These four corner-notched arrow points were recovered from a Keith phase Early Ceramic period archeological site in Pawnee County. The notches aided in hafting the point to the arrow shaft. The arrow point on the left is made of basalt, the two arrow points in the center are made of Smoky Hill silicified chalk which outcrops in western Kansas and Nebraska, and the arrow point on the right is made of Florence chert from the Flint Hills region.
