St Croix Point

This corner-notched projectile point exhibits a slender profile with a compressed cross-sectional morphology. The blade's curvature is predominantly excurvate, while the notches are of moderate depth and exhibit a high degree of craftsmanship, forming pronounced shoulders that terminate in barbed edges. The stem is expanding, and the base, although generally convex, can occasionally approach a straight configuration, often displaying a distinctive "Dovetail" morphology. Notably, the base typically lacks basal grinding. The point's manufacture involves pressure flaking, resulting in a random, non-patterned flaking arrangement.

The dimensions of the arrowheads are characterized by a total length ranging from 19 to 40 mm and a blade width spanning from 11 to 20 mm.

This style is mainly discovered in the Snake River / St. Croix river valley of Minnesota and Wisconsin. Morrow (2016) notes its presence extending into northern Iowa.
