The middle Woodland pottery from Area 3 at the Pointe-du-Buisson site exhibits a complex of diagnostic behaviour traits which lead us to postulate that this locality was frequented at different times by Amerindian groups who shared a variety of techniques but differed in their choice of decorative arrangements. Insofar as pottery attributes are concerned, Area 3 is unique in that we find here, concentrated in one place, a number of cultural manifestations that occur only as separate and distinctive entities in other regions such as southern Ontario, the State of New York and the Ottawa Valley.
