Abstract
Drift ice processes have been active in the James Bay area, Subarctic Quebec, since the melting of the last Pleistocene ice-sheet, about 8000-7000 years B.P. Abundant and varied features resulting from ice action are found in the following sedimentary environments: littoral and marine, fluvial and estuarine, and lacustrine. They include rafting of sediments, ice-pushed boulders, stone pavements, boulder ridges, shore ice kettles, erosional features in tidal flats and tidal marshes including longitudinal furrows and circular depressions, drift ice striations and scratchings on boulders and soft rock outcrops, collapsed depressions resulting from the melting of buried ice in tidal flats, and uprooted and overthrown shrubs and trees along river banks and lake shores. Erosional and sedimentological effects of drift ice are of prime importance in tidal flats today. Conditions being equal, it appears that drift ice processes are more active in subarctic regions that elsewhere in Canada.
