Geologic Map of the East of Grotto Hills Quadrangle, California: A Digital Database

This digital map database represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (egh_geo.txt, egh_geo.pdf or egh_geo.ps), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller.
