Anasazi accommodation

People here took advantage of the benefits of building stone structures against south facing walls. Most of caves has small masonry buildings, known as talus pueblos, constructed in front of them. The thick stone wall exposed to the direct rays of the sun capture and radiate heat in the winter, keeping the buildings and cavates much warmer that the air outside. In the summer the wall insulate the stone rooms, keeping them somewhat cooler that the air outside.
