Likely a structure was built on the original prepared floor, as evidenced by these substantial post holes. The location of this trench is not known. Two types of mound fill were encountered. The inner mound fill was a distinctive compacted black sand that did not show loadings. Perhaps it was soil from the near-by Lake Ellsenmere. The upper stage contained discontinuous lenses of loams and gravels. These soils are commonly found in this region. Two stages can be seen in photographs but the internal stratigraphy of each is not clear. There is today a hump in a road that goes through a sub-division of Chillicothe that appears to be associated with the mound remnant. However, the nature of the sub-surface physical remains is not known.
