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...

Controls on eruption style and magma compositions at Mount Hood, Oregon

Creator:: Koleszar, Alison M.
Abstract:: This study is an effort to characterize the magma sources, plumbing system, and eruptive behavior of Mount Hood, a low-explosivity recharge-dominated volcano in the Oregon Cascades. The three manuscripts in this dissertation make use of melt inclusion data, phenocryst compositions, and whole rock petrology and geochemistry to build a schematic...

Vegetation classification for the badger allotment, Mt. Hood National Forest

Creator:: Williams, Clinton K.
Abstract:: More than 200 sites between 500 and 2000 meters elevation were examined utilizing a reconnaissance sampling technique for a portion of the eastern slopes of the northern Oregon Cascade Mountains. Twelve different forested plant communities were described with data on vegetation, soils and topography. A map of their distribution and...

Historical landscape reconstruction and perceptual geography of Mount Hood, Oregon

Creator:: Belgam, Daniel R.
Abstract:: This research seeks to understand the influences of perception on land use around the Mount Hood area of Oregon and evaluate how it has evolved over the past 4,000 years. The study addresses three specific questions: 1) How has the study area evolved over time into the modern landscape? 2)...

Early seral plant communities: pacific silver fir zone Mt. Hood National Forest

Creator:: White, James D., Haglund, John C., Mellin, T. Kim, and United States. Forest Service. Pacific Northwest Region
Abstract:: This guide is intended to assist Forest personnel in managing early seral stands within the Pacific Silver Fir Zone of the Mt. Hood National Forest, by providing descriptions of early seral plant communities, linking them (when possible) to Mt. Hood National Forest Plant associations, and identifying some management considerations. As...

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...
