House No. 4 was the only occupational feature discovered at Mound D.
_House No. 4_
This house was circular in shape, with an exterior wall formed of
upright poles, wattle, and clay daub. Post molds indicated that there
were at least 27 of the upright poles in the exterior wall (Fig. 10).
They were 0.3 to 0.6 feet in diameter at the base and were set about two
feet apart on an average. An interior hearth near the center of the
house was probably circular in shape and an estimated three to four feet
in diameter. Its exact dimensions could not be determined because of
disturbance by the pothole. No interior post molds were found.
Remains of an extended entranceway on the west side of the house
consisted in five post molds which outlined the two parallel sides of
the entranceway. The entranceway was slightly less than three feet wide,
and it sloped downward from the surface of the floodplain into the house
pit.
Burned poles and burned clay daub with wattle impressions showed that
House No. 4 had been destroyed by fire.
