Yuma County holds 12 documented ghost towns, including Aztec, Castle Dome Landing, Colorado City — Castle Dome keeps them company on the map.

The story of Castle Dome

Arizona's ghost towns are sun-bleached and honest — copper, silver, and gold camps that lived fast and died the moment the ore did.

The Castle Dome Mountains (Tolkepaya Yavapai: Wi:hopuʼ) are a mountain range in Yuma County, Arizona, within the Kofa National Wildlife Refuge. Castle Dome Peak, the high point of the range, is a prominent butte and distinctive landmark. The peak is 3,780 feet (1,152 m) high, and is located at 33°05′04″N 114°08′36″W. Castle Dome was named by American soldiers at old Fort Yuma in the 1880s. Early Spanish explorers called the same peak Cabeza de Gigante, "Giant's Head."
