The mixture of Late Woodland and Fort Ancient ceramics found on sites in central Indiana has presented a problem for archaeologists for over fifty years. This unique combination of ceramic traits has become known as the Oliver Phase. Materials recovered from the Bowen Site, (Dorwin 1971) have in the past been used to define this phase. Originally, the Bowen Site was believed to represent the excavation of an entire synchronically occupied prehistoric site. A reanalysis of the distribution of diagnostic ceramic attributes from the Bowen Site suggests multicomponent occupations resulting from diachronic settlement. Therefore, the full range of ceramic variation originally attributed to this phase needs to be reexamined in the light of this new information, and it's usefulness as a diagnostic assemblage should be carefully evaluated. / Department of Anthropology
