Among the numerous problems of morphology in the Quebec section of the St. Lawrence valley, one of the most interesting and debatable problems is the late-glacial and postglacial chronology. The succession of other morphological events depends upon this chronology. How the inlandsis retreated ? When and under which climate ? Were there any glacial recurrences ? What has been the length of the postglacial erosion period ? Was there enough time for the normal erosion to shape the fluvial forms in the bedrock since the ice retreat or not ? These are some of the questions raised in this article.
