There's a Navajo historian on YouTube who has some things to say about Chaco. According to their traditions, Chaco was not a good place, and the Anasazi were regarded as being completely different - and not in a good way - from the other people in that region.
The term “Anasazi” is a Navajo word = means “ancient enemy.”
The Apache and Navajo are from northwestern Canada and eastern Alaska.. Their Athabascan ancestors migrated south when the Spanish were moving north from new Spain / old Mexico..
Hopi call their ancestors: Hisatsinom
