About this map

The Mimbres River valley defines the western edge of this landscape, supporting the established settlements of San Lorenzo and San Juan. To the east, the terrain rises sharply into the high elevations of the Black Range, where the dense network of canyons and peaks reflects a history of both natural preservation and industrial extraction. Within the Gila National Forest, the map identifies several significant workings, including the Royal John Mine, Columbia Mine, and Rose Mine, indicating the mineral importance of the area during the mid-20th century.

Transportation through this high-altitude environment is marked by early routes like the Railroad Canyon Trail and the Gila River Trail, while the highway crossing at Emory Pass provides the primary passage across the continental divide. The placement of named water sources such as Noonday Springs and Cold Springs underscores the importance of reliable water in this part of New Mexico, serving both the mining camps and the valley communities.
