Bedrock and Quaternary Geology and Hydrogeology
Minnesota Geological Survey
State Map Series: These maps are part of the MGS "State Map Series". Scales are 1:500,000 to 1:1 million.
- Bedrock Geology - Map S-21
- Bedrock Hydrogeology - Map S-2
- Depth to Bedrock - Map S-14
- Quaternary Geology
- Map S-23 (newer): The GIS data is more detailed than the map and will be updated as new mapping is completed

- Map S-1 (original): Link to PDF map, GIS data, and metadata
- Quaternary Hydrogeology - Map S-3
Online Map Services: MGS is in the process of migrating maps and digital information to online versions in an effort to increase accessibility and provide for more general use. They are doing this through web-enabled map services. Services offer access to some State Map Series maps and mosaics of more recent, high-resolution data sets.
