The archaeological resources contained in Corvallis Riverfront Commemorative Park (RCP) have a great potential to add to the historical record of the warehouse district of the original town of Marysville (Corvallis). The City of Corvallis' proposed Combined Sewer Overflow (CSO) project and proposed changes to Riverfront Commemorative Park threaten to destroy archaeological resources within the research area. The purpose of this research was to assess the archaeological potential of the research area between VanBuren and Jefferson Avenues along the Willamette River. The assessment was based on an archaeological survey and historical documents. Historical records and maps were used to create a chronology of the developments which occurred within the research area. By knowing who occupied the riverfront and when, archaeologists can design a plan for the excavation of these resources. The archaeological survey was conducted to locate remains that may be related to structures that once occupied the riverfront. Maps of the City's proposed construction were used to determine the potential resources that will be impacted. The historical record indicated that there is a great potential for the research area to yield archaeological remains which can add to our knowledge about the formation of Marysville (Corvallis). These archaeological remains if properly excavated could be used for public interpretation and as a common theme within Riverfront Commemorative Park. An assessment of construction project maps for the CSO project and proposed changes to Riverfront Commemorative Park indicate that a majority of the archaeological resources contained within the research area will be destroyed. Based on these assessments it is recommended that the City of Corvallis conduct subsurface archaeological testing to recover as much information related to the settlement of the research area as possible. / Graduation date: 1998

The Quartz Mountain Obsidian Quarry is located in the Southeast corner of the Bend Fort Rock Ranger District in central Oregon, approximately forty-five miles southeast of Bend, Oregon. The research of the Quartz Mountain Obsidian Quarry began with a literature search of other quarry sites in the area and the use of aerial photos to determine the survey area. After the survey area was established a ground survey was conducted. Following the survey several key areas were chosen for surface collections that could answer key questions: What types of core reductions were being used on Quartz Mountain?; and What types of materials were being utilized? (red/black obsidian found in rhyolite veins, red/black obsidian found in fist sized and larger nodule form, or large block black obsidian). In order to answer these questions three collection units were established. The lithic material from the units was collected and analyzed and the information placed into a database, which was then grouped for statistical analysis, and generated into charts and tables. The resulting data was then compared to the information found from an extensive literature search to see how the material that I collected compared to those found at other quarry sites. From this information I was able to determine that two different core reduction methods were being used on Quartz Mountain: blade core and bifacial core. Along with the different core reduction methods a mobility strategy also came into play. In this thesis I will use the data gathered to determine the different core reduction methods and the mobility strategies that are associated with them. / Graduation date: 1998

This study explores private and public campground markets in Oregon. A profile of private and public campgrounds, their prices, location, and amenities, served as the supply side statistics while responses from the 1997 Campground Questionnaire provided data for demand of Oregon campgrounds. The questionnaire inquired about respondents' last camping trip in Oregon, where they camped, how much they paid, the facilities available, the activities in which they participated, socioeconomic attributes, and included a dichotomous choice contingent valuation (CV) question. These data were used to statistically analyze differences in the supply and demand for the private and public campground sectors. First, the inventory was examined using OLS to estimate the effects of campground amenities and location on user fees charged at different campsite types at private, federal, and state campgrounds. Second, I used the survey data (i.e., respondent profiles and campground attributes) to estimate substitution probabilities among campsite type and campground ownership using a nonlinear multinomial logit model. Questionnaire information was also utilized to test for market segmentation and identify the user groups' characteristics. Finally, I utilized responses to the CV question to determine the amount of consumer surplus for Oregon state parks. The significant inventory results were as follows. The model predicted that tent sites at state campgrounds are more expensive, on average than tent sites at private campgrounds. National Forest campgrounds located in eastern Oregon, on average, are less expensive than those at private and state campgrounds. The survey statistical results predicted that users of tent sites appear to be the least price sensitive, for both private and public markets. Recreational vehicle owners are more price sensitive than tent owners in both the private and public markets. Furthermore, those campers that choose a full hookup site are the most likely to use the OPRD reservation system. The contingent valuation data revealed, through linear regression, that campers would be willing to pay $44.71 more than they currently pay for a camping trip if the payment were used to improve and maintain state parks. This research is intended to contribute statistical reference for user fees and general market information to the Oregon Parks and Recreation Department. / Graduation date: 1999
