Hells Canyon Corner Notch Point

This triangular corner notch point exhibits a compact to moderate size profile, characterized by an elliptical cross-sectional shape. The blade edge displays a range of curvature, from gently excurvate to straight, while the shoulders present a varying degree of barbing, with some specimens featuring subtle, rounded terminations. The stem is notably short and expands outward, providing a sturdy foundation. The basal edge is variable, spanning from straight to convex, with basal corners that are consistently rounded. The flaking pattern observed on this point is random, lacking a discernible, organized arrangement.

The dimensions of the arrowheads are as follows: they range in overall length from 24 to 57 mm, with stem lengths varying between 5 and 10 mm. The width of the blade spans from 17 to 32 mm, while the neck width measures between 8 and 14 mm. Additionally, the stem width is recorded to be within the range of 10 to 19 mm.

This type is mainly discovered on the Columbia Plateau, extending into Oregon's Cascade mountains, across the Snake River valleys, and throughout the northern Great Basin region
