Mammoth Run Lithic Casting, per their website, "provides high quality lithic casts of high plains artifacts along with artifacts from other regions of the country. They have an inventory of over 850 molds that include points from many important sites including: Agate Basin, Casper, Fenn cache, Finley, Horner, Hudsen-Meng, Blackwater Draw, Colby, Lindenmeier, Westfall, Hawkins, Scoggins, Medicine Lodge Creek and others. They also have a number of Folsom and Clovis casts available of points that were found in and along the South Platte River and other areas of eastern Colorado, western Nebraska and Wyoming." Their rates are reasonable, product quality is excellent, and leaving the real artifacts behind at a location to be professionally studied is the best way to preserve these non-renewable resources for future generations and visitors.
