Glenwood Shoreline

From Wikipedia, the free encyclopedia

The Glenwood Shoreline is an ancient shoreline of Lake Michigan. It is named after the town of Glenwood, Illinois. The shoreline was formed when Lake Michigan was higher during the Ice Age when ice blocked the Straits of Mackinac and after the straits were freed the lake receded and left behind a sand ridge where the shore was. This ridge can be seen clearly in Glenwood, Illinois, Dyer, Indiana, and Schererville, Indiana, all south of Chicago.
