Data from the southern Cascade Mountains of
Oregon has been collected for application in computer
analysis of snowfields. Vegetation type, canopy
cover, slope, aspect, insolation, and snowfield
ground truth delineation are given consideration.
In addition, a procedure for transferral of data
onto Landsat imagery was derived.

Fire, other disturbances, physical setting, weather, and climate shape the structure and function of forests throughout the Western United States. More than 80 years of fire research have shown that physical setting, fuels, and weather combine to determine wildfire intensity (the rate at which it consumes fuel) and severity (the...
Twenty-year-old Douglas-fir trees in provenances from Arizona,
New Mexico, and southern Colorado survived better and grew taller;
but incurred more winter injury in eastern Nebraska than trees from
provenances from northern Colorado, southern and western Montana,
northern Idaho, Canada, and eastern Washington. However, surviving
trees from Pacific Coast, and northern...
The Jefferson Mountain area, located at the eastern end of
the Centennial Mountains in Fremont County, Idaho and Beaverhead
County, Montana, is approximately 42 square miles in size. The
area contains exposed metamorphic, sedimentary, and volcanic
rocks ranging in age from Precambrian to Tertiary. Approximately
2,500 feet of Paleozoic and...
This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative invasive annual grasses and...
Six high-use destination areas were studied in the Alpine Lakes, Mount Jefferson, and Three Sisters Wildernesses in Washington and Oregon. Exit interviews were conducted with visitors, and recreation impacts and visitor encounter rates between groups were quantified. Encounter rates were extremely high and impacts were substantial but localized. Visitors were...
A primary focus of the US Global Ocean Ecosystem Dynamics
(GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale
climate forcing under the assumption that bottom-up forcing controls a large
fraction of marine ecosystem variability. At the beginning of GLOBEC, the prevailing
bottom-up forcing hypothesis was that...
The Peck Mountain area is located in west-central Idaho just 15 miles east of the Oregon-Idaho border. It is tectonically located within the "Columbia Arc" of the Nevadan oroaenic belt. The Seven Devils Volcanics, Permian to Traissic in age, are the oldest rocks in the area. They are composed of...
This thesis situates a discussion of Thoreau's later natural history essays in the context of the author's other writings. Beginning with an examination of the writings of Thoreau's friend and mentor Ralph Waldo Emerson, this paper examines Thoreau's relation to and departure from Emerson's understanding of time, place, and pattern...
My thesis explores the later work of author J.D. Salinger, including two narratives featured in Nine Stories, "A Perfect Day for Bananafish," and "Teddy," and Franny and Zooey, "Raise High the Roof Beam, Carpenters," and "Seymour: an Introduction." Through my analysis I argue that the religious nature of Salinger's fiction...

Tarif access tables were developed for mountain hemlock [Tsuga mertensiana (Bong.) Carr.] on the Deschutes National Forest in the Central Oregon Cascade Mountains from an equation for cubic-foot volume including top and stump (CVTS). These tables provide access to the comprehensive tree-volume tarif system.
The thesis area includes 44 square miles of the Centennial
Range in Beaverhead County, Montana, and Clark County, Idaho.
The rocks exposed in the area range in age from Precambrian
to Recent and have been divided into 23 mapped units. Pre-Belt
metamorphic basement rocks are overlain unconformably by 3,433
feet...
