More on deep glacial erosion by continental ice sheets and their tongues of distributary ice

Description :
High latitude intracontinental seaways occupy great troughs carved by broad tongues of inland ice as it debouched to deep marine water. Such troughs occur in glaciated coasts, but not in stable, nonglaciated ones. Where ice flowed across them, coasts are digitate in low relief. In the northeastern sector of the Laurentide Ice Sheet, large glacial grooves converge toward the Gulf of Boothia - Prince Regent Inlet - Lancaster Sound, suggesting that it was an exit for inland ice which shaped it to its present form.
