1951 Map of Quail Mountains

About this map

Epsom Salts Works stands as a lonely industrial landmark in this arid landscape, connected to the northwest by the Monorail Abandoned. This unusual piece of desert infrastructure hints at early 20th-century efforts to extract minerals from the remote basins between the Owlshead Mountains and the Granite Mountains. The 1948 aerial survey captures a transitional moment as the area became increasingly defined by federal defense needs, evidenced by the Camp Irwin Military Reservation Boundary and the Naval Reservation Boundary.
