After further study, it appears that this is one of a series of small circular holes in the bedrock possibly associated with quarry machinery in the form of cranes or other lifting mechanism. Given the limited ceramic content of the fill, their tentative association with this phase of activity is based on their location, size, and arrangement, rather than their stratigraphic relationships to other features or their finds.

Cut of a potential posthole which could be related to the linear feature on its western side and to the other potential posthole on its southwestern side.
