Geomorphic Mapping • Based on Lidar topography, NRCS soils map, and field stratigraphy • Active floodplain – Lowest prominent surface – Has common abandoned meanders, scroll bars, etc. – Correlates with soils containing Mazama tephra (ca. yr BP) • Terraces, tributary fans, etc. – Based on topography, soils, field checking. It is at or near the surface from northern Nassau County southward to Highlands County forming the peninsular highlands. and the late Pleistocene Fort Thompson Formation. This section consists of fossiliferous sands and carbonates. Willamette Silt (Allison, ; Wells and Peck, ), alluvial silt, sand, and gravel that form terrace.

Overlies eroded surface [Coriba Surface] of Columbia River basalt but mostly overlies Dalles formation in Columbia Gorge area. Underlies Cascan formation (new) and underlies and is intruded by andesitic lavas. Is similar in age to post-Shutler gravel stage of ancestral Columbia River, thus probably earliest Pleistocene(?) age.

The morphology and genesis of soils of the Willamette series and of some Willamette-associated soils and their relationships to geomorphic surfaces were studied in an area near McCoy, Polk County, Oregon. Influences of regional extent, such as climate and parent material, were related to the soils Cited by: 1.
Graduation date: The morphology and genesis of soils of the Willamette series\ud and of some Willamette-associated soils and their relationships to\ud geomorphic surfaces were studied in an area near McCoy, Polk\ud Willamette and associated soils on late Pleistocene geomorphic surfaces, Oregon.
Influences of regional extent, such as climate and\ud parent material, were related to the Oregon book and landforms. Argixerolls in the Yamhill Valley in Polk County, Oregon, have characteristics that are determined by the age, topography, and parent materials of three late Pleistocene geomorphic surfaces.
The newly defined Bethel surface is in the highest topographic position. Independent records of Willamette Valley flora for the late Pleistocene are insufficient to reconstruct the proportion of C 3 and C 4 plants, but a C 3 diet would be consistent with the MacFadden et al.
() finding that Pleistocene herbivores at latitudes above 45° (which is approximately the southernmost latitude of the sampled Willamette Valley animals) almost exclusively consumed C 3 by: 7. Witzel* soils are commonly found on buttes and other steep, active (5) slopes in the Willamette Valley.
Witzel* soils have dark brown and dark reddish brown, gravelly silty clay loam A and B horizons which over- lie, at depths of 15 to 20 inches, a IIR horizon (15) composed of fractured basalt bedrock. Low soil pH is found in thick middle Pleistocene soils of bedrock (Jory, Willakenzie, Laurelwood, and Bellpine soil series) and high soil pH in thin soils on late Pleistocene and Holocene Missoula.

O‟Connor Portland State University © WILLAMETTE AND ASSOCIATED SOILS ON LATE PLEISTOCENE GEOMORPHIC SURFACES POLK COUNTY, OREGON INTRODUCTION "Soils of the Willamette series occupy the gently rolling, naturally drained, brown-colored lands in the old Valleyfilling or Valley floor of the Willamette River and include about one-third mil.
However, a few of the workers returned some of the bones to the city where Dr. William Orr of the University of Oregon identified the bones as late Pleistocene mammals.
These include: bison, giant ground sloth, sheep and horse. Some of these bones are now on display at Woodburn Public Library.
Woodburn Public Libary. It drains oversquare miles in the Pacific NW and over 50% of Oregon. Its impact on the cultures of Oregon looms large. The Columbia is also the location of the greatest floods to ever occur on the earth.
During the Pleistocene, so much water was tied up in glaciers and snow, that sea levels were more than feet below those of today. ABSTRACT. Stratigraphic and chronologic information collected for Quaternary deposits in the Willamette Valley, Oregon, provides a revised stratigraphic framework that serves as a basis for a ,scale map, as well as for thickness estimates of widespread Quaternary geologic units.
Polk County Natural Hazards Mitigation Plan: Expansive Soils Page Why are Expansive Soils a Threat to Polk County. Soil is an essential component in the construction and stability of houses, commercial buildings, and other structures.
Since structures are built on soil. Peacock larkspur is a localized endemic restricted to the middle Willamette Valley of Oregon.
The species is found primarily within Benton and Polk counties, its largest occurrences located at William L. Finley National Wildlife Refuge in Benton County.

Sediments at the southern summit of Hydrate Ridge display two distinct modes of gas hydrate occurrence. The dominant mode is associated with active venting of gas exsolved from the accretionary prism and leads to high concentrations (15%–40% of.
Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
Because numbers are hard to remember, and names are easy to recall, most major excavations, as noted, add a site "name," thus LK-1 is "Fort Rock Cave.
