Common throughout Illinois, Missouri, Iowa, and southern Wisconsin. Small to medium spear points. Blades are triangular with convex edges. Shoulders are straight to sloping. Basal edge is straight to slightly convex while stem edges are side notched and concave.
Stems expand from the shoulder to the base and account for approximately of the point's length.
Notches are usually longer than wide. Basal edges are rarely ground. These are sometimes difficult to distinguish from Durst points of the Late Archaic. Both are characterized by expanding stems, but the Steuben family usually have sharper shoulders and are made of chert, whereas, Durst points tend to have rounded shoulders and may be made of chert or orthoquartzite.
