Abstract
Detailed ice-flow and surficial mapping of Newfoundland, application of new dating methods, and an expanded data set of both raised and submerged sea-level records allow a re-appraisal of Late Wisconsinan ice-limits. Ice flow mapping confirms and refines the hypothesis of multiple island-based ice centres, allowing better definition of the location of these ice centres, as well as outlining the sequence of disintegration and deglaciation. Ice flow mapping, offshore mapping and absence of pre-Late Wisconsinan dated material tend to favour maximum models of ice extent. There is increasing evidence of ice filling the Gulf of Lawrence, and extending out towards the edge of the Continental Shelf. Dating of known glacial re-advances indicates that while the Ten Mile Lake re-advance might relate to the Younger Dryas, the Robinson's Head re-advance is older, and is likely not climatically controlled. The identification of a sea-level low stand over much of the southern and northeastern parts of the Island has resulted in revision and clarification of the sea-level history, and an increasing number of radiocarbon dates and detailed studies allow regional patterns to be identified.
