Chaco Canyon is located in the Chaco Culture National Historical Park in New Mexico, USA.
The Chaco Culture National Historical Park is a National Historical Park managed by the National Park Service of USA. It hosts the densest and most exceptional concentration of pueblos (i.e. old and modern communities of native Americans) in the American Southwest. The park has been inscribed into the UNESCO (United Nations Educational, Scientific and Cultural Organization) World Heritage List in 1987.
“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.” – UNESCO
