About this map

Desert Peak stands as the primary landmark in this arid stretch of Pinal County, overlooking a landscape defined by ephemeral drainage systems and resource extraction. The eastern edge of the map is dominated by the Owl Head Buttes and the northern slopes of the Tortolita Mountains, where the rugged topography is marked by several mineral explorations. Evidence of late 20th-century mining activity is visible near these peaks, including a Mine Shaft, an Adit Mine Shaft, and various prospects.

The desert floor is carved by Guild Wash, Parker Wash, and Derrio Canyon, illustrating the natural water runoff patterns of the region. Infrastructure in the area is sparse, consisting largely of 4wd tracks, a southern Pipeline, and multiple high-voltage transmission lines that cut across the open basin. The boundary between Pinal and Pima Counties is delineated in the south, marking a transition in jurisdictional oversight during this period of the late 1980s.
