Ancient Pueblo Peoples

Ancient Pueblo peoples or Ancestral Pueblo peoples were an ancient Native American culture centered on the present-day Four Corners area of the United States, comprising southern Utah, northeastern Arizona, northern New Mexico, and southwestern Colorado. They lived in a range of structures, including pit houses, pueblos, and cliff dwellings designed so that they could lift entry ladders during enemy attacks, which provided security. Archaeologists referred to one of these cultural groups as the Anasazi, although the term is not preferred by contemporary Pueblo peoples.^[2]
