These represent the earliest demonstrated use of the Mississippi River floodplain. Chesrow points have been reported for counties in southeastern Wisconsin, where they have been inferred to correspond to 12,000 year old butchered mammoths, but none have yet been found in good context. Blades are usually long and narrow with parallel sides which go to a snub point tip. These points have short stems with broad shallow side notches which are never deeper than they are wide. Shoulders are often barely discernible.
Bases are concave and basal ears are small and round.
Basal grinding occurs on some. Points are made from local chert. MVAC Educational Programs are supported in part by the National Endowment for the Humanities .
