Abstract
Three succeseive sites on the northern shore of Georgian bay of Lake Huron are incorporated in deposits of raised beaches at elevations of 297, 56 and 27 feet above the present lake. The stratigraphy of these sites presents a complicated record that involves postglacial uplift of the Lake Huron basin along with rising and falling levels. This geology is outlined. The highest (oldest) site has only artifacts of Scotsbluff type and is about 9000 years old. It was occupied during a drop from the level of Lake Algonquin. After a further drop, the beach at the intermediate site was formed 8500 years ago. This drop culminated in the low stage known as Lake Stanley, which was below the lowest archaelogic site. Lake level then rose and again reached the intermediate site 6500 years ago. Artifacts in beach gravel at this site could be either 8500 or 6500 years old. The high level of Nipissing Great Lakes was reached 4200 years ago. As a result of uplift, the intermediate site was raised to the Nipissing level 3800-3600 years ago as was shown by woodland artifacts in sand on the beach gravel. Receding water levels passed through the Lake Algoma stage 3200 years ago and then built the beach at the lowest site. Artifacts at this site indicate that Adena-like occupation older than about 2200 years gave way to Point Peninsula occupation. The lake thereafter receded to the present level.
