Late Quaternary Glaciation of the Eastern Queen Elizabeth Islands, N.W.T., Canada: Alternative Models
It has been suggested that during the last glaciation the Innuitian Ice Sheet existed over the eastern Queen Elizabeth Islands. This is based on the pattern of postglacial emergence over this area and the timing of driftwood penetration into the interisland channels. Alternative interpretations of b...
