HOLOCENE EMERGENCE ALONG THE ELLESMERE ISLAND COASTS OF NORTHERNMOST BAFFIN-BAY

The pattern of Holocene emergence at Piliravijuk Bay, innermost Makins on Inlet, south-central Ellesmere Island, is outlined on the basis of radiocarbon age determinations on three samples of marine pelecypod sh ells and eight samples of far-traveled coniferous driftwood. Emergence of at least 100 m, perhaps as much as 120 m, has taken place in the l ast 8800 radiocarbon years. The amount of emergence approaches that do cumented earlier for Cape Storm and South Cape Fiord on the south coas t of Ellesmere Island, and for Cape Herschel on the east-central coast , facing Greenland. This emergence, taken together with the glacial sc ulpture on Bowman Island, the low amino acid ratios in the single vene er of till on the island and on Swinnerton Peninsula, and the fact tha t in situ shells north of the head of the Inlet are similar to 2000 ye ars younger than those at Piliravijuk Bay, suggests that Makinson Inle t was filled with a major outlet glacier Rowing eastward to Baffin Bay in Late Wisconsinan time, The data from Makinson Inlet are similar to those from Cape Herschel, where extensive fieldwork has led to the co nclusion that Smith Sound was filled by a southward-Rowing ice stream in Late Wisconsinan time.
