The Summer Island area of the Pleistocene Mackenzie Delta, western Canadian Arctic, is thought to have been last glaciated during the Early Wisconsinan (>35 ka), with a suggested Late Wisconsinan (~13 ka) glacial limit located ~80–100 km to the south. Cryostratigraphic observations in the Summer...
