Archeological Survey and Site Testing of the Proposed SR 20 Bridge Replacement over Walnut Creek, Henry County, Georgia

Southeastern Archeological Services, Inc conducted an archeological survey within the project corridor for a proposed State Route (SR) 20 bridge replacement over Walnut Creek in Henry County, Georgia. The survey was designed to locate and evaluate archeological sites that could be adversely affected by the proposed project. Portions of four archeological sites were found within the proposed area of potential effect (APE) (Table 1). One of these, site 9HY322, is a prehistoric lithic scatter that probably dates to the Archaic period. Another, site 9HY321, dates to the Middle Archaic and possibly the late Early Archaic period. It also yielded a recent historic period isolated artifact that is not related to any historic period structures or occupations. Another of the four, site 9HY320, has both prehistoric and early twentieth century components and is almost completely within the APE. The fourth, site 9HY323, has an early twentieth century component. The portions of sites 9HY320, 9HY322, and 9HY323 that lie within the APE have been severely compromised by post depositional disturbances and have no archeological significance. Only site 9HY321 was deemed as having the potential to contain significant archeological deposits. Subsequently, the portion of site 9HY321 within the APE was evaluated through Phase II testing. Prior to testing, sites 9HY321, 9HY322, and 9HY323 were of unknown eligibility because they extend beyond the APE. Through Phase II evaluation, the portion of site 9HY321 within the APE was found to be well preserved and to contain significant archeological deposits. Therefore, we have recommended it as eligible for listing on the National Register of Historical Places (NRHP). The site should be avoided to prevent any adverse effects from the proposed project, or the adverse effects to the site will need to be mitigated.
