Magma chamber processes over the past 475,000 years at Mount Hood, Oregon : insights from crystal zoning and crystal size distribution studies

Creator:: Darr, Cristina M.
Abstract:: Several different petrological techniques have been applied to lava flows between 200 to 475,000 years old from Mount Hood, Oregon. Mount Hood is unusual, in comparison to nearby Mount St. Helens and Mount Jefferson, in that it has produced relatively homogeneous lava compositions over 475,000 years. Erupted lavas are mostly...

Present-day and future contributions of glacier melt to the Upper Middle Fork Hood River : implications for water management

Creator:: Phillippe, Jeff
Abstract:: Glaciers are effective reservoirs because they moderate variations in runoff and supply reliable flow during drought periods. Thus, there needs to be a clear understanding of the influence of glacier runoff at both the basin and catchment scale. The objectives of this study were to quantify the late summer contributions...

3D vs. conventional volcanic hazard maps : a user study at Mount Hood

Creator:: Preppernau, Charles A.
Abstract:: Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...

The changing glaciers of Mt. Hood, Oregon and Mt. Rainier, Washington : implications for periglacial debris flows

Creator:: Ellinger, Jonathan R.
Abstract:: Mountain glaciers are receding worldwide with numerous consequences including changing hydrology and geomorphology. This study focuses on changes in glacier area on Mt. Hood, Oregon and Mt. Rainier, Washington where damaging debris flows have occurred in glaciated basins. Landsat imagery is used to map debris-free ice on a decadal time...

Meteorological conditions associated with rain-related periglacial debris flows on Mount Hood, Oregon and Mount Rainier, Washington

Creator:: Parker, Lauren E.
Abstract:: In November of 2006 an intense rainstorm of tropical origin, known colloquially as the "Pineapple Express," inundated the Pacific Northwest region of the United States, initiating numerous periglacial debris flows on several of the stratovolcanoes in the Cascade Range of Oregon and Washington. These debris flows rapidly aggrade channels, deposit...

Current and future economic impact of Mount Hood National Forest outdoor recreation consumption

Creator:: Anderson, David M. (David Matthew), 1964-
Abstract:: Mount Hood National Forest provides opportunities for many forms of outdoor recreation. Recreationists spend money to pursue outdoor activities on public lands such as national forests and national parks. The purpose of this study was to measure the economic contribution of national forest visitor expenditures on the local economy of...

Big huckleberry (Vaccinium membranaceum Dougl.) ecology and forest succession, Mt. Hood National Forest and Warm Springs Indian Reservation, Oregon

Creator:: Anzinger, Dawn
Abstract:: This thesis is an observational study that examines relationships between disturbance, forest stand development, and big huckleberry (Vaccinium membranaceum) fruit productivity and growth by combining ecological methods with the traditional ecological knowledge of Warm Springs ceremonial huckleberry pickers. Shrub fields of fruiting big huckleberry develop in early seral subalpine environments...
