Description of Physical Characteristics and Flaking Pattern:

This is a small to medium triangular corner notched point.  The cross section is most commonly flattened, but occasionally may be elliptical.  The blade is primarily straight, but may range to incurvate in examples with flaring shoulder edges.  The blade is rarely excurvate.  The blade is commonly beveled on one or both edges and finely serrated.  The shoulders range from straight to barbed.  Rarely the shoulders have an upward angle (clipped wing).  The stem is very short and expanding due to the removal of the fracture flakeThe base is most commonly slightly concave, but may also be straight.  The base will rarely be convex.  The base is usually ground and thinned.   The flaking pattern is random with a serrated blade.
