1:63,360 scale, 48 x 36 inch thematic geologic map, Bear Creek Valley, Jackson County, Oregon
This map and database for Bear Creek Valley, Jackson County, Oregon, were prepared to provide a spatially accurate and detailed geologic database that compiles existing map data in a digital format consistent with the digital statewide Oregon Geologic Data Compilation database (OGDC-5). This geologic database refines our understanding of the geologic conditions that control the distribution, quantity, and quality of groundwater resources and the distribution of terrain susceptible to landslides. The database will help with assessment of regional seismic hazards and delineation of potential hydrocarbon, aggregate, and other mineral resources. The database also serves as a basis for future geologic, geohydrologic, and geohazard studies in Bear Creek Valley. The primary product of this publication is an Esri ArcGIS™ ArcMap™ 10 format geodatabase that contains detailed information on the geology of the region. The publication also includes a report describing the geology of the study area, a 1:63,360-scale thematic geologic map, and digital databases containing geochemical analyses and isotopic ages. The digital content of the publication is described in the Appendix.
The geologic map, report, and database are the product of a one-year geologic mapping program supported by the United States Geological Survey (USGS), National Cooperative Geologic Mapping Program, under assistance award number G10AC00324. Funding was also provided by the State of Oregon.
