Pollen-bearing Erie Interstadial sediments from near St. Mary's, Ontario

The Wildwood Silts, of Erie Interstadial age (16000 BP), occur between Catfish Creek Till (Nissouri Stadial) and Tavistock Till (Port Bruce Stadial) near St. Mary's, Ontario. Pollen analysis of a 16-m core through the silts yields a pollen assemblage dominated by pine and spruce pollen, resembling those reported from Port Talbot II and Plum Point Interstadial sediments in Ontario. A forest–tundra environment is inferred at the time of the Erie Interstadial, with generally sparse vegetative cover.
