Historical Significance:
This native copper plate was erected by the State of Arizona in conjunction with Maricopa Chapter, NSDAR, as the Poston Butte pyramid was completed, twenty‑three years after Poston’s death. The copper was provided by New Cornelia Copper Company with General John C. Greenway acting as General Manager. Arizona Governor George W. P. Hunt and George H. Kelly, State Historian, attended the dedication. The copper plaque was mounted to the side of the pyramid.
Because of vandalism, the plaque was removed from the monument by the Pinal County Historical Society in 1925 and placed in the society’s museum.
