The San Pedro River corridor near the Pinal and Pima county line defines this arid landscape in southeastern Arizona. This 2021 survey illustrates a complex network of seasonal drainage systems, including Peppersauce Wash, Stratton Wash, and Alder Wash, which carve through the high desert terrain. The topography is anchored by the Little Black Hills and the deep incision of YLE Canyon, reflecting the intricate geological features of the San Pedro Valley. Local transit and land access are indicated by numerous named tracks and ranch roads, such as Black Hills Mine Rd and Campo Bonito Rd. These routes connect remote areas like the 3C Ranch Rd to larger thoroughfares, highlighting the region's historical and contemporary reliance on ranching and mining infrastructure.
