crab apple trees. Picnic grounds and camping places could be set aside 

 here and there along the valley with connecting driveways and con- 

 venient foot and bridle trails. The DesPlaines woods are especially 

 rich in spring flora and the flood plains are a notable sight when the 

 smaller flowering trees are in full bloom. The forests are of the typical 

 oak, hickory, elm and maple type, with linden, ash, hackberry, walnut, 

 and various other trees well-represented. A rich undergrowth of 

 witch-hazel, gray dogwood, viburnums, bladdernut, osier dogwood, 

 hazelnut, and other interesting shrubs contribute greatly to the charm 

 of the woodland. 



The area lying between the DesPlaines River and Lake Michigan 

 is traversed throughout much of its extent by morainic ridges parallel 

 with the river and Lake Michigan. These belong to what is known 

 geologically as the latter Wisconsin morainic system and they mark 

 the last successive stages of the retreat of the ice mantle which finally 

 withdrew into the basin now occupied by Lake Michigan. The last 

 of these morainic ridges formed in the way mentioned fronts the shore 

 line of Lake Michigan and has located upon it such cities as Highland 

 Park, Lake Forest, Lake Bluff, North Chicago and Waukegan. 

 Between this ridge and the parallel ridge immediately to the west is a 



shallow valley known as the 

 Skokie. This is drained by 

 the Skokie stream which can 

 be traced southward from 

 near the latitude of Wauke- 

 gan to a point within Cook 

 County, seventeen miles 

 away, where it discharges 

 into the north branch of the 

 Chicago River. During the 

 last five or six miles of
