The primary dwellings of this period were round or circular
pit-houses that were built on open land and partially below the ground surface. The entrance to the house faced east or south. Logs and rocks were often used for the dwellings foundation. The building materials for the walls could include stacked logs,
jacal or poles and brush. In the center of the dwelling was a
fire pit. Some early people built their dwellings within the natural protection of
rock shelters, especially during the beginning of this period. ==Agriculture==
