One taphonomic problem plaguing archaeologists and physical anthropologists, whether their research is in North American cultures or hominid sites in Africa, is the difficulty in distinguishing bone altered by burning and heating from bone altered by soil processes. Archaeologists working to understand the recent prehistory of the Southern Oregon Coast face the same challenge. Two relatively new tools were investigated to determine their usefulness to resolving this problem. These are scanning electron microscopy (SEM) and X-ray diffraction (XRD). SEM has been well-tested in African sites and experimental studies to identify hominid-created cut marks on bone and to reconstruct heating temperatures of burnt bone. However, SEM and its ability to sample chemistry, as well as XRD's ability to detect diagentic alteration in bone minerals, have not been tested on material from coastal Oregon. The purpose of this research was: (1) to test these methods to see whether they could distinguish between burning and soil alteration, using cervid bone from site 35CS43 near Bandon, Ore., as a test sample, and (2) to see whether the result, paired with archaeological, ethnographic, taphonomic and faunal evidence, could be used to understand how the Coquille were procuring, processing and cooking cervids as insights into their adaptation. The outcome suggests that SEM and XRD, without use of other evidence, are unable to distinguish between burning and soil alteration because the similarities between the two lie not only in changes to the bone's macrostructure (discoloration) but also in bone chemistry, where it was hoped differences could be found. However, these techniques, when paired with the other lines of evidence, did provide insights in understanding the taphonomy and the Coquille's use of cervids - the interaction of bone and soil; the extent of mimicry between burning and soil alteration; and ultimately that discoloration of cervid bone at 35CS43 was likely due to soil alteration, that burning as the result of fire roasting was most likely not occurring at the site, and that the Coquille employed other methods of cooking. / Graduation date: 2003

A print copy of this title is available through the UO Libraries under the call number: KNIGHT E78.O6 E53 1994 / A major concern of Columbia Plateau archaeology has been the development of the ethnographic "Plateau pattern." Observed during historic times, this lifeway focused on permanent riverine winter villages and intensive use of anadromous fish, with ephemeral use of interior tributaries and uplands for hunting and root gathering. Constrained by a salvage-driven orientation, past archaeological research on the Plateau has been biased towards major rivers, leaving aboriginal lifeways in the interior to be interpreted on the basis of ethnographic analogy, rather than archaeological evidence. The present study utilizes museum collections from the Pine Creek basin, a small tributary of the John Day River, to provide information on prehistoric lifeways in a non-riverine Plateau setting. Cultural assemblages and features from two sites, 35WH7 and 35WH14, were described, classified, and analyzed with regard to temporal distribution, spatial and functional patterning, and regional ties. At 35WH14, evidence of semisubterranean pithouses containing a rich and diverse cultural assemblage suggests long-term and repeated residential occupation of this site by about 2600 B.P. This contrasts with the ephemeral use predicted for the area by ethnographic accounts. Faunal remains identified from 35WH7 and 35WH14 show a persistent emphasis on deer, and little evidence for use of fish; this non-riverine economic base represents a further departure from the ethnographic "Plateau pattern." At both 35WH14 and 35WH7, large pithouses are not evident in components dating after 900 B.P., reflecting a shift to shorter sojourns at these sites. Use of the Study Area as a whole persists, however, and is marked by a proliferation of radiocarbon-dated occupations between 630 and 300 B.P. Clustering of radiocarbon dates from ten sites in the Study Area shows correlations with regional environmental changes. Both taphonomic and cultural factors are discussed. Reduced human use of the area after 300 B.P. is reflected in an abrupt decline in radiocarbon-dated occupations and the near-absence of Euroamerican trade goods. The role of precontact introduced epidemics is considered. Further consideration of spatial and temporal variability in Late Archaic Plateau prehistory is urged. / Committee in charge: Dr. C.
