County Maps

Map of Illinois showing counties that have been mapped.

County mapping is carried out at the ISGS under a variety of programs. The programs exist for different purposes and require different levels of scientific review. Maps are published in specific Series based on the program under which they were created and the corresponding level of review. The links on this page access all downloadable county-scale maps except Coal, Oil, and Gas, which are maintained separately. Please use the Coal Maps and Oil and Gas Maps links to access those maps.

The ISGS Library page provides links to catalogs of ISGS maps and publications.
