The valley formed by the Saguenay Graben being oriented more or less parallel to the glacial flow, became a preferred path for ice flow and resulted in deep excavation of the bedrock.The glaciers cut into the graben and widened it in some places as well as making it considerable deeper in others. At the time of retreat of the last ice sheet, the region had been depressed below contemporaneous sea level. As a result, as the Laurentide Ice Sheet retreated, the Saguenay Graben was flooded by marine waters to form the Laflamme Sea. As the land rose in response to considerable

The Chicoutimi (Saguenay) outlier rests against the north wall of the graben and extends southward to a few kilometers from the Saguenay River north of Chicoutimi.
