| Summary: | T HE glaciers of the Canadian Arctic are amongst the least known of the northern hemisphere. From the earliest surveys, however, it was clear that they contain numerous features of exceptional interest to the glaciologist. The ice assumes many different forms including glacier caps, highland glaciers grading into vast areas of transection glaciers, valley, cirque, and piedmont forms, and finally some unique shelf ice. It is believed that all this ice has non-temperate geophysical characteristics (Ahlmann, 1948, pp. 66-7) and that, therefore, there is a wide range omf types to study, intermediate between Greenland’s polar inland ice, and the temperate ice of Iceland and Norway. The regimen of the glaciers in the Canadian Arctic is apparently healthier than those studied by Ahlmann around the North Atlantic. The highland rim of northeast arctic Canada was probably the source region from which the Wisconsin Laurentide Ice sheet expanded to cover an area nearly as large as Antarctica in eastern and central North America. At the close of the Wisconsin age the ice disappeared in southern areas and the lowlands of the north, but has persisted as remnants on Baffin, Bylot, Devon |
