This rare occurrence has only been documented at a few archeological sites in North America (Callahan 2003; Keyser and Klassen 2001; Riggs 2001; Sutherland and Steed 1974; Thomas and Thomas 1972).

Flaking: Usually collateral; can be random, chevron, or oblique. Notching: Moderate to deep, placed relatively low on the lateral margins above the corner; typically U-shaped and horizontal, but sometimes with an upward angle. thesis, Department of Anthropology, Northern Arizona University, Flagstaff.

Breaks through the neck between the notches are common. (2005) Projectile Points as Indicators of Preceramic Occupation of the Coconino Plateau.

Materials: Chert, quartzite, basalt, rhyolite, obsidian, and other materials. (2002) Stone Age Spear and Arrow Points of the Southwestern United States.

Other Names: Bitterroot Side-notched, Large Side-notched. Comparisons: Differentiated from Sudden Side-notched points by basal morphology: Northern Side-notched points have concave bases and Sudden Side-notched points have contracting to well-rounded bases.

The XRF dates provide a mean age of 2,750 plus or minus 700 calendar years before present for these images (and also provide an indirect basis for dating the other similar figures).
