The distribution of geologic and artifact obsidian from the Silver Lake/Sycan Marsh geochemical source group, South-Central Oregon

Creator:: Thatcher, Jennifer J.
Abstract:: Geochemical characterization methods are commonly used in the reconstruction of prehistoric raw material use and procurement systems. Trace element studies of lithic source material and artifacts, specifically those made of obsidian, can reveal important information about the environmental and cultural factors which influence the prehistoric distribution of raw material. The...

Upper Deschutes River Basin Prehistory: A Preliminary Examination of Flaked Stone Tools and Debitage

Creator:: Taggart, Michael W.
Abstract:: The prehistory of Central Oregon is explored through the examination of six archaeological sites and two isolated finds from the Upper Deschutes River Basin. Inquiry focuses on the land use, mobility, technological organization, and raw material procurement of the aboriginal inhabitants of the area. Archaeological data presented here are augmented...

The cultural significance of mountain regions : implications for the Calapooya Divide, Oregon

Creator:: Starr, Karen J.
Abstract:: Altitudinal variations in upland regions of the earth create variable climatic zones and conditions. Plant and animal communities must adapt to these conditions, and when they reach their tolerance limits for environmental conditions at the upper levels of a zone, they cease to exist in the environment. Humans also utilize...

Quantitative basin morphology and channel stability with reference to nonpoint sources of pollution in Evans Creek, Oregon

Creator:: Krupin, Paul J.
Abstract:: A Stream Reach Inventory and Channel Stability Evaluation procedure has been used to assess the nature and extent of erosional nonpoint sources of pollution in the Evans Creek basin, a tributary to the Rogue River, in southwestern Oregon. The study is based upon the results of the Oregon Department of...

Land trusts in the New West : conserving and responding to local geographies?

Creator:: Loynes, Kathryn
Abstract:: This research focuses on the relationship between the emerging role of land trusts and rapid growth and change in the West. Teton County, Idaho, Teton County, Wyoming, and Sublette County, Wyoming, and each of their associated land trusts, are used as case studies. Each county has experienced varying levels of...

Morphometric properties of nivation hollows on Hart Mountain, Lake County, Oregon

Creator:: Rademacher, Christopher L.
Abstract:: Hart Mountain is a basaltic fault block mountain in the semi-desert region of the northern Basin and Range province in south-central Oregon. Geomorphic processes associated with lingering snowpatches have formed nivation hollows, which are small scale depressions in the hillsides. The lingering snow in the hollows prohibits shrub growth. Bedrock...

Spatio-temporal patterns and trends in MODIS-retrieved radiative forcing by snow impurities over the Western U.S. from 2001 - 2022

Creator:: Jensen, Anna S.
Abstract:: Seasonal mountain snowpack of the western US (WUS) is a key water resource to millions of people. Impurities at the snow surface directly affect snowmelt timing and rate, as they contribute to earlier peak streamflow, snow disappearance, and less water availability in dry months. Predicting the locations, timing, and intensity...

Interacting effects of climate, forest dynamics, landforms, and river regulation on streamflow trends since 1950 : examples from the Willamette Basin and forested headwater sites in the US

Creator:: Hatcher, Kendra L.
Abstract:: Streamflow patterns are a result of the interaction of many factors, including climate, vegetation, geology, and topography. Analyses indicate that streamflow patterns have changed around the United States over the past century, raising questions about the possible role of climate variability as a driver of water yield. This thesis examines...

The historic and contemporary ecology of western Cascade meadows : archeology, vegetation, and macromoth ecology

Creator:: Highland, Steven A.
Abstract:: Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...

Spatial distribution and the probability of occurrence of beluga whales (Delphinapterus leucas) in Alaskan Arctic

Creator:: Romeo, Lucy F.
Abstract:: The known distribution of beluga whales ranges from sub-Arctic to Arctic waters where they migrate in pods in response to environmental factors such as the presence of sea ice and prey. This study uses bivariate and multivariate analysis techniques to measure how environmental covariates are associated with the spatial-temporal distribution...
