This is a
thick small to medium triangular side notch point with
an elliptical cross section. The blade is may vary from excurvate to straight.
Broad shallow notches are ground and create weak
shoulders at an upward angle. The stem is broad and expanding with a straight to
strongly convex base. Basal grinding is
commonly seen on this point. This point
commonly is crudely made and has a random flaking pattern.
Size Measurements: 30 to 60 mm (average
40 to 50 mm), Stem Length - 11 to 15 mm (1/4 to 1/3 the total length),
Width - 20 to 25 mm (the width of the blade and the stem are fairly
close. Some examples have a slightly narrower stem than blade
while others they are the same width), Neck Width - 15 to 20 mm (Suhm and Krieger, 1954).
