The marker reads:
"Abandoned Shoreline of Lake Michigan
This ridge is an ancient beach or sand bar of Lake Michigan whose waters reached this point 8,000 years ago when the lake level was 20 feet higher than now. Clark Street runs north atop this ridge. The park ponds lie between such old beaches, abandoned by the shrinking lake. The outer boundary of Diversey Harbor and the boat slip running south of it to North Avenue are man-made land. The Chicago Park District"
