Snyders Corner-Notched/Manker Corner-Notched

Snyders CornerNotched /Manker Corner-Notched Snyders Corner-Notched points are named after the Snyders site, Calhoun County, Illinois. Manker Corner-Notched points are distinguished from Snyders points in examples found at the Manker site, Illinois. other possible names or related points: Snyders Notched, Hopewell points. age: 2,200 to 1,800 .. distribution: These points are found throughout the Midwest but are most common in central and northern Illinois, eastern Iowa, southwestern Michigan, eastern Missouri, and southern Wisconsin. They are also known from the Ohio and Mississippi river valleys but are uncommon in the Upper Mississippi Valley . Some examples, however, have been recovered from floodplain islands near Prairie du Chien, Wisconsin, and interior settings such as within the Kickapoo and Root river valleys. description: These types are distinctively large, broad corner-notched knives made from oval bifaces. Snyders points are well made with broad bifacial thinning flake scars and convex edges. They tend to be associated with mortuary settings . Manker points are usually less refined, with straighter edges. Shoulders have blunt barbs. Basal edges are convex on Snyders points but may be straight on Manker points. Basal grinding is absent. The notches are broad and oval. Stems are short and only half as wide as the shoulders. A major difference be1 cm 3 recto running foot | 67 tween these two point types is that Snyders points generally have large corner notches and Manker points tend to be more stemmed or open-notched. Length: 5–15 cm/2–6 in. Width: 5–10 cm/2–4 in. (Snyder) Length: 5–10 cm/2–4 in. Width: 2.5–5 cm/1–2 in. (Manker) material: These points are usually made of flints found in the southern range of the Midwest, such as Burlington chert, although examples made of local Prairie du Chien chert and silicified sandstone have been found in the Upper Mississippi Valley. Snyders points are sometimes heat-treated. Some examples are documented as having been made of Knife River flint, including several associated with Hopewell burial mounds between Prairie du Chien and Trempealeau.Other western exotic flints (including obsidian, speckled [dendritic] jasper, and Morrison siliceous sediment) were also imported and used exclusively for Hopewell mortuary bifaces in this region, and some of these are related to the Snyders type. references: Bell 1958; Boszhardt 1998b; Justice 1987; Logan 1976; McKern 1931; Montet-White 1968; Morrow 1984; Ritzenthaler 1967; Scully 1951; Thomas 1894. 68 | middle woodl and broad corner-notched points ...
