Located ten miles south of Santa Fe, it was the site of the largest prehistoric mining activity on the continent because the huge turquoise deposit was partially exposed at the surface. Miners from the San Marcos Pueblo, who later moved to Santo Domingo Pueblo south of Santa Fe, most heavily worked the mine. Using only stone axes, mauls, antler picks, and chisels, Pueblo miners removed 100,000 tons of solid rock to create a pit mine 200 feet deep. They dug other vertical shafts into the ground to reach veins of turquoise. Miners carried tools and leather rock buckets on their backs as they climbed in and out of the shafts using notched logs as ladders. The turquoise obtained from this hard work traded among early peoples from Mexico to the Midwest and from the east to west coasts. In New Mexico, many pieces of Cerrillos turquoise for personal and trade use have been unearthed in the prehistoric ruins of Pueblo Bonito in Chaco Canyon. The Pueblo peoples continued to extract turquoise from the Cerrillos mine until the 1870's when a silver mining boom raised interest in the area. The Tiffany Company in New York and its associates bought up the mine area and extracted $2,000,000 worth of turquoise between 1892 and 1899.
