- Comments
- Beausejour Bayonet, BlDb-10: D. Keenlyside reports that an in situ tree stump was exposed at low tide, at the base of a steeply sloping beach where the beach begins to level off. It was about 75 meters below the dyke. The tree stump (GSC-6627) was closely associated with cultural finds. A walrus baculum removed from an organic sandy matrix several meters away, but at same stratigraphic level, was dated by Beta-139755. A surface collection of 46 stone plummets in immediate area of stump, and at the same stratigraphic level, typologically date to 3500-4500 BP (Maritime Archaic). The tree stump is part of a drowned forest which is closely associated with a human occupation. Thus its ecological context, and palaeoenvironmental interpretations (vegetational, climatic, and sea level implications) are significant for the Maritimes and the northeastern seaboard.
