Located in in southwestern Colorado, Mesa Verde is home to the famous cliff dwellings of the ancient Anasazi people. It is one of the most significant archeological preserve of Native American culture in the US. In the 12th century, the Anasazi start building houses in shallow caves and under rock overhangs along the canyon walls. The most famous of these is Cliff Palace. The Ancient Puebloans constructed it from sandstone bricks, and mortar made from ash, clay and water. It encompassed 150 rooms and 76 open areas. Climatic change and increased population placed the communities under stress and by the late 1270s, the Ancestral Puebloan population began migrating to what is now New Mexico and Arizona.
