This publication updates previous fault maps of Oregon as a contribution to the larger U.S. Geological Survey effort to produce digital maps of active faults in the Pacific Northwest region. The new map is derived from the 1992 fault map of Pezzopane, Nakata, and Weldon that has seen wide distribution and has been reproduced in essentially all subsequent compilations of active faults of Oregon. This publication provides a substantial update of known active or suspected active faults east of the Cascades. Improvements in the new map include (1) many newly recognized active faults, (2) a linked ArcInfo map and reference database, (3) more precise locations for previously recognized faults on shaded relief quadrangles...

This digital dataset, compiled from previously published andunpublished data sources, contains a personal geodatabase andraster data of features related to the repeated inundation of theWillamette Valley and Portland basin by Missoula Flood waters inLate Pleistocene time. The feature classes contained within theWill_Valley geodatabase are called 'erratics', representing thelocations of ice-rafted erratics; 'contours', representinginundation levels associated with stratigraphic evidence ofrepeated floodings; and 'geology', representing the generaldistribution of Missoula Flood deposits. A stand-alone tablewithin the geodatabase contains geologic unit descriptions forthe geology polygons contained in the 'geology'...

This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits of the Scotts Mills 7.5 minute quadrangle along the eastern margin of the Willamette Valley and adjacent lower foothills (Waldo and Silverton Hills) of the Cascade Range. The major emphasis of this investigation was to identify and map Columbia River Basalt Group (CRBG) units and to utilize this detailed CRBG stratigraphy to identify and characterize structural features. Together with the accompanying text file (geol.txt or geol.ps), it provides current information on the geologic structure and stratigraphy of the area covered. The...

This digital dataset was compiled from newly released U.S.Geological Survey 10-meter digital elevation model (DEM) data,along with stream and transportation coverages previouslypublished on the internet. This report consists of a digitalrepresentation of the physiography of the Willamette Valley.Contained in this dataset is: 1) 10-meter DEM data for the entireWillamette Valley; 2) the ARC/INFO grids used to create the colorshaded-relief and gray scale shaded-relief images; 3) thenecessary data ARC/INFO data to used to plot these data; and 4)several reports detailing the data formats (this docuement) andproducers used to create these datasets. The scale of theoriginal 10-meter DEM data should not be violated. Any...

Cell maps for each oil and gas play were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or dry. The well information was initially retrieved from the Petroleum Information (PI) Well History Control System (WHCS), which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying...
