Structure Use

Structure 405 is similar to other pit structures occupied during the late Pueblo III period and was probably used in a combination of domestic and ritual activities. The presence of multiple bowl and jar sherds on the structure floor, as well as a two-hand mano fragment indicates a domestic use of the structure. The presence of a hearth (Feature 2) also indicates a domestic use of the structure and would have been used for light, heat, and food preparation. The presence of a sipapu (Feature 1) indicates a ritual use of the structure.


Structure 405 was abandoned during the late Pueblo III period. Vessels and tools were left on the floor surface. The structure was intentionally burned. The roof sediments collapsed on to the floor surface.


Natural sediments accumulated above the collapsed roof. Structures 401 and 407 were constructed on the natural fill. Additional natural sediments accumulated above Structures 401 and 407; the upper portions were disturbed by plowing.
