NC Geologic Maps

The NC Geologic Survey (NCGS) has scanned it's holdings of hundreds of geologic maps covering North Carolina. The originating sources for these maps are the USGS, NCGS, and theses and dissertations. The map images were georeferenced by NCSU Libraries and compressed into MrSID format as part of the NC Geospatial Data Archiving Project.
