1970 Map of Boundary Cone

Industrial infrastructure is etched into the desert floor via a network of jeep trails and a prominent pipeline cutting across the northwest corner. From the high elevations of Wrigley Peak down to McHeffy Butte, the map provides a look at the complex geography of the Oatman mining district. Local history researchers can pinpoint numerous smaller operations like the Alcyone Mine, Black Range Mine, and Cook Mine that characterize the era's mineral exploitation.
