Description of Physical Characteristics and Flaking Pattern:
This is a thin small to medium triangular point with a flattened cross section. The overall shape may vary from an isosceles triangle (twice the height as width) to equilateral triangle (same height as width). The blade is most commonly excurvate, but many examples have straight blades and fewer have incurvate blades. The base may range from slightly concave to slightly convex. This point has a random flaking pattern.
Size Measurements:
Total Length - 11 to 53 mm (average 21 to 25 mm), Width - 6 to 18 mm (average 10 to 13 mm), Thickness - average 3 to 5 mm

Additional Comments:
This is a cache all type that includes many variations. Variations include isosceles triangles with straight, concaved as well as convex bases as well as equilateral triangles. Blades have as many variations as the bases ranging from incurvate to excurvate. So far there have been no significant attempts subdivide this type into subtypes based on flaking techniques or materials (Justice, 2002).
