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...

Mount Mazama and Crater Lake : A Study of the Botanical and Human Responses to a Geologic Event

Creator:: Green, Robyn A.
Abstract:: Crater Lake, located in the southern Cascade mountains of Oregon, is the seventh deepest lake in the world. Unlike a majority of the deepest lakes in the world, found in continental rift valleys, Crater Lake is in the caldera of a volcano. For the young at heart and mind, those...

The horizontal distribution and vertical migrations of the limnetic zooplankton in Crater Lake, Oregon

Creator:: Hoffman, F. Owen
Abstract:: During the summers of 1967 and 1968 the horizontal distribution and did vertical migrations of zooplankton were studied within the unique environment of Crater Lake. Sampling of the horizontal distribution was done by towing plankton nets vertically in different locations. The vertical distribution was sampled by towing at different depths...

The species composition, density, and distribution of the littoral zooplankton assemblage in Crater Lake, Oregon

Creator:: Warncke, William Madara
Abstract:: The species compositions and densities of the littoral and pelagic zooplankton assemblages in Crater Lake were compared. The littoral and pelagic zooplankton assemblages of most lakes are typically different due to different habitat conditions in the two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...

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...
