Mesa Verde National Park
The park occupies 81.4 square miles (211 square kilometers) near the Four Corners and features ruins of homes and villages built by the ancestral Puebloan people, sometimes called the Anasazi.  The ancestral Puebloans made these stone villages their home in the 13th century. However, the first ancestral Puebloans had settled in Mesa Verde over 600 years before the cliff dwellings were ever built.
