Lithofacies, stratiography, and geology of the middle eocene type cowlitz formation and associated volcanic and sedimentary units, Eastern Willapa Hills, southwest Washington

Creator:: Payne, Charles William
Abstract:: Stratigraphic measurement of the 1,238-rn thick Cowlitz Formation in the southwest Washington type section along Olequa and Stillwater creeks reveals complex facies succession of wave- to tide-dominated deltaic sequences. The underlying, 625-rn thick upper member of the McIntosh Formation (as mapped by Wells, 1981) is composed of two units: a...

Sequence stratigraphy and lithofacies of the middle Eocene upper McIntosh and Cowlitz Formations, geology of the Grays River Volcanics, Castle Rock - Germany Creek area, southwest Washington

Creator:: Kleibacker, Derik W.
Abstract:: A composite 732-rn thick section in Germany Creek of middle Eocene upper McIntosh and lower Cowlitz Formations, as well as the lower Grays River Volcanics, was studied using bio-, magneto- and lithostratigraphy to construct a sequence stratigraphic framework and assess hydrocarbon exploration potential. The upper McIntosh Formation forms a complete...

Geology of the middle and upper Eocene McIntosh Formation and adjacent volcanic and sedimentary rock units, Willapa Hills, Pacific County, southwest Washington

Creator:: Moothart, Steve Rene'
Abstract:: The early to middle Eocene submarine basalts of the Crescent Formation form the core and basement of the structurally uplifted Willapa Hills region of southwest Washington. The formation consists of a thick sequence of predominantly subalkaline, tholeiitic pillow basalts and breccias formed as oceanic crust and seamounts at a sea...

Tourism and community perceptions : an examination of Mount St. Helens' tourism as perceived by local residents

Creator:: Baker, Randal G.
Abstract:: Since the eruption of Mount St. Helens on May 18,1980, the rural communities within its shadow have experienced tremendous change. Tourism has become a highly visible and somewhat controversial component of change in the region, and its importance to local economies has increased. As a result of increased tourism development...

Meeting of the magmas : the evolutionary history of the Kalama Eruptive Period, Mount St. Helens, Washington

Creator:: Lieuallen, Athena Erin
Abstract:: Comprehension of eruptive histories is critical in understanding the evolution of magmatic systems at arc volcanoes and may supply evidence to the petrogenesis of intermediate and evolved magmas. Within the 300 ka eruptive history of Mount St. Helens, Washington, the Kalama Eruptive Period, 1479- ~1750 CE was bracketed by interludes...

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...

Soil erosion and vegetation loss accelerated by visitor use of Paradise Meadows, Mount Rainier National Park

Creator:: Fritzke, Susan L.
Abstract:: Recreational impacts on the subalpine-alpine ecosystems of Mount Rainier National Park have developed over the past century, and today pose a major problem for park managers. Field data were collected during the summer of 1987 in the Paradise meadows area in order to describe visitor impacts on social trails (trails...

Active deformation of the Cascadia forearc : implications for great earthquake potential in Oregon and Washington

Creator:: Goldfinger, Chris
Abstract:: Nine west-northwest-trending faults on the continental margin of Oregon and Washington, between 43° 05'N and 470 20'N latitude, have been mapped using seismic reflection, sidescan sonar, submersibles, and swath bathymetry. Five of these oblique faults are found on both the Juan de Fuca and North American plates, and offset abyssal...

Stratigraphy and sedimentology of the middle eocene Cowlitz Formation and adjacent sedimentary and volcanic units in the Longview-Kelso area, southwest Washington

Creator:: McCutcheon, Mark S.
Abstract:: Geologic mapping of the Longview-Kelso area and the measurement and description of a composite 650-meter thick stratigraphic section of the Cowlitz Formation (Tc) in Coal Creek using bio-, magneto-, litho-, and sequence stratigraphy reveals a complex interplay of Cowlitz micaceous, lithic arkosic shelf to tidal/estuarine to delta plain facies associations,...
