Four beams at the center of the dwelling supported the roof of the house, upon which rafters were laid, connecting the top of the yurt to the earthen walls. Atop the wooden rafters, approximately a foot of straw was laid, on top of which the excavated dirt was placed and stamped down. An opening atop the yurt, off to one side of the four posts and supported by the two beams, served as a smoke hole and an entrance.
