The inside of a Hopewell Culture house may have looked something like this, a place for storage and for shelter from the cold. The houses were based on poles pounded into the ground, usually in a rectangle shape with rounded corners. Twigs were woven in and out of the poles and then the whole plastered with mud and clay to form walls. Roofs were thatched. The people may also have used reed mats to cover walls and roofs at times. At the Stubbs Earthworks, patterns left from poles show buildings of a wide veriety of shapes.
