Statewide Coal Maps

Coal resource maps on this page include structural elevation, depth, thickness, sulfur, and chlorine of major, potentially minable coal seams in Illinois. These include the Colchester, Danville, Davis, Dekoven, Herrin, Jamestown, Seelyville, and Springfield Coals. The maps presented here are page-sized (8.5 × 11 inches) maps available as PDF files. Herrin Coal structural elevation maps at a scale of 1:500,000 also available.

Note: These maps are made available at this time in draft form only. They have not yet been reviewed to the normal standards of the Illinois State Geological Survey (ISGS) review process. They are made available in this manner as an "open file" in order to deliver products to our customers as fast as possible and to meet particular needs that we have encountered in public requests for this information.

These maps are found as .PDF files, requiring Adobe Acrobat™ for viewing. (Download Acrobat).
