to the mountain glacierization of the east coast (Falconer, 1962) for it can be 

 shown that the mountains were at least partially inundated by the outlet 

 glaciers of an extensive inland-ice with its centre over western Baffin Island 

 and Foxe Basin (Ives, 1962; Andrews and Ives, 1963). The development of 

 this inland-ice was the predominant factor in the extent of the glacial inunda- 

 tion of the fjords and coastal mountains and in this instance the close parallel

with glacial conditions in Labrador-Ungava is stressed. Thus the Clyde 

 lateral moraines, which mark the upper known limit of the outlet glaciers in 

 the eastern Baffin fjords, are compared with the Saglek lateral moraines of 

 Labrador-Ungava. Secondly, an extensive system of end moraines has been 

 traced over a distance of 700 km. They lie inland from the heads of the 

 fjords, but have many arcuate extensions (convex eastwards) implying that 

 outlet glaciers descended to tide-water. These have been named the Cockburn 

 end moraines and their extensive development and degree of continuity 

 (Fig. 7) prompt the suggestion that they may have full stadial, or at least
