Thoms (database editor) Publication_Date: 2003 Title: Maps Showing Inundation Depths, Ice-Rafted Erratics, and Sedimentary Facies of Late Pleistocene Missoula Flood in the Willamette Valley, Oregon Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: Open-File Report Issue_Identification: OF 03-408 Publication_Information: Publication_Place: Menlo Park, CA Publisher: U.S. Geological Survey Description: Abstract: This digital dataset, compiled from previously published and unpublished data sources, contains a personal geodatabase and raster data of features related to the repeated inundation of the Willamette Valley and Portland basin by Missoula Flood waters in Late Pleistocene time. The feature classes contained within the Will_Valley geodatabase are called 'erratics', representing the locations of ice-rafted erratics; 'contours', representing inundation levels associated with stratigraphic evidence of repeated floodings; and 'geology', representing the general distribution of Missoula Flood deposits. A stand-alone table within the geodatabase contains geologic unit descriptions for the geology polygons contained in the 'geology' feature class. 7 ESRI format raster grids are also included in this dataset that illustrate the physiography of the Willamette Valley as well as 4 important inundation levels. The scale of the source maps limits the spatial resolution (scale) of the database to 1:250,000 or smaller. Purpose: Most significantly, this database represents the most comprehensive compilation of Willamette Valley and Portland basin glacial erratic data to date. 400 records are contained herein, representing work from the 1920's to the present.

Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:250,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:250,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

Features were imported from various digital sources and digitized from paper sources. Base elevation, shaded-relief, and hydrography grids were copied from previously generated grids. Flood inundation level grids were extracted from the elevation grid. Contour lines of 4 significant inundation elevations were generated from the elevation grid with the Spatial Analyst extension to ArcGIS 8.3.
