In page Pueblo III Period:

"

During the Pueblo III Period most people lived in communities with large multi-storied dwellings. Some moved into community centers at pueblos canyon heads, such as Sand Canyon and Goodman Point pueblos in the Montezuma Valley; others moved into cliff dwellings on canyon shelves such as Mesa Verde or Keet Seel in the Navajo National Monument. Typical villages had included kivas, towers, and dwellings made with triple-coursed (three rows of stones) stone masonry walls.[1][2][3][4] T-shaped windows and doors emerged for both surface and cliff dwellings.[5]
