Scenic quality at Crater Lake National Park : vistitor perceptions of natural and human influence

Creator:: Rolloff, David B.
Abstract:: This study explored park visitors' preferences for scenic vistas at Crater Lake National Park, and whether their scenic evaluations would be affected if water levels of Crater Lake changed. Three main areas were addressed in the study. The first tested park visitors' ability to perceive differences in the level of...

A new model for the formation of Crater Lake Caldera, Oregon

Creator:: Lidstrom, John Walter
Abstract:: During the Pleistocene, an andesitic volcano named Mount Mazama grew to a probable elevation of 3000 meters in south- central Oregon. Near the end of the Pleistocene, three diverse magma types appeared in the eruptive products associated with Mount Mazama: l)High-alumina basaltic andesite magma associated with an early plateau and...

An investigation into the comparative utility of color infrared aerial photography and LANDSAT data for detailed surface cover type mapping within Crater Lake National Park, Oregon

Creator:: Walsh, Stephen Joseph, 1951-
Abstract:: The identification and mapping of surface cover types within Crater Lake National Park, Oregon, has been effectively completed through the utilization of LANDSAT digital data and NASA U-2 color infrared aerial photography. Classification of LANDSAT data for surface cover type identification and mapping was accomplished through use of the Interactive...

An investigation into modeling snow cover elements at Crater Lake National Park and surrounding environs as an improved "ground truth" method for satellite snow observations

Creator:: Hamilton, William L.
Abstract:: Streamflow forecasts are essential to the optimal operation of hydroelectric and irrigation reservoirs in the Pacific Northwest. Satellite snow cover observations would aid in these streamflow forecasts by providing snow cover data at regular time intervals. Unfortunately, satellite capability to remotely sense mountain snow cover conditions is indeterminate due to...

The effects of natural fire and recreational disturbance on montane forest ecosystem composition, structure and nitrogen dynamics, Crater Lake National Park, Oregon

Creator:: Wilson, John K. (John Kevin)
Abstract:: Disturbance, whether natural or of human origin, modifies to varying degrees many ecosystem attributes. Fire is a natural process in the montane forests of southern Oregon but for much of the 20th century fire was viewed as an apocalypse and thus fervently suppressed. Effective natural resource management requires an understanding...

Effects of disturbance modes on mycorrhizal fungus communities at Crater Lake National Park

Creator:: Trappe, Matt
Abstract:: Crater Lake National Park presents an excellent opportunity for ecological research due to its relatively pristine landscape, the protection of its natural features, its infrastructure, and a Park administration supportive of scientific inquiry and restoration ecology. The research presented here examines the responses of fungi to various forms of perturbation....

Vitamin B₁₂ production and depletion in a naturally eutrophic lake

Creator:: Gillespie, P. A.
Abstract:: The vitamin B₁₂ concentrations in both the water and sediments of Klamath Lake were found to vary significantly during a one-year period. The patterns of B₁₂ distribution were remarkably similar among the three main sites. In all cases there was an extremely sharp gradation in concentration in relation to depth...

N fertilizer effects on soil solution Mn and Mn response of barley and oats

Creator:: Petrie, S. E.
Abstract:: A series of field experiments was established in 1978, 1979, and 1980 on Lower Klamath Lake where Mn deficiency of oats had been observed in previous years. The pH of the soils ranged from 7.6 to 8.3 and the organic matter content was between 17 and 19%. The objectives of...
