Near Killarney, Canada, three raised beaches of former Great Lakes stages have cultural material in circumstances indicating contemporaneity with the construction of the beaches 7000 B.C. and A.D. 1. The physical conditions demonstrating this contemporaneity are set forth in detail, with illustrations of artifacts in situ in gravels. The several components of two sites are distinguished, and a workshop with most of the artifacts in unfinished condition is described and illustrated. The geology, which involves Postglacial uplift of the Lake Huron basin along with rising and lowering levels, is fully outlined.
