Ancestral Puebloans

The Ancestral Puebloans were an ancient Native American civilization. They lived in what is today the southwestern United States. Their settlements were in what are now Colorado, Utah, Arizona and New Mexico. They were called the Anasazi by the Navajos.
Their culture ceased in the 15th century AD. The civilization left remains of some large and important places. Two of these have been classified as UNESCO World Heritage Sites. Remains found by archaeologists show knowledge of pottery, weaving and irrigation. They also drew symbols.
