Final answer:
The Ancestral Puebloans, also known as the Anasazi, are credited with building the cliff dwellings like Pueblo Bonito in Chaco Canyon, New Mexico. Their architecture featured large, multi-storied structures and kivas, which were ceremonial centers.
Step-by-step explanation:
The ancient North American culture responsible for the spectacular multistory cliff dwellings like Pueblo Bonito in Chaco Canyon, New Mexico, is known as the Ancestral Puebloans (formerly referred to as the Anasazi). These people constructed impressive settlements throughout the southwestern United States, particularly in areas such as modern-day Colorado, Utah, Arizona, and New Mexico around 700-1300 CE.
Among their most remarkable feats were the large multi-storied buildings, with Pueblo Bonito being the most studied and discussed, known for having up to 650 rooms and numerous kivas, which served as ceremonial centers.
