About this map

The San Pedro River valley in Pinal County serves as the central artery for this late-1940s landscape, where ranching and resource extraction converge. The eponymous Clark Ranch and nearby Clark School anchor the local community, while industrial activity is evidenced by a Smelter located near Cottonwood Wash. The terrain is defined by complex drainage systems and hydrothermal activity, including an Artesian Well (Hot) and an Artesian Well (Warm) along the river's eastern bank.

Erosion and elevation shifts are visible across Bunker Hill and the numerous watercourses feeding into the main valley, such as Copper Creek, Scanlon Wash, and Gust Wash. The reliance on local water sources is emphasized by several Windmill sites and named springs like Copper Spring, illustrating the infrastructure required to sustain life and industry in this arid environment before modern development expanded through the region.
