Ancestral Pueblo culture, also called Anasazi, prehistoric Native American civilization that existed from approximately ad 100 to 1600, centring generally on the area where the boundaries of what are now the U.S. states of Arizona, New Mexico, Colorado, and Utah intersect.

When did the Anasazi disappear?

In the late 1200s, the Ancestral Puebloan people of what is today the Four Corners Region of the U.S. Southwest suddenly vanished. For centuries, the culture—also known as the Anasazi—had grown maize and built elaborate villages and sandstone castles. Then, it was gone.

Do the Anasazi still exist?

The Anasazi, or ancient ones, who once inhabited southwest Colorado and west-central New Mexico did not mysteriously disappear, said University of Denver professor Dean Saitta at Tuesday's Fort Morgan Museum Brown Bag lunch program. The Anasazi, Saitta said, live today as the Rio Grande Pueblo, Hopi and Zuni Indians.
