Class III Archaeological Survey Report: Madison Buffalo Jump State Park, Gallatin County, Montana

Through a cooperative agreement between the University of Montana (UM) Department of Anthropology and Montana Fish, Wildlife, and Parks, the University of Montana, between 17 May and 1 June 2014, conducted an archaeological inventory of the 640-acre Madison Buffalo Jump State Park. Douglas Macdonald, Ph.D. and Sara Scott, Ph.D. managed the project for each institution, respectively. Copious amounts of artifacts and features alike were recorded at Madison Buffalo Jump during the survey, including: 1) 3-4 drive lines used in the funneling of bison to jump locations; 2) bison bone concentrations below the kill/nick point on the face of the jump; 3) bone and artifact concentrations in the camp area in the creek valley west of the jump; 4) numerous lithic artifact concentrations within the gathering basin above the jump, marking the locations of prehistoric stone tool manufacture, including one possible petrified wood/chert quarry; 5) 78 stone circles in four locations surrounding the jump; 6) two probable fasting beds on a ridgetop north of the jump; 7) an Early Archaic projectile point produced from dacite sourced to the Cashman Quarry; 8) 14 additional sourced obsidian/dacite artifacts; 9) one bison bone fragment that confirms at Late Prehistoric age of the bison processing area (the only radiocarbon date yet assessed for the site); and 10) four locations of historic/modern inscriptions across the state park. Along with an overview of the current known prehistory/history of Madison Buffalo Jump, this report includes comprehensive details, maps, and descriptions of the archaeological artifacts and features that were recorded by UM during survey of the Madison Buffalo Jump

Ion Bombardment of Polyimide Films

Surface modification techniques such as wet chemical etching, oxidizing flames, and plasma treatments (inert ion sputtering and reactive ion etching) have been used to change the surface chemistry of polymers and improve adhesion. With an increase in the use of polyimides for microelectronic applications, the technique of ion sputtering to enhance polymer‐to‐metal adhesion is receiving increased attention. For this study, the argon‐ion bombardment surfaces of pyromellitic dianhydride and oxydianiline (PMDA–ODA) and biphenyl tetracarboxylic dianhydride and phenylene diamine (BPDA–PDA) polyimide films were characterized with x‐ray photoelectron spectroscopy (XPS) as a function of ion dose. Graphite and high‐density polyethylene were also examined by XPS for comparison of C 1s peak width and binding‐energy assignments. Results indicate that at low ion doses the surface of the polyimide does not change chemically, although adsorbed species are eliminated. At higher doses the chemical composition is altered and is dramatically reflected in the C 1s spectra where graphiticlike structures become evident and the prominent carbonyl peak is reduced significantly. Both polyimides demonstrate similar chemical changes after heavy ion bombardment. Atomic composition of PMDA–ODA and BPDA–PDA polymers are almost identical after heavy ion bombardment

Aluminum Deposition on Polyimides: The Effect of in situ Ion Bombardment

The chemistry of the Al polyimide interface is examined by x‐ray photoelectron spectroscopy sputter profiling. Al deposited on polyimide films without an in situ Ar backsputter shows a clearly defined 50‐Å Al2O3 layer just prior to the polyimide. This layer is identified by the O/Al atom ratio at 1.5, and the binding energy of the Al 2p transition. There is a clear separation of the Al/Al2O3/polyimide layers in the sputter profiles. Deposition of Al on polyimide surfaces after Argon backsputtering produces a diffuse Al/polyimide interface with no Al2O3 present. There is evidence in the Al 2p spectra for Al–C or Al–O–C type bonds, while the C 1s spectrum clearly has a metal carbide component. Increased adhesion of Al to polyimide surfaces with Ar backsputtering may be due to the differences in chemistry observed in these two instances
