Age of landslides along the Grande Rivière de la Baleine estuary, eastern coast of Hudson Bay, Québec (Canada)
A 12km long terrace along the estuary of the Grande Rivière de la Baleine, northern Québec (55d̀17'N, 77d̀47'W), has been locally modified by seven large landslides during the last 3,200 14 C years. The oldest undated landslide occurred between 3,200 B.P(formation of the upper terrace) and...
