Diachronic changes and continuities in the general occupation patterns and associated subsistence remains represented at a single Georgia coastal archaeological site are defined based upon preliminary investigations at Bourbon Field on Sapelo Island. A series of sociocultural hypotheses are presented to interpret the observed patterns and to provide problem orientations for future research. It is concluded that the community patterns reflect gradual population growth, increasing sedentism, and increasingly complex social arrangements. Estuarine and oak-forest species are identified as being of continuing importance as primary subsistence resources.
