Kampsville Point

This triangular point features a stemmed design with an elliptical profile, showcasing a distinctive excurvate blade shape that often curves inward at the shoulders, although repeated sharpening can result in a straighter edge. The shoulders themselves are typically barbed, sometimes extending halfway or even the full length of the stem, but tend to become less pronounced as the point is re-sharpened. The stem's shape can vary, ranging from straight to slightly flared, with a base that may be straight or mildly convex. The basal corners exhibit a range of sharpness, from acute to rounded. In terms of manufacture, the point was created using a combination of techniques, with random percussion flaking employed for the initial shaping, followed by pressure flaking to refine the blade's edge, yielding a characteristic random flaking pattern.

The arrowheads exhibit dimensions within the following ranges: length spans from 20 to 33 mm, while the blade width varies between 10 and 15 mm, and the thickness measures between 2 and 4 mm.

This type is mainly discovered in the southern Illinois River Valley and extending into Missouri.
