One of the most notable achievements of the ancestral Puebloans was the construction of elaborate stone and adobe structures, specifically cliff dwellings and pueblos, which were built into the cliffs or on the mesas of the southwestern United States. These structures demonstrate the engineering skills, architectural knowledge, and advanced building techniques of the ancestral Puebloans. Additionally, their mastery of agriculture allowed them to sustain large populations in challenging environments, contributing to their thriving and prosperous society.
