Turquoise Mining Communities of New Mexico’s Cerrillos Hills: A Legacy of Ancient Trade and Modern Discovery

The Cerrillos Hills of New Mexico hold one of North America’s most significant
concentrations of prehistoric and historic turquoise mining sites. Archaeological
evidence indicates that indigenous peoples began extracting the precious blue-green
stone from these hills as early as 900 CE.

This region’s rich mining heritage spans over a millennium, encompassing Native
American, Spanish colonial, and American mining operations that have shaped the
cultural landscape we see today.

This massive mining complex dominates the Cerrillos landscape with its impressive
crater, approximately 130 feet deep and 200 feet wide, created through centuries of
indigenous mining activity. Archaeological excavations in the 1960s uncovered stone
hammers, antler picks, and other mining tools dating back to the Ancestral Puebloan
period, along with evidence of sophisticated water management systems and tool
maintenance areas.

Recent geological surveys have identified at least twelve distinct mining episodes between 900 and 1400 CE, demonstrating the site’s importance for pre-Columbian societies.

Historical records from Spanish colonial archives document the Santo Domingo
Pueblo’s deep connection to Cerrillos turquoise mines, revealing a complex system
of traditional mining rights and cultural practices. Archaeological evidence shows
continuous mining activity by the Santo Domingo people from the 12th century
through the Spanish colonial period, with distinctive tool marks and extraction
techniques.

The pueblo’s traditional mining rights were later recognized in U.S. territorial documents from the 1800s, though this recognition came after significant political struggle and legal battles.
