 The area that was to become Tiger was first settled in 1881 after Frank Schultz located gold ore in what was to become the Mammoth Mine.The camp that settled around the mine took the name Schultz, and a post office was established under that name on July 12, 1894.Since water, needed for refinement of ore, was not present near the mine, a mill was established away on the west bank of the San Pedro River, in a town that came to be known as Mammoth, after the mine and the mill.
