Original roofing timbers remain in portions of Lower Ruin.

23 PARTIAL ROOF. This large room contains a good example of Salado roofing technique. Walls of stone and mud were built in courses about 2 feet high each, until they reached 6 feet in height. A central upright post was then placed to hold a main roof beam. The smaller roof poles rested on the main beam, and above them went a layer of reeds, saguaro ribs, grass or other small poles. On top of these layers went a thick mud coat, deep enough to allow a shallow firepit to be safely built in the upstairs floor.

Hallway with partial mud-capped roof.

24 HALLWAY. The village was not built all at once. Construction at different times is revealed in sealed doorways, wall abutments, and hallways. This passageway gave access to three rows of ground floor rooms; it probably also served as additional storage space.

Interior roofing and hatchway to room above.

Stone-lined hatchway.

25 ORIGINAL ROOM. Look inside and imagine how dark and stuffy these rooms were. Often ground-floor rooms in the back of the cave—dark and poorly ventilated—were used just for storage. Ladders gave access to different floor levels in the village, sometimes through corner hatchways like the one in this room.
