These eight arrow points were found in Lyon County and donated to the Kansas Historical Society in 1958. They are made from assorted materials in different styles: triangular, side-notched, corner-notched, and one single corner-notched or preform. The dates for the different styles range from the Early Ceramic Period (corner-notched points) to the Middle Ceramic Period (side-notched points) to the Late Ceramic Period (triangular).
