About Mammoth Run

My family and I have been collecting artifacts on the high plains for over 50 years. Recently we’ve become interested in producing high quality casts of high plains artifacts for study and enjoyment. Many of our customers are Universities and they use these casts as study tools with their students. Knappers and collectors will also enjoy these replica casts.

As you will note in our store, many of our casts are pictured in aggregate groups. These casts are all available individually as well. We also create high quality molds of individual artifacts upon request. If you are interested in having an artifact in your collection cast, please send a picture of the artifact(s) and we will provide you a basic cost for the mold and two casts.

Also, please check out our extensive data base. Although we don’t have them pictured, we have over 750 casts available. If you see something you are interested in having us cast for you, please let us know. If you have any questions, please don’t hesitate to contact us.
