The mapped units include glacial till that is interpreted to have been deposited during the Wisconsin Glaciation. The last major expansion of the North American Laurentide Ice Sheet occured in the Wisconsin glacial episode. Derived by extracting and interpreting elements of a preexisting published digital data source: Quaternary geologic map of Indiana, Indiana Geological Survey Miscellaneous Map 49.
