Description of Physical Characteristics and Flaking Pattern:
This is a thin medium to large triangular corner notch point with a
flattened elliptical cross section. The blade is thin (commonly
6:1 to 10:1 width/thickness ratio), broad and may vary from excurvate to recurvate. Blades may vary from
having an almost ovoid shape with the tip curving in and curving back in at the shoulders, to an excurvate blade, to having
incurvate blade. Re-sharpening reduces the blade and shoulders. Many examples have
bi-facial alternating left hand beveling commonly giving the blade an
asymmetrical appearance. The blade is usually finely serrated.
Small narrow notches enter the corners of the preform forming a shoulder
that is strongly barbed and may extend to the base. The stem is short, wide and expanding. The base is primarily concave, but may vary to recurvate (as is shown in the outline), to being
almost straight or slightly convex. Basal and hafting region grinding is generally present.
This point is manufactured using percussion flaking with pressure
flaking used to thin, shape, and sharpen the blade forming a random flaking pattern.
Size Measurements: Total Length - 40 to 95 mm
(average 60 to 70 mm), Stem Length -6 to 12 mm, Blade Width
- 25 to 46 mm, Neck Width - 17 to 28 mm, Stem Width - 18 to
34 mm.
Distribution:
Distribution Comments:
This point is primarily found in the Ohio River valley with high
concentrations throughout Illinois. This point is found into the
Tennessee River valley with decreased frequency. Morrow (2016)
notes that these points are also found into central Iowa and
southern Wisconsin. These points have not been found into
Minnesota, but he notes that they have a high probability of being
in southeastern Minnesota.
Additional Comments:
Conrad felt that these points represented a variant of the Kirk Corner Notch and the Decatur type points (Justice, 1987).
