About this map

Mining operations dominate the landscape around Mammoth and Tiger as shown in this mid-century survey with later updates. The heavy industrial footprint of the San Manuel Copper Mine and its Power House are central to the area, supported by a network of Conveyors, a Tailings Pond, and the massive Smelter facility located further south. This industrial activity is contrasted by the dry desert landscape carved by numerous drainage systems, including Tucson Wash, Mammoth Wash, and Cottonwood Wash, all feeding into the San Pedro River valley.

Evidence of the region's diverse history is scattered across the Black Hills, from the Pearl Mine and Tar Mine in the northwest to the Golf Course and Drive-in Theater near the river. Genealogical interest is found in the local Cemeteries on the edge of Mammoth, while landmarks like Signal Peak and Red Hill provide orientation across the complex terrain. The map also records early water sources like Shultz Spr and McKinney Dam Spring, which were vital for life in this arid corner of Pinal County.
