In addition to the two center molds, there were two other post molds within the interior of the houses at Mound C. One was just east of the hearth area, the other was northwest of the hearth ([Fig. 8]). Both were exposed in the excavation floor at the level of House No. 1, and since they were not encountered above that level both probably relate to the earlier house.
An extended entranceway on the west side of the houses was delineated by an elongated area of organically stained soil and by two parallel rows of post molds ([Fig. 8]). The stained area was clearly discernible in the mound fill above both house floors. Despite extremely careful excavation of this stained area, however, only the bottom portions of the post molds—well below the floor level of House No. 1—could be seen. Consequently the level from which the entranceway post holes were dug could not be determined and it is uncertain to which of the two houses they belonged. House No. 2 must have had its entranceway on the west side because the organically stained outline showed clearly in the mound fill well above the House 2 floor level. Possibly both houses had their entranceways in this same area.
House No. 2
House No. 2 was represented by a distinct floor zone and by a circle of post molds. The floor zone ([Fig. 8]) consisted of a lens of brownish sand averaging about 15.5 feet in diameter, with a maximum thickness near the center of almost a foot. It lay directly above the floor of House No. 1, but was separated from it by a thin layer of clean, sterile sand 0.1 to 0.3 feet thick. The sterile sand layer was possibly placed over the burned ruins of House No. 1 in order to provide a clean floor for House No. 2.
The peripheral ring of post molds ([Fig. 8]) averaged a little less than 14 feet in diameter (or almost four feet less than that of the underlying House No. 1) and lay entirely inside the exterior wall of House No. 1. The two rings were not quite concentric, however, the center point of House No. 2 being slightly to the west of the center point of House No. 1. The post molds of House No. 2 were from 0.45 to 0.85 feet in diameter, and they extended from 1.6 to 2.0 feet below the level of the related house floor. Several of the molds were sectioned vertically to determine the level from which they had been dug. They could be clearly traced from the floor of House No. 2 down through the floor of House No. 1 into the sub-mound floodplain.
As was pointed out above in the description of House No. 1, there was probably a circular, centrally located hearth associated with House No. 2, and one of the two center posts whose molds were found beneath the hearth area must have been used in the construction of the later house. There appeared to be no other interior post molds associated with House No. 2. The entranceway was probably on the west side.
DISCUSSION
Excavation of Mound C revealed that a circular house (House No. 1) was built on the south bank of the Harroun Site lake, was occupied for an unknown period of time, then was burned—perhaps intentionally. After a thin layer of sand had been strewn over the burned ruins, a second, smaller house (House No. 2) was erected on the remains of the earlier house. House No. 2 was likewise destroyed by fire, after which the remains of both houses were buried under a mound of sand.
Both houses probably had centrally located hearths, and one or both of them had an entranceway opening to the west. As at Mound B, a low pile of sandy soil may have been banked around the outside of one or both houses before they were destroyed. Architecturally the houses at Mound C were quite similar to the one at Mound B.
The sparse occurrence of artifacts and other cultural refuse suggests that neither House No. 1 nor House No. 2 was an ordinary domicile. It appears likely, rather, that both were ceremonial structures of some sort. This hypothesis is supported by the fact that the houses were considered important enough to be afforded burial beneath a mound, probably after having been ceremonially “cremated.”
