Geologic Map of the Devore 7.5' Quadrangle, San Bernardino County, California

By D.M. Morton and J.C. Matti

Digital preparation by G. Morton, C. Koukladas, and P.M. Cossette

Thumbnail of and link to map PDF (3 MB)Summary

This Open-File Report contains a digital geologic map database of the Devore 7.5' quadrangle, San Bernardino County, California, that includes:

1. ARC/INFO (Environmental Systems Research Institute) version 7.2.1 coverages of the various components of the geologic map

2. A PostScript (.ps) file to plot the geologic map on a topographic base, containing a Correlation of Map Units diagram, a Description of Map Units, an index map, and a regional structure map

3. Portable Document Format (.pdf) files of:

a. This Readme; includes an Appendix, containing metadata details found in devre_met.txt

b. The same graphic as plotted in 2 above. (Test plots from this .pdf do not produce 1:24,000-scale maps. Adobe Acrobat page-size settings control map scale.)

The Correlation of Map Units and Description of Map Units are in the editorial format of USGS Miscellaneous Investigations Series maps (I-maps) but have not been edited to comply with I-map standards. Within the geologic-map data package, map units are identified by such standard geologic-map criteria as formation name, age, and lithology. Even though this is an author-prepared report, every attempt has been made to closely adhere to the stratigraphic nomenclature of the U.S. Geological Survey. Descriptions of units can be obtained by viewing or plotting the .pdf file (3b above) or plotting the postscript file (2 above). If roads in some areas, especially forest roads that parallel topographic contours, do not show well on plots of the geologic map, we recommend use of the USGS Devore 7.5’ topographic quadrangle in conjunction with the geologic map.
