The Genesee Valley has long been recognized as a center of Iroquois development, but the connection between Owasco sites in the Genesee and Iroquois sequences in the adjacent regions has never been adequately demonstrated. Attempts to identify transitional Owasco-Iroquois sites in this region have been hampered by the use of diagnostic criteria based on data from eastern New York. This article examines ceramic patterns in the Genesee and establishes a regional cultural sequence based on ceramic criteria which have local diagnostic significance. This sequence reveals the transition from Owasco to Iroquois culture begins in the Genesee with a sudden influx of Ontario Iroquois ceramic traits from the west ca. 1250 A.D. This Owasco-Ontario Iroquois connection in the Genesee negates certain assumptions regarding Iroquois origins and alters our current concept of in situ development.
