SHAPE: These lanceolate points have "eared" concave haft elements, exhibiting basal and lateral grinding and basal facial thinning usually attained by the removal of one or More parallel-sided flakes. There is considerable variability in blade shape, largely due to resharpening. Unresharpened or little resharpened points have excurvate blade edges with maximum width and thickness at blade midpoint, a biconvex to plano-convex cross-section and a slight shoulder at the blade element-haft element juncture. Resharpened points have straight to incurvate lateral edges, maximum width and thickness at the top of the lateral grinding, a biconvex to "twisted" parallelogram cross-section and little or no shoulders.

FLAKING: Unresharpened specimens exhibit a well-executed collateral to rough parallel flaking but resharpened points show little consistent pattern to removals. 66% of the available sample exhibit edge beveling, predominantly on the left and on alternate edges.

RAW MATERIAL: Onondaga, Haldimand and Kettle Point chert are the predominant identifiable materials on Ontario sites.

DISTRIBUTION: Hi-Lo points are found throughout south-western Ontario and along the north shore of Lake Ontario. They also occur in Michigan, Wisconsin, and possibly, Minnesota and Northern Illinois.

AGE & CULTURAL AFFILIATIONS: Hi-Lo points are considered. to be a late PaleoIndian point form. The combination of a lanceolate shape and a high incidence of edge beveling occurs elsewhere only on Dalton points (Chapman 1948), and its regional variants such as San Patrice-Hope (Duffield 1963). These forms are dated between 10,500 and 9,500 B.P.

REMARKS: Point blade elements can be reworked into end scrapers and perforators and are sometimes laterally notched.
