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.

Simplified Geologic Map of Yellowstone, modified from USGS I-711 by Marli Miller, University of Oregon. All rock material resulting from the major caldera-forming eruptions are labelled at Qt, where the dashed caldera boundary highlights the scale of these events. Older volcanic, sedimentary and metamorphic rocks are found outside of this boundary.
