These six dart points were collected from an Early Ceramic period archeological site in Atchison County and donated in 1979 to the Kansas Historical Society. Two of the darts were heat treated to improve the chert's knapping qualities. Three of the darts are corner-notched, one has an expanding stem, and two are stemmed. All are made of Permian chert. After knapping, the dart point was mounted to the dart fore shaft, and then thrown with an atlatl.
