Ford County Coal Data
There has not been any mining in Ford County.
Ford County structural elevation, depth, thickness, sulfur, and chlorine maps. Scale 1:100,000. PDF files.
On demand plots available for these maps! If you are unable to make your own large size plots from these PDF's we also offer an on demand plot for individual maps from our publication and sales office—for cost of the plot and handling. Please contact the ISGS at (217) 244-2414, or email at firstname.lastname@example.org for more information on purchasing plots and other details.
Ford County Coal Logs
The PDF file contains non-confidential coal log descriptions from the Coal Section's stratigraphic database in the county listed. Coal logs are sorted by township/range and section.
You can download the raw .dbf files from which the stratigraphic database is derived (if such files are what you require; most users will only want the PDF files).
Each PDF file has a summary sheet that contains an overview of data and geology for the county. Each coal log has a "header" element that contains location information, log type, log source and other information. For each log, North American Datum 1983 (NAD83) Longitude/Latitude coordinates in decimal degrees are provided as well as a legal description which uses the Public Land Survey System (PLSS).
Beneath the header is geology information for that data point. The Coal Section stratigraphic database from which this .PDF file is derived is a multi-project database which contains drill hole and outcrop descriptions of Pennsylvanian stratigraphy in Illinois. Consequently, the level of detail and accuracy in the data and their interpretation vary (sometimes widely) with the geologist, project type, or original data source. Multiple descriptions of a particular location may be present. Note that both the coal stratigraphic database and this .PDF listing are only a subset of the total amount of data available from the ISGS Geologic Records Library archives, and reflect only coal-specific data and interpretations of past and present Coal Section geologists. They are not a comprehensive listing of all data that may be available from the ISGS.
