STATEMAP Products Completed

Each year the Illinois State Geological Survey (ISGS) participates in the STATEMAP component of the National Cooperative Geologic Mapping Program, which provides federal funds for detailed two-dimensional geologic mapping to state geologic surveys. The U.S. Geological Survey administers the program, and funds are distributed to state geological surveys on a competitive basis. The program also includes a federal component, FEDMAP, and an educational component, EDMAP. The ISGS encourages universities to participate in the EDMAP component and welcomes their cooperation with ongoing ISGS mapping projects.

Overall, the ISGS ranks ninth among other state surveys in federal dollars received under this program, having received more than $2.45 million for geologic mapping in the state's high-priority areas since the program's inception in 1993. The high-priority areas include the metropolitan Chicago area, where there is great demand for groundwater resources; southern Illinois, where mapping has focused on identifying economic mineral resources such as coal, high calcium carbonate, and other minerals; and the St. Louis Metropolitan East area, in order to meet the societal needs of the greater St. Louis region. Prioritization of the map areas for the STATEMAP program involves dialogue with the Illinois Geologic Mapping Advisory Committee, which includes representation from local, state, and federal government, private industry, and higher education.

The ISGS recently completed seven new geologic maps of the following 7.5-minute quadrangles at a scale of 1:24,000: Wheeling, New Athens East,New Athens West, Herod, Brussels, Winfield, and Nutwood. New geologic mapping has just begun in the following quadrangles: Zion, Aurora South, Paderborn, Redbud, Altenburg, Goram, and Shetlerville. A new proposal will be submitted in November 2008 to map in the following quadrangles: Waukegan, Highland Park, Naperville, Yorkville, Plano, Foley, Hamburg, Karbers Ridge, and Oregon. Additionally, St. Clair County will be proposed as a compilation project, based on completed detailed maps.
