The Office of the State Archaeologist recently posted a digital version of a new stone tool identification guide for Minnesota. The publication titled “Stone Tools of Minnesota” was authored by Toby A. Morrow with contributions by Scott F. Anfinson, Kent E. Bakken, Guy E. Gibbon, Michael D. Giller, John H. Hahn, Daniel K. Higginbottom, and Craig M. Johnson. The project was funded by the Arts and Cultural Heritage Fund of the Minnesota Clean Water, Land, and Legacy Amendment as part of the Statewide Survey of Historical and Archaeological Sites.
The book is more than just and identification guide to Minnesota’s stone tools, but a textbook on lithic materials and lithic technology in Minnesota. For example, the introductory chapter includes sections on; objects commonly mistaken for stone tools, facts about fakes (modern reproductions), how we have learned about stone tools, and lithic use wear and residue studies (plant residues including starches and phytoliths and animal residues like blood).
Besides the Introduction, chapters include; A Brief Primer in Geology; History of Lithic Analysis in Minnesota (Anfinson); Chipped Stone Tools; Projectile Points; Chipped Stone Raw Materials (Bakken); Ground Stone Tools; and a chapter on Future Directions which suggests the directions future studies to understand and analyze stone tools should take.
The book is heavily illustrated with excellent color photographs showing the artifacts full size and is over 400 pages in length. It has something for both the avocational and professional archaeologist. Due to the size of the digital file it was posted as two downloads. Part 1: http://mn.gov/admin/assets/stone-tools-of-minnesota-part1_tcm36-247478.pdf (14MB) and Part 2: http://mn.gov/admin/assets/stone-tools-of-minnesota-part2_tcm36-247479.pdf (17MB). At this time there are no hard copies of the report available, the Board of the Statewide Survey of Historical and Archaeological Sites is working on getting it published.
