Summary: | This paper comments on preconceptions about what is meant by the terms "Cordilleran Ice Sheet" and "ice stream". Contemporary Antarctic ice streams are described. The Laurentian Channel and throughs crossing the continental ice shelf between Vancouver and Queens Charlotte Islands are suggested as candidates for the tracks of past ice streams. On discute ici de préconceptions sur la signification des termes « Inlandsis de la Cordillère » et « courant glaciaire ». On décrit d'abord les courants glaciaires contemporains de l'Antarctique. On désigne ensuite le chenal laurentien et les dépressions qui traversent le plateau continental entre Vancouver et l'archipel de la Reine-Charlotte comme des endroits susceptibles d'avoir été, dans le passé, la voie de courants glaciaires. |
