Geologic Map of the Canyon Ferry Dam 30' x 60' Quadrangle, West- Central Montana By Mitchell W. Reynolds and Theodore R. Brandt 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. The database can be downloaded via the Web from http://pubs.usgs.gov/sim/2005/2860/. ArcInfo export files and ArcView shapefiles may be extracted from a gzip-compressed tar file (2860.tar.gz) or zip-compressed file (2860.zip). In addition, Adobe Portable Document Format (PDF) files can be downloaded for each map sheet and the pamphlet, from which paper copies may be printed. The database contact is: Mitchell W. Reynolds 303-236-8007 mwreynol@usgs.gov U.S. Geological Survey Box 25046, Mail Stop 980 Denver, CO 80225 The data were compiled from field mapping and published geologic map sources. Karl Kellogg, U.S. Geological Survey, and Catherine McDonald, Montana Bureau of Mines and Geology, 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 2860.met for detailed metadata documentation for this geospatial database.
