Klunk Side Notched is a Late Woodland arrow point of the lower Illinois Valley and adjacent Missouri, named for the Klunk mound group in Calhoun County, Illinois, and dated to about 600–900 CE. It was made from Burlington chert and occurs with Koster Corner Notched on the same sites. It belongs to the earliest bow-and-arrow horizon of the region.

Diagnostic traits
Small, thin triangular arrow point with shallow side notches placed low on the blade and a straight base, often with fine serrations.
Identification
Klunk is side-notched where Koster is corner-notched; both are smaller and thinner than any dart point. Cahokia Side Notched is later, larger and often has multiple notches and a basal notch.
Reproductions and fakes
Seldom faked, though genuine ones are sometimes sold as Cahokia; check for the absence of basal notching.
