Preliminary Digital Geologic Map of the Santa Ana 30' x 60' Quadrangle, Southern California

Compiled by: D.M. Morton

Digital preparation by: Rachel M. Hauser and Kelly R. Ruppert



Open-File Report 99-172 is a digital geologic data set that maps and describes the geology of the Santa Ana 30' x 60' quadrangle, southern California. The Santa Ana quadrangle database is one of several 30' x 60' quadrangle databases that are being produced by the Southern California Areal Mapping Project (SCAMP). These maps and databases are, in turn, part of the nation-wide digital geologic map coverage being developed by the National Cooperative Geologic Map Program of the U.S. Geological Survey (USGS)

The two plotfiles are formatted to plot on 30 by 60 inch or larger sheets, so a large-format color plotter is required to produce a paper map. The best plotting results will probably be obtained when using the PostScript files.
