by Mitchell W. Reynolds and Theodore R. Brandt, version 1.1


This geospatial database has been approved for release and publication by the 
Director of the USGS.  Although this database has been subjected to rigorous 
review and is substantially complete, the USGS reserves the right to revise the 
data pursuant to further analysis and review.  Furthermore, it is released on 
condition that neither the USGS nor the United States Government may be held 
liable for any damages resulting from its authorized or unauthorized use.

Version 1.1 is released to (a) revise on the basis of new fossil evidence the 
Cretaceous stratigraphy and nomenclature for strata the southeast part of the 
quadrangle, and (b) modify several line and polygon codes.

The database can be downloaded via the Web from 
http://pubs.usgs.gov/of/2006/1329/.  ArcInfo export files and ArcView shapefiles 
may be extracted from a gzip-compressed tar file (1329.tar.gz)or zip-compressed 
file (1329.zip).  In addition, an Adobe Portable Document Format (PDF) file 
(OFR-2006-1329_map.pdf) can be downloaded, from which paper copies may be 
printed.

The data were compiled from field mapping and published geologic map sources.  
Betty Skipp, U.S. Geological Survey, and David Fullerton, U.S. Geological 
Survey, reviewed the geologic map.  

This geospatial database consists of ArcInfo export files (.e00) and ArcView 
shapefiles contained in a gzipped tar archive or zip archive.  Both compressed 
archive files contain both types of geospatial database files.  See the list 
below.  Please refer to the file 1329.met for detailed metadata documentation 
for this geospatial database.
