|Artist's reconstruction of a large house based on archeological remains uncovered at House Mound #5 at Spiro. The grass-thatched roof is supported by four interior posts. The walls are made of closely spaced thin poles set within a foundation trench. Daub (dried mud) plaster sealed the walls. The extended entranceway helped keep heat from escaping in the winter. This very large house (9-x-9 meters or 29-x-29 feet) is thought to have been an elite residence, rather than an ordinary dwelling. Courtesy Oklahoma Archaeological Society.
