About this map

The mining settlements of Hillsboro and Kingston anchor this mid-1930s landscape in Sierra County, New Mexico. Situated along Percha Creek, these towns supported a network of hard-rock operations including the Gray Eagle Mine and Silvertail Mine, alongside prospecting sites like Sawpit. The topographic detail reveals a transitioning economy where ranching began to define the open land between the peaks, evidenced by family-named holdings such as the Mackey Ranch, E Nunn Ranch, and JP Nunn Ranch.

Deep canyons and high-elevation landmarks dominate the western edge, including Seven Brothers Mtn and the Kingston Ranger Sta. Notable geological features like The Box on Percha Creek and the remote Golddust Camp further east reflect the era's mining-to-ranching footprint. From Schoolhouse Mtn to Animas Peak, the survey provides a clear view of the complex drainages and passes, such as Sibley Gap, that defined travel through the Black Range foothills.
