Most of the residents lived in circular or rectangular houses which they built between the river and the eastern secondary wall. The placement of the structures suggests that the layout was planned. The dwellings were built around a central ceremonial plaza likely used for rituals and public gatherings, as has been found at similar locations. Posts for the house frames were placed either in individual holes, or in a trench dug slightly narrower than the posts. The walls were completed with wattle and daub, a plaster mixture of grass and clay. The roof was covered with bark or thatch. The doorway usually faced south to keep out the winter's north winds. Inside, a single family slept on pole-frame beds, covered with tamarack boughs, deer skins, and furs. Sometimes a fire was kept in the middle of the house and a hole in the roof let out the smoke. Storage pits dug in the earthen floor of the house held foods such as corn, nuts, and seeds in woven bags. Perishable foods such as meat were most likely stored outside prior to cooking. Refuse pits for garbage and community storage pits were located outside.
