A ghost town is defined as a town or city that has been abandoned due to a natural or human made disaster or loss of economic viability or population to sustain a post office. In the western United States there are many mining boom towns that were abandoned after the mines or smelters closed down. There are a number of ghost towns along the Copper Corridor area. Many of them were once promising mining camps whose population left when the ore bodies played out. Some of these ghost towns were in the Oracle area: American Flag 1880 – 1890 & Manlyville 1881 – 1888.
In the Mammoth and Dudleyville areas there was Camp Grant 1875 – 1879, Schultz 1894 – 1902, Tiger 1939 – 1954, Copper Creek 1906 – 1942, Alma 1891 – 1898, Mesaville 1878 – 1888, Sombrero Butte 1919 – 1945.
