How do I get to the MBMG’s ArcGIS Server?

Stop — before downloading these files please read!!!

This page provides links to the digital data zip files for the geologic maps. Each zip file will extract into a folder containing Arc/Info export files, metadata, files, and a readme file with brief unit descriptions. The export files can be imported using Arc/Info import, ArcView Import 7.1, or ArcToolbox Import to Coverage. Other utilities may be capable of importing these data sets but are not supported by the Montana Bureau of Mines & Geology. Other data formats are not available.

Digital data for USGS-produced maps are available from the USGS
