Daniel Zulandt's M.A. thesis (Zulandt 2010 - available online here) contains plan maps of the 1957 and 1958 excavations at the Zencor Village site (33-Fr-8) in Franklin County, Ohio.  Those excavations exposed the remains of at least three post structures dating to somewhere in the period A.D. 500-1000.  Raymond Baby and colleagues mentioned the existence of these structures in several short papers (e.g., Baby 1971; Baby and Shaffer 1957; Mays and Baby 1958), but with scant details:

"The remains of at least three houses . . . The structures represented by the postmolds were 25 to 36 feet in diameter, with an overlapping wall serving as an entrance.  The postmolds averaged 0.6 feet in diameter and were set in the ground 1.5 feet deep and 2.5 feet apart" (Baby 1971:196).

The plan maps reproduced by Zulandt (2010:Figures 5, 6, and 7) show the post structures and their relationships to features at the site.  I don't know that these maps were not available elsewhere prior to Zulandt's thesis, but this is the first place I have seen them and I think it is useful to point out their existence. 

I already had an entry for the Zencor Village site in the database.  In the next issues of the database, however, there will be one entry for each structure.  The dimensions of each structure will be estimated from these drawings.

Jarrod Burks' dissertation, entitled Identifying Household Cluster and Refuse Disposal Patterns at the Strait Site: A Third Century A.D. Nucleated Settlement in the Middle Ohio River Valley (Burks 2004), considers how patterns of trash disposal can be used to assess the contemporaneity of residential structures.  Jarrod examines artifact density data from shovel probes in  light of a model of household-level trash disposal developed from ethnoarchaeological data, then compares the results to geophysical and excavation results.  Portions of two structures were exposed.  I have added a listing for the Strait site to the inventory for Ohio, and will include the site in the next version of the Database. 

The Strait site (33-Fa-156-158) is one of only a handful of "Middle Woodland - Late Woodland Transitional" sites in the Database.  Sites of this age (i.e., arguably post-Hopewell, generally associated with projectile points belonging to the Lowe Cluster) are sometimes referred to in the literature as "late Middle Woodland" and other times as "early Late Woodland."  Hence my decision to give them their own category.  These sites represent a time of important change in the organizational structure of settlement during the Woodland period in the Ohio Valley.  Read Jarrod's dissertation to find out more.
