Fig. 2. One of several shell lenses exposed during 1973 excavation at the CRBRP Site. Excavations in Area I yielded mollusks from the Plow Zone, and Middle and Early Woodland components. Area II contained mollusks in the Plow Zone and in a buried Middle Woodland component. Area III again had mollusks in the Plow Zone and in a buried Mississippian component, but it con- tained no Woodland materials. Two Early Woodland and three Middle Woodland radiocarbon dates were obtained (Geochron Laboratories Division, Cambridge, Massachu- setts). The Early Woodland component dates between 785-345 B.C., while the Middle Woodland component dates between A.D. 65-625. The first and third dates for the Mid- dle Woodland material were considered by Geochron Laboratories as the best of the three (Schroedl, pers. comm.). The Mississippi component is currently undated, but appears to be Early Mississippian, about A.D. 1100 (Schroedl, pers. comm.). As used in the context of this discussion, Plow Zone refers to the humus and other soil layers disturbed by agricultural activities; Early Woodland and Middle Woodland refer to prehistoric aboriginal groups characterized by small villages or settlements whose subsistence activities depended primarily on hunting and gathering skills; and Mississippian refers to a late prehistoric cultural group who established large permanent villages and who developed agriculture (especially the growing of maize) to the extent that crops played a signifi- cant role in their food economy. The naiads from the excavation units were intially sorted to species and recorded as to right or left valve by straum and area. The total number of valves from the three major cultural components, the Plow Zone, and areas lack- ing provenience are recorded in Table 1. Gastropods from each excavation unit were identified and tabulated at the same time as the pelecypods and are listed in Table 2; this table summarizes the gastropod fauna by cultrual unit. G.F. Schroedl (pers. comm.) is of the opinion that the two Middle Woodland components were contemporaneous; therefore the shell from these have been combined for comparison with the Early Woodland and Mississippian samples.
