This geodatabase, digitized from published resources, includes the position of volcanic ash-bed localities, structural data of inclined beds, orientation of geologic contacts and structural contours of specified stratigraphic horizons, and geographic extent of mapped geologic outcrops. This geologic compilation includes a geodatabase with applicable spatial feature classes accompanied by non-spatial tables with information that describes the data sources, glossary...
