Title of ~hesis/~issertation: Southeastern Montana in the Late Prehistdric Period: Human Ada~tationand . Projectile Point Chronology Author : (signa tu rd3/ Lynn Berry Fredlund (name ) (date) ABSTRACT A central goal of this thesis is to provide a framework for explaining adaptive strategies and artifact histories of the Late Prehistoric Period I (A.D. 250-1000) and I1 (A.D. 1000-1700) in the Pine Breaks of southeast Montana. The method by which this is achieved involves the identification and clarification of the expanded flake point tradition through, in part, a survey of the literature and through the exploration of evidence from exca- vated sites and survey inventory sites, many of which are not yet fully pub1 ished. Present archaeological evidence suggests that hunting, lithic procure- ment, population density, and settlement systems of the Pine Breaks area were somewhat different from those of the open plains. The Pine Breaks, an ecologically distinct area within the Northwestern Plains, provides many attributes for human occupation that the open plains do not. The Period I Benson's Butte-Beehive complex represents an adaptation to the Pine Breaks. It is characterized by Avonlea-1 ike points, high fortifiable 1iving locations and circular rock-walled dwell ing structures. Benson's Butte, one of the type sites of this complex, also yielded evidence of a point manufacturing technique which utilizes a distinct expanding flake. It is hypothesized that use of the--- expanding_.fl&e forms the basis of the fabrication process for most of all Late Prehistoric small side-notched arrow points. Based on this manufacturing tradition, it follows that tri- angular unnotched forms or "points" are rarely used as projectile tips, but as preforms for the notched points of the Late Prehistoric period. Although identified in the Pine Breaks area, this refinement of projectile point ii i chronology is appl icable to the Northwestern Pl ains and possibly other areas of North America. ACKNOWLEDGEMENTS In the process of writing this dissertation I had suggestions and, more important, moral support from a great many people. Phil Hobler and nut Fladmark read the various drafts and provided me with thought-pro- voking ideas and much needed guidance. Phil put up with the long-distance phone calls, hassles with the mail strike and other minor crises to insure that everything was done in a timely and proper manner. The discussions and friendly arguments provided by Knut were a learning experience in themselves. The rest of the staff, particularly Roy Carlson, Earle Nelson and Jack Nance, were always will ing to talk and work out problems. Ingrid Bell and the office staff helped with bureauratic difficulties. Without the assistance and support of my family and the Mineral Re- search Center staff it would have been difficult to complete this work. 1 have had the use of the facilities and equipment and many people to discuss my ideas and theories. My husband, Dale, has been supportive, critical, and was the primary person who helped me work out the details of much of the following work. Dale Herbort, who is especially interested in lithic technology, worked with me by knapping various materials, trying various techniques and critically reviewing my commentary on manufacturing of tools. Susan Steere, Howard Billian, and Shirley Munson reviewed and proofed the drafts. Jerry Clark and David Fraley, BLM archaeologist, pro- vided very pertinent comments and suggestions. Margo Chapman helped me in too many ways to list here. Finally, Patsy White who helped type, compile the final draft and supply needed sparks of humor throughout deserves a special thanks.
