- Comments
- BkGg-11, Allumette Island-1: The site represents the late Vergennes Focus of the Laurentian Archaic tradition. It yielded 1012 copper artifacts, many of them distinctive of Old Copper culture. J.B. Griffin, commenting on the Michigan dates, noted that the result for M-1549 was much too young for Old Copper, and recommended that additional samples be analyzed. This need has been met by the Saskatchewan date which J.V. Wright considers acceptable for a late Vergennes component.
