About this map

The Picacho Mountains and Granite Hills dominate this arid landscape in central Arizona, where mining activity and ranching intersect with seasonal watercourses. Prospecting is evident along the northwestern slopes, anchored by the North Star Mine and other unnamed mines accessed by rugged 4wd trails. These desert elevations give way to broad alluvial plains etched by drainage systems like Brady Wash and the curiously named Tom Mix Wash.

Human presence is sparse but strategic, focused around water management and transport. Features such as Deep Well Ranch and various watering points like Heifer Pasture Tank, Pedia Tank, and Repecita Tank highlight the infrastructure required for cattle operations in a dry climate. The presence of a Landing Strip and the emergence of Iron Valley Rd suggest the early stages of mid-century infrastructure expansion within the valley, while much of the terrain remains accessible only by primitive routes.
