1986 Map of Eagle Mountains

About this map

The Eagle Mountain Railroad defines the industrial footprint of this desert landscape, stretching toward the massive Eagle Mountain Mine complex. This mid-1980s data highlights a region centered on resource extraction and conservation, with the industrial activity of the Eagle Mountains buffered by the expansive Joshua Tree National Monument. The settlement pattern follows the Interstate 10 corridor through Chuckwalla Valley, connecting outposts like Desert Center, Chiriaco Summit, and the lakeside station at Hayfield. To the south, the map captures the northern reach of the Salton Sea near North Shore and Desert Beach. This era is particularly notable for the high density of remote mining operations, including the Iron Chief Mine, Black Eagle Mine, and Red Cloud Mine, which are scattered throughout the Chuckwalla Mountains and Orocopia Mountains.
