Locate Ancient Beaches After the retreat of the glacier, the lakes were formed, hut the present boundaries were covered then. The ancient beaches and shore lines formed by the retreat of Lake Michig-an to its present boundaries are found in Heverly Hills, Evanston, Mount For. est. Riverside, Stony Island and Worth. The whole Calumet district was once covered bv the waters of "Lake Chicago," as Lake Michigan was formerly kno\\·n, and Palos Park and Hinsdale were nearly on the shore, the map shows. Des Plaines, once situated on an arm of the old lake, is the location of 'l flood plain that tells its own history. This region is also one of glacial moraines. Lemont, the museum map shows, is the only d.istrict in the vicinity in which are found fossils, direct e\·idence of the types of earlier animal life. Proofs of Glaciation In the region of Barrington are found some of the best proofs of glaciation.

Young valleys that wind and water erosion may in time enlarge to greater proportions can be studied along the north shore from Glenc e to Waukegan. The 'vhole beach from Evanston to Waukegan tells the stories of new beach formation, lakP deposits, ancient beaches, shore cliff building and wave cutting. Dunes Rich for Research Another region rich in material is that along the southern shore, from the THE LINEN STORE Inc. Calumet district along the Indiana shore-the dune country. The ma'p University Club Bldg. 36 So. Michigan Blvd. shows this area to give opportunity for CHICAGO study of unique dune and beach formations, such as beach formations, lagoons and sand dunes, im:lpding the peculiar barean, or crescent-shaped dune that "The ma.!.~ serves to bring to the attention of the city dweJicr th'e attractions of the region aDout him," Mr. Bailey :~aid.
