“Construction of original Ancestral Puebloan dwellings Materials: The original dwellings were built from local sandstone, with a mortar made of local soil, water, and ash. Labor: Workers shaped sandstone blocks with harder stones and used wooden beams for floors and roofs. Design: They were built into natural rock overhangs, with rooms often stacked and tucked into the cliff face for both shelter and temperature regulation.” | Josie Plachta
