This study is an in-depth analysis of the Lithic Artifacts excavated at the Pollock Works (a hilltop enclosure located outside Cedarville, Ohio). It is my intent to conduct a detailed analysis of the lithic artifacts from the Pollock Works in order to test the following hypothesis: Chipped stone artifacts at the Pollock Works are primarily from local and semi-local sources because these artifacts represent construction activities at the site rather than ceremonial practices. If the chert artifacts and flakes were primarily ceremonial, they would be comprised of primarily exotic cherts.I macroscopically analyzed the lithics excavated from Trench R and Trench T at the Pollock Works, 33 Gr 5, by Dr. Robert V. Riordan and Field School participants from Wright State University in Dayton, OH. Analysis concentrated on the identification of the types and sources of chert in the sample, using the Wright State classification scheme.This study is significant to the understanding of whether the Hopewell who built the Pollock Works used certain chert types in the construction of the earthwork versus the ritual aspect of the site. It was also important to analyze these lithics in order to help make inferences about the use of the Pollock Works. This study will eventually be useful to the final site report on the Pollock Works. It will also be a valuable reference tool for archaeologists studying the Pollock Works. / Department of Anthropology
