1940 Map of Hillsboro

About this map

Hillsboro and Kingston serve as the primary hubs in this high-desert mining landscape, where the rugged terrain of the Gila National Forest meets the scattered ranching operations of Sierra County. The 1930s survey data reveals a territory defined by hard-rock extraction and isolated homesteads, with the Gray Eagle Mine and Silvertail Mine marking the era's industrial activity. Dozens of deep canyons, such as Percha Creek and Tierra Blanca Creek, carve through the landscape, providing essential water sources for cattle operations like the JP Nunn Ranch and the O Bar O. Notable landmarks such as Schoolhouse Mtn and Empire Peak rise above the gulches, while the presence of the Kingston Ranger Sta indicates the early administrative management of the forest's timber and grazing resources.
