Lithic Refitting and Archaeological Site Formation Processes

A Case Study from the Twin Ditch Site, Greene County, Illinois
  • Toby M. Morrow
Part of the Interdisciplinary Contributions to Archaeology book series (IDCA)


The lithic assemblage recovered from Horizon 2 of the Twin Ditch site is the focus of an ongoing refitting study and provides the data employed in the analysis presented here. The abundance of lithic tools and manufacturing debris recovered from this relatively pristine Early Archaic base camp has allowed for the reassembly of numerous broken stone tools and for the reconstruction of several chipped stone tool manufacturing episodes through refitting. These refitted artifacts provide a wealth of spatial and technological data that can be applied to numerous archaeological research questions. More specifically, the refitted tools and debitage from Horizon 2 provide details concerning archaeological site disturbance processes, modes of refuse accumulation, and the occupational history of the site. The results of the present analysis indicate that the Horizon 2 cultural deposits have been subjected to minimal post-occupational disturbance, that lithic debris accumulations on the site represent both primary knapping loci and secondary refuse deposits, that at least two distinct occupational episodes are represented on the site, and that the individual occupations of the site were probably of relatively short duration.
