UNESCO Description of the World Heritage Site

For over 2,000 years, Pueblo peoples occupied a vast region of the south-western United States. Chaco Canyon, a major centre of ancestral Pueblo culture between 850 and 1250, was a focus for ceremonials, trade and political activity for the prehistoric Four Corners area. Chaco is remarkable for its monumental public and ceremonial buildings and its distinctive architecture – it has an ancient urban ceremonial centre that is unlike anything constructed before or since. In addition to the Chaco Culture National Historical Park, the World Heritage property includes the Aztec Ruins National Monument and several smaller Chaco sites managed by the Bureau of Land Management.

Encyclopedia Record: Chaco Culture National Historical Park

Chaco Culture National Historical Park is a United States National Historical Park in the American Southwest hosting a large concentration of pre-Columbian indigenous ruins of pueblos. The park is located in northwestern New Mexico, between Albuquerque and Farmington, in a remote canyon cut by the Chaco Wash. Containing the most sweeping collection of ancient ruins north of Mexico, the park preserves one of the most important cultural and historical areas in the United States.
