Abstract Paleoindian sites (approximately 7,500 to 11,500 B.P.) on “raised beach terraces” and “strandlines” in the Great Lakes region are a well-documented aspect of early settlement patterns. In the lower Great Lakes region of Ontario, research on the early (fluted-point) cultures (approximately 9,500 to 11,500 B.P.) has been particularly productive over the past two decades, with survey and excavations concentrated on proglacial Lake Algonquin strandlines (Deller, 1976; Storck, 1982, 1984). Radiometrically dated materials from these beaches were used to establish maximum geological dates for Lake Algonquin strandlines; for sites along the north shore of Lake Ontario there are bracketing geological dates (Roberts, 1984). In the northwestern Lake Superior Basin there is a similar pattern of numerous late Paleoindian (Piano) sites of the Lakehead Paleoindian complex (Fox, 1975, 1980; Dawson, 1983; Julig, 1984,1988) found on or near beaches of an earlier, deeper stage of Lake Superior: Lake Minong (Fig. 1). Prehistoric groups often favored shorelines for settlement sites due to their high biological productivity (and subsistence resources), as well as a ready supply of fresh water. Along the north shore of the upper Great Lakes there are regional loci of Paleoindian sites at coastal locations where there was also abundant lithic material for stonetool manufacture. Several such loci of large coastal quarry/workshop sites, surrounded by numerous smaller sites, include the Cummins site and the Lakehead Paleoindian Complex in the northwestern Lake Superior Basin (Fox, 1975; Julig, 1988), and the Sheguiandah and George Lake Complex of sites in northern Lake Huron (Lee, 1954,1955
