That’s a part of Cliff Palace, one of the large cliff dwellings at Mesa Verde National Park.
Did you answer the question about who lived here with Anasazi? That’s what most people with some familiarity reply. But that term isn’t accurate; indeed, it is offensive to some. More correctly (politically and otherwise) the people who lived in the cliff dwellings of Mesa Verde and throughout the four corners area from 1100 to 700 years ago are called the Ancestral Puebloans. Their descendants are the Pueblo Indians of modern New Mexico and Arizona.
Anasazi derives from the Navajo words for ancient and enemy. The term was first applied to the cliff dwellings and other deserted settlements by Richard Wetherill, a rancher who was among the first Anglos to explore the area. It was adapted by archaeologists in the 1920s and came into popular usage in part as a result of ranger-led tours and National Park Service literature. In the past decade Ancestral Puebloans has become the generally preferred term.
