Hi-Lo
Date Range: 9600-8800 BCE
Dimensions: Hi-Lo points range from 26-59mm in length, 18-29.5mm in width, and 6.5-11 mm in thickness.
Shape: These lanceolate points have “eared” concave to bifurcate base, and exhibit basal and lateral grinding, and basal thinning flakes. There is considerable variability in blade shape, largely due to resharpening. Unresharpened or little resharpened points have convex blade edges with maximum width and thickness at blade midpoint, a lenticular to plano-convex cross-section, and a slight shoulder at the blade element-haft element juncture. Resharpened points have straight to concave lateral edges, maximum width and thickness at the top of the lateral grinding, a lenticular to “twisted” parallelogram cross-section, and little or no shoulders.
Flake Pattern: Unresharpened specimens exhibit a well-executed collateral to rough parallel flaking, but resharpened points show little consistent pattern to removals. Some examples exhibit edge beveling on opposite sides, creating a twisted cross section.
Material: Onondaga, Haldimand and Kettle Point chert are the predominant identifiable materials on Ontario sites. White Haldimand chert was the preferred material.
Distribution and Cultural Affiliation: Hi-Lo points are found in southwestern Ontario and along the north shore of Lake Ontario.
