These four projectile points were collected from a multicomponent (multiple occupations) archeological site in Wyandotte County and donated in 2002 to the Kansas Historical Society. The site had seen occupations from the Middle Ceramic to Historic periods. All of the points have expanding stems. 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). Arrow points, like the smallest point shown here, were attached to an arrow shaft and fired with a bow.
