The construction of Illinois Falls fish ladder on the Illinois River in Oregon was completed in November 1961. The ladder was opened and operated during the winter of 1961-62. Final cleanup and rock removal was completed in the fall of 1962. The ladder was installed on a natural barrier where...
The purpose of this study was to develope a plant community classification
within the Siskiyou mountains, a small range within the Klamath
geological province well known for its geologic and floristic diversity.
Forest land managers have expressed the need for identification of
basic Land classes that will aid in the...
This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...
Approximately 5,500 years ago a discreet period of
wetter and cooler environmental conditions prevailed
across the southern Columbia Plateau. This period was
marked by the first prominent episodes of erosion to occur
along the lower Snake River following the height of the
Altithermal and eruption of Mt. Mazama during the...
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...
The variability of selected physical, chemical, and morphological
soil properties in two landtype mapping units on'the Rogue River National
Forest in southwestern Oregon was studied.
The objectives of the study were (i) to quantify soil variability
in several soil resource inventory mapping units, (ii) to explore methods
of describing soil...
A ground-breaking study of the relations between the fur traders of Fort Nez Perce's and the Indians of the region, primarily Cayuse, Wallawalla, Umatilla, and Nez Perce. Existing literature on this region has focused on the white explorers, the fur traders, and the settlers; Chiefs and Chief Traders offers a...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
This study is a synthesis of the available ethnographic and relevant archaeological data pertaining to the Native American groups who formerly occupied the upper Rogue River drainage of southwestern Oregon. The information presented in this synthesis concerns the material, social and religious aspects of aboriginal life as practiced by the...
The following outline of events in the rise and fall of gold mining in southwestern
Oregon is here recorded - almost as an obituary - so that Oregonians may not entirely forget how important this industry was in building up this part of the state.
Several changes appear to be needed in present disposal practices.
Usable materials are discarded in our society in large volume and many of these substances are nonreplaceable minerals. Not only are the minerals themselves lost to society but the energy which produced them is lost as well. Also, the current...
Peakflow frequency analysis is used in forest hydrology for designing stream crossing structures such as culverts and bridges. The traditional approach to frequency analysis is based on the assumption that the observed sample of peakflows represents a homogeneous population. It is not clear if using the "homogeneous" population of the...
Average annual losses caused by geologic hazards in Oregon are difficult to determine, owing to incomplete and scattered data. Preliminary considerations, however, indicate that losses to landslides may total between $4 million and $40 million per year. As many as nine persons have been killed by one landslide in Oregon...
This is the second and concluding volume in Stern's acclaimed study of the relationships between Plateau Indians and the white fur traders, missionaries, and settlers who entered their world.
Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...
A diversity in climate, geologic parent material, and soil
characteristics exist in Jackson, Josephine, Coos, and Douglas
Counties of southwest Oregon. Previous field trials and soil testing
results have revealed uncertainties as to the phosphorus (P) status
of the soils in this area. Twenty-four sites from nine agriculturally
significant soil...
Phacelia capitata Rruckeberg is a member of the
Phacelia magellanica polyploid complex (species group
Magellanicae), a group of wide-ranging, polymorphic
perennials in western North America related to the South
American P. secunda (= P. magellanica). The purpose of
this project was to determine, to the extent possible, the
interrelationships of...
In the past, archaeological investigations have recovered material culture that have often been stored as museum property without a focused analysis or written report of the results. This study focuses on one such assemblage ofchipped stone projectile points from the Bachman Cave locality of southwestern Idaho that has been stored...
The objective of this paper is to conduct a geographical inventory
of a sand and gravel site, Lower Kiger Island, so as to identify and
evaluate other potential land uses subsequent to the extraction of its aggregate
resources. This information is intended to aid citizens, land use
planners, and sand...
Recommendations are provided in this watershed analysis to identify actions and management decisions on the part of BLM that might improve watershed health in the Trask River watershed.
As Europeans settled the Willamette Valley in the 1800s, they began to simplify Oregon's largest river contained wholly within state boarders—the Willamette. The river lost miles of channels from dikes, dams, and development. Some channels vanished under concrete. Others became meander scars, or shallow, dry depression in the land where...
Archival information about fish and water in the Umpqua Basin can be found in reports housed in disparate locations (e.g., offices of various State and Federal agencies and local organizations). A comprehensive bibliography of grey literature, important or uncataloged reports, and published reports is one means of recording what research...
The platinum-group metals have been the subject of considerable discussion in the news media over the past few months, particularly because of their projected use as catalysts in automobile engines. Metals Week of August 27 shows that platinum commands a price of $176.00 per ounce, as compared to $150.00 per...
The United States has enormous deposits of oil shale which, if developed, could provide energy resources for centuries. Because of the vast size of these deposits, they are currently receiving a great deal of attention. This issue of The ORE BIN is devoted to a discussion of oil shale --...
