Duquesne, Arizona

Duquesne is a ghost town in the Patagonia Mountains in eastern Santa Cruz County, Arizona, near the international border with Sonora, Mexico. The town, which is currently under private ownership and closed to the public although the roads are almost all public, was once the headquarters of the Duquesne Mining and Reduction Company and is the site of the Bonanza Mine. Washington Camp is approximately one mile northwest of Duquesne and was where the mine's reduction plant was located.
