The thriving metropolitan area extending inland along 70 miles of Lake Michigan shoreline—known as Chicagoland—was made possible by glacial and coastal processes. This map poster provides a visual perspective of the area not available from the ground. The accompanying text explains how geologic processes laid the foundation for the development and continued prosperity of the state's largest city. Today evidence of these processes is revealed by four distinct landscapes: (1) the rolling hills and ridges of Wheaton Morainal Country; (2) the Y-shaped Chicago Outlet Valley that made possible the historic Illinois and Michigan Canal, the Chicago Sanitary and Ship Canal, and the Calumet-Sag Channel; (3) the Chicago Lake Plain, a low-sloped expanse of land that holds most of the City of Chicago; and (4) the Zion Beach-Ridge Plain, a migratory coastal sand plain.
