One of the best producers of copper in Northern Arizona was the Grand Gulch Mine, located on the edge of the Grand Wash Cliffs in the western part of the Arizona Strip.
This remote desert region north of the Grand Canyon, while within Arizona, has historically served as an extension of Mormon settlement in southern Utah.
The article "Mine Tales: Grand Gulch Mine was major copper producer, opens a new window" describes how a member of the Shivwits band of Paiute Indians told Samuel L. Adams, Joe Cunningham and Richard Bentley about a vein of rich copper ore running as high as fifty percent. The article details their exploration of the area and what they extracted, and follows the history of Grand Gulch Mine ownership.
