14. Room construction.
Upon entering this room one can see how the original builders took advantage of two natural rock walls. This eliminated construction of two sides of the room. The lower portion was filled 5 feet (1.5m) deep with trash before the first floor was laid.
Original timbers are still in place above the opening in the rear wall. Holes for beams that supported the second story are visible in the side walls. A considerable number of beams was recovered during the excavations at Wupatki, and the study of this material has contributed greatly to the tree-ring method of dating in the Southwestern region.
Most of these beams were of ponderosa pine, not present nearby. It is possible the pine forest was closer to Wupatki then than now.
