You can now geographically search thousands of Geology Maps & Reports with a single click at Land Matters.

The National Geologic Map Database (NGMDB) is a project of the USGS and the best source available for locating geologic maps. You can now search the NGMDB catalog of geologic maps directly from all Land Matters Geology Maps.

This targeted search is a quick way to get the Geologic information you need for your research.


Take me to the Geology Maps
Choose a Geology Map from the right side menus, ZOOM IN and use the Identify Tool to query the map. In the results window use the Click for Map List link to access the available maps.

A new tab will open in your browser that shows a list of geologic maps in your area of interest. To keep the list manageable, we have limited the search criteria to bedrock and surficial geologic maps with a scale between 1:1 and 1:500k that are within the 24k quadrangle that you selected. This will provide the most detailed maps available.
