The Quaternary Geologic Map of the Chicago 4 Degree x 6 Degree Quadrangle, United States, I-1420 (NK-16) was compiled by Jerry A. Lineback, Illinois State Geological Survey, Ned K. Bleuer, Indiana Geological Survey, David M. Mickelson, Department of Geology and Geophysics, University of Wisconsin, William R. Farrand, Department of Geological Sciences, University of Michigan, and Richard P. Goldthwait, Department of Geology and Mineralogy, Ohio State University. The state compilations were edited and integrated by Gerald M. Richmond and David S. Fullerton, U.S. Geological Survey. The compilations of geology and glacial features were converted to digital form by Techni Graphic Systems, Inc., of Fort Collins, CO, under contract with the U.S. Geological Survey and modified by Charles A. Bush. The hydrography layer was prepared by Sharon Smith, U.S. Geological Survey. Illustrations, wordprocessor files, the topographic layer, and DLG coverages were prepared by Bush.

In recent years, surficial deposits and materials have become the focus of much interest by scientists, environmentalists, governmental agencies, and the general public. They are the foundations of ecosystems, the materials that support plant growth and animal habitat, and the materials through which travels much of the water required for our agriculture, our industry, and our general well being. They also are materials that easily can become contaminated by pesticides, fertilizers, and toxic wastes. In this context, the value of the surficial geologic map is evident

Goldthwait (comp.), 1983, Quaternary Geologic Map of the Chicago 4° x 6° Quadrangle, United States: Miscellaneous Investigations Series I-1420 (NK-16), U.S. Geological Survey, Reston, Virginia.

Compilation of geologic data:
The accuracy of the map data is dependent on (1) the accuracy of the
original source data, (2) the accuracy of transfer of that data to
larger scale bases by the compilers, (3) the procedures by which the
compilers and the editor/integrator simplified or generalized the data,
and (4) the procedures used by, and the objectivity exercised by, the
editor/integrator in integration of adjacent parts of the map that were
prepared by different compilers. Consequently, aspects of accuracy for
the data set cannot be quantified.
Digitization and attributing of compilation:
Digitizing contractor scanned source stable-base material, vectorized
scan, attributed files, and produced check plots and coverages.
C.A. Bush proofread check plots and reviewed digital files; made final
corrections as needed; produced graphical files and imported them into
graphics program to prepare plot file; proofread cartographic
product; prepared illustrations and word processing files of
descriptions of map units and sources of information. The original
paper map was scanned and recreated as PDF files. (The original map was
thoroughly reviewed for conformity with U.S. Geological Survey
editorial standards and stratigraphic nomenclature.)
The accuracy of location of polygons, lines, and points is consistent
with the map scale of 1:1,000,000.
These coverages contain polygons for all the map units, lines for all the contacts and glacial features, and points for all the locations of localities and drumlins. All geologic data from the original map are expressed on this map. Any differences between elements on the original map and attributed polygons, arcs, and points in this database are inadvertent and should not be construed as deliberate alterations of the data.
Polygon and chain-node topology are present. The ARC/INFO commands BUILD
and CLEAN were run to ensure the topological consistency of the data set.
All polygons are labeled and were tested by using the ARC/INFO command
LABELERRORS. All polygons were checked for closure and intersections.
Are there legal restrictions on access or use of the data?

- Acknowledgment of the Quaternary Geologic Atlas of the United States of America and (or) the U.S. Geological Survey in products derived from these data will be appreciated.
