The Mineral Park Mine, in the Cerbat Mountains 14 miles northwest of Kingman, was first mined by Indians centuries before white man came to the area. It is one of the three sites of prehistoric mining localities in the state of Arizona. Mineral Park was the most extensively worked area by the Indians of the three. S.A. "Chuck" Colbaugh found a cache of stone hammers uncovered in ancient trenches and tunnels, when he had the turquoise mining concession in May of 1962. Ithaca Peak and Turquoise Mine (formally called Aztec Mountain or Aztec Peak) are the most famous of the peaks in the area containing turquoise.
