Abstract
Geological evidence suggests that an important restricted ice advance occurred along Northwestern Greenland and Northeastern Ellesmere Island during the last glaciation. Detailed records of multiple glaciations and sea level changes are preserved along the coastlines of Smith Sound, Nares Strait, and Kennedy and Robeson Channels. At present the advance of the greenland ice sheet on to northeastern Ellesmere Island is considered inconclusive and, if it did occur, it would have to pre-date the late Wisconsin, and possibly the entire Wisconsin, glaciation. Evidence from glacial geology is also critical for the reconstruction of the time profiles through existing and future ice cores in the region as such data will directly affect the parameters in the flow models chosen. If the ice sheets in the High Canadian and Greenland Arctic were relatively inactive during the last glaciation or glaciations then the ice cores obtained from these areas may be older than originally expected. The chronology of glacial activity during the late quaternary is, therefore, an important source for both the dating and palaeoclimatic interpretation of the ice cores.
