Are there geologic maps or publications for where I live?
Detailed geologic mapping has not been completed for the entire United States, but maps are available for most locations.
- Geologic maps at many scales and from many sources are listed in the National Geologic Map Database.
- Some geologic maps can be purchased in hard copy through the USGS Store.
- Download digital geologic maps for entire states from the USGS Mineral Resources Online Geospatial Data (MRDATA) website. Scroll down to the "Geologic Data" section.
- Contact your state geological survey. Many state geological surveys have detailed maps that can be downloaded or purchased.
- The USGS Publications Warehouse lists all published USGS geologic maps (which are also on the National Geologic Map Database). Geologic maps and publications are often referenced to county names and/or topographic quadrangle names, so try searching on those keywords along with other locality keywords.
- Your public library might also have good resources.

Alaska geology revealed
This map shows the generalized geology of Alaska, which helps us to understand where potential mineral deposits and energy resources might be found, define ecosystems, and ultimately, teach us about the earth history of the State. Rock units are grouped in very broad categories on the basis of age and general rock type. A much more detailed and...
