The National Geologic Map Database
A wealth of geologic information at your fingertips!
By David Soller, USGS Geologist
The USGS and State Geological Surveys have been making geologic maps since the 1800s - this data (and more) can be found in the National Geologic Map Database (NGMDB).
Geologic maps provide information about the earth materials beneath our homes, and are essential for energy and mineral exploration, environmental studies, hazard mitigation, and more.
Learn about the history of geologic mapping and how to access over 100,000 geologic maps and publications covering the U.S.
