Description of Physical Characteristics and Flaking Pattern:

This is a narrow small triangular corner notch point with a flattened to narrow elliptical cross section.  The blade is commonly thin and may vary from slightly excurvate to straight.  The shoulders are barbed with an expanding stem.  The base may range from straight to convex.  This point has a random flaking pattern.

Additional Comments:

These point represent the first true arrow point and the transition to the bow and arrow technology in the Great Basin (Justice, 2002).

The Corner Notch, Side Notch, and Stemmed variation of this point may represent continuum of the same technology.  The difference between the corner notch and side notch types may be the degree of re-sharpening of the blade which reduces the shoulder and notch placement in order to maximize the basal region.  The stemmed variation commonly has a slightly expanding stem varies from the corner notch by the degree of expansion of the stem which may be a result of notching accident or the size and sharpness of the notching tool.

David H. Thomas (1981) combined the Rose Springs type and the Eastgate types into a single type due to the overlapping characteristics of the two types.  He used a contracture of the two points and formed the Rosegate Cluster.

This point is similar to the Eastgate point, but this type lacks the square barbs typically seen on the Eastgate points.  This point is usually narrower than the Eastgate points.  Both types are the extension of the Elko Corner Notch type, but evolved to better fit the change in technology from the dart points to the arrow points.  Desert series points and Cottonwood points replaced this type of point (Justice, 2002).
