In this interpretation, the flood waters of the first event, the Algonquin, surged southward. In the later, Ontarian event, powerful floods streamed southwestward along the basins of Lakes Ontario and Erie. Bedrock fluting, upstream-pointing noses on escarpments, and tunnel channels give supporting evidence for the regional flood hypothesis. Regional distributions of drift thickness may be explained by this hypothesis. This content is PDF only. Please click on the PDF icon to access.
