Instructions
Note the region where the arrowhead came from. You probably won't find an Appalachian arrowhead in the Piedmont or Coastal regions, so being aware of where the arrowhead was located will help you narrow down the type. If you are purchasing an arrowhead, ask for this information and make detailed notes of where the collector found the piece. Consider detailing this information in a logbook and take it with you on any expeditions.
Examine the arrowhead using a magnifying glass for closer inspection. The overall shape can be triangular or resemble a leaf. An arrowhead can have a flared shoulder edge, an expanding stem or a concave base. The projectile bottom, or "stem," can be smooth or notched. E-notches at resemble the letter E. Convex bases are wider than the projectile shape.
Compare the shape of your arrowhead to the shapes provided in classification guidebooks or charts online (see Resources). For example, an arrowhead you find in any region of North Carolina that has an expanding notched stem with a triangular projectile shape is a Big Sandy arrowhead.
