These four dart points were collected from a multicomponent (multiple occupations) American Indian camp site in Doniphan County and donated to the Kansas Historical Society in 1925. The dart point's stems are all what archeologists call contracting stems. One dart point gets its pinkish color as a result of the material being carefully heated before manufacturing to improve the chert's knapping qualities. Dart points would be mounted to the dart foreshaft, which would in turn be connected to the dart shaft. The assembled dart would then be thrown with an atlatl (spearthrower).
