Abstract

The Fossmill and the North Bay drainages and the resulting Petawawa and Mattawa deltas correlate the late Wendat Lakes in the Huron basin with the early Champlain Sea in the Ottawa lowland. The large drainages are now regarded as the cause of the erosion surfaces and of the sands which occur between beds of stiff glacial Yoldia-bearing Champlain Sea clays in the Pembroke-Ottawa region. These correlations-Iroquois deltas deposited by a drainage of Lake Algonquin, Algonquin beaches in the northern Michigan basin postdating the Valders glacial maximum at Milwaukee-these and other facts and features prove that several Wendat and Algonquin lake stages intervened between the Champlain Sea and the Valders maximum, and they refute radiocarbon-based conclusions that the early Champlain Sea was contemporaneous with the Valders maximum and the Two Creeks stage, and that Lake Iroquois was of Mankato age. Since the radiocarbon age of 10,850 years of sample Y-216 from Uplands south of Ottawa is compatible with the know...
