Description:The most important factor influencing shoreline behavior in the Great Lakes is fluctuation in lake-level. Previous studies in the Lake Michigan basin suggest that large-magnitude variations in lake-level occurred in the past and that the short historical record for Lake Michigan does not contain such large variations. The purpose of this report is to describe the history of lake-level fluctuation in the southern part of the Lake Michigan basin based on an examination of northwestern Indiana beach ridges. The pattern of lake-level behavior over the past 4,000 years in two parts of Indiana's shoreline is examined; during that time, the lake level reached altitudes above those observed in the historical record for Lake Michigan.
