Cerro Colorado is a ghost town in southern Pima County, Arizona. The town is located off Arivaca Road, near Arivaca, and is best known for the massacre of mining employees by Mexican outlaws and buried treasure.
Cerro Colorado was established around 1855 by Charles D. Poston, who owned the Sonora Exploring & Mining Company in Tubac, Arizona. The most prosperous mine in the area was the Heintzelman Mine, named after Major General Samuel P. Heintzelman, who was the first president of the mining company and later grew famous during the American Civil War. The post office was established on April 17, 1879, and closed on April 15, 1911.

In 1861, fifteen Mexican and Native American men were killed after being buried alive in their shaft when the roof caved in. The men were deep within the shaft so no rescue was possible or attempted, this frightened the Mexican employees who felt the mine was haunted so they left and went home to Sonora. Several German and American miners then became employed.
