AbstractRecent field investigations have been undertaken to map the surficial geology of Bathurst and adjacent islands. Glacial geomorphology indicates that the area was covered by extensive ice caps during the last glaciation. These glaciers probably contacted the Laurentide Ice Sheet to the south, however, a larger ice mass in Penny Strait may have impinged onto northeastern Bathurst Island and coalesced with the ice caps. A survey of raised marine shorelines suggests that the magnitude of emergence was considerably less than previously thought and that the pattern of regional isobases needs revision. Marine pelecypods at elevations well above the marine limit were likely transported there by glaciers overriding pre-existing marine sediments. More work on the directions of ice movement along eastern Bathurst Island is necessary to determine the nature of these readvances.
