This project was a reanalysis of the prehistoric ceramic collections from two important archaeolegical sites in east central Indiana: Mounds State Park (12-M-2) and the New Castle Site (12-Hn-1). Brief summaries of the two sites and their excavation histories are provided as well as summaries of the various pottery types involved. Specific attention is given to the New Castle Incised type.Previous interpretations regarding the ceramics from the two sties are given, and research from this project has provided new interpretations and information. Specifically, a statistical analysis was conducted, and the results show that the pottery from the two sites was made by peoples of the same culture. However, subtle changes were taking place in the manufacture of the pottery, primarily in the plain sherds.Future research goals are provided and include further excavations at both sites, thermoluminescence dating of sherds and additional study of the plain sherds. / Department of Anthropology
