Location, Culture, and Transportation
The Superior mining area is in northeastern Pinal County, Arizona (Fig. 1). The area was officially organized as the Pioneer mining district but is better known as the Superior mining area.
Superior, the principal settlement within the area, in 1940 had a population of about 5,000, depending principally upon operations of the Magma Copper Company. The old town of Silver King, now largely deserted, was at the Silver King mine, in the northern part of the area shown on Plate I.
