Abstract Along the geographic edges of regional populations lies latent potential for innovation and change accruing from interactions with those beyond the edges. This arguably was the case among some of the first pottery-making communities of the American Southeast. Centuries of interactions between these mobile communities and those beyond the geographic distribution of early pottery in the Savannah River valley culminated in places of permanent residence and ritual gathering at the overlapping edges of settlement ranges. Coupled with geochemical data on clay provenance, petrographic thin sections of Stallings fiber-tempered pottery register changes in social affiliation attending the emergence of gathering places. Despite continuity in the use of fiber for temper, innovations in the decoration and form of Stallings pottery coincide with changes in clay provenance and mineral composition to suggest a reorientation away from ancestral ties downriver and towards novel connections upriver. New relationships at the overlapping edges of ancestral lands were brokered at places of settlement and mortuary activity, notably at Stallings Island, which was abandoned for as much as three centuries after pottery appeared in the region. Revealed by petrographic data on the choices potters made in either maintaining or reinventing tradition is perspective on the ceramic social geography of Classic Stallings Culture that has implications for studies of social networks worldwide.
