Abstract
Pleistocene epoch in arctic Canada involved a succession of 2 or perhaps 3 glacial and interglacial intervals. Some areas were apparently not overridden by ice during the latest (Wisconsin) invasion. Pre-Wisconsin surficial features are mainly found outside the areas of Wisconsin glaciation, on the western Queen Elizabeth Islands, Banks Island, and on the arctic coastal lowlands of the Mackenzie River and Yukon basin. The Beaufort formation of late Tertiary or earliest Pleistocene age is very widely distributed and may be equivalent to the Gubik formation of the Alaska coastal plain and the various unconsolidated sands, silts, and gravels of the arctic coastal lowlands. Within the area covered by the Wisconsin Laurentide ice sheet there are many striking glacial features including molded rock surfaces, crag-and-tail hills, esker complexes, and raised shorelines. A distinct pattern of deglaciation can be recognized with many proglacial lakes. Sea level changes, readily observed from beach deposits and marine shells, record the uplift during and following the wastage of the last major glaciation. Available radiocarbon datings in arctic Canada are given in summary in a table.
