This culture was distinct from modern Pueblo cultures in many respects, and in particular, was found in many ares where it no longer persists.
For a long period, this culture was known as the "Anasazi" culture, as noted in the Wikipedia article. This name was given them by the Navaho -- and means "ancient enemies." It was altered because the Puebloans did not like "Anasazi," but called "Ancestral" to mark out the differences.
