CONSTRUCTION

Method and Sequence

(1) A pit was excavated into prehistoric ground surface to an unknown depth (level of prehistoric ground surface is unknown in this area), but the pit was excavated into decomposing Dewey Bridge sandstone at least 18 cm (see stratigraphic profile); (2) typical kiva construction would have been to then build the masonry bench face inside excavated kiva pit; (3) construction fill would have been added between the bench face and the wall of the pit up to the top of the bench face; (4) pilasters would have been constructed on the bench surfaces; (5) roof would have rested on pilaster(s).
