of the Pinal County arid corridor. The map also records the boundary line between Pinal County and Pima County, providing a clear record of local administrative divisions and land use.
