Castle Dome City
Castle Dome City, AZ - Ghost Town - Castle Dome Mining Camp - Though prospecting and planning commenced years earlier, modern mining in the area didn't begin in earnest until 1869 due to hostilities with Native Americans. When the mines finally did begin operations, the mining camp that sprung up was known as Pitoti after a weed thought to be found only in that area. As the area grew, the town was renamed Castle Dome, and a post office was established in that name on December 17, 1875. Less than a year later, however, the post office was discontinued on December 4, 1876.
As with many mining boomtowns, mining activity diminished, and the Castle Dome Landing post office closed down on June 16, 1884. The mines reopened in 1890, and the area became a significant source of lead for both World War I and World War II. In particular, when the Arizona Lead Company reopened the mines in 1943, they were able to produce significant amounts of lead in order to meet wartime demands.
After World War II, the demand for lead decreased, and the town again went into decline, though mining activity continued for some years in the area. The school was shut down in 1950, and the mines went into and out of use as the price of silver, still found in the area, rose and fell. By 1978, the mines were all shut down, and the last of the residents were gone. [Wiki]
