+ About this map
Lake Michigan is the only Great Lake that lies entirely within the United States, a 307-mile-long basin gouged out by lobes of the last ice sheet. Chicago and Milwaukee face each other across its southern end, dunes line the Michigan shore, and the Door Peninsula walls off Green Bay in the northwest. It is an inland sea in every practical sense, with weather and horizons to match.
The depth contours reveal a lake built in two parts. The southern basin is a broad, gentle bowl, its lines widely spaced, while north of the mid-lake rise the floor drops into the deep northern basin, bottoming out at 886 feet. The map shows Green Bay and Grand Traverse Bay as shallow side chambers, the long even shelf along the eastern shore, and the tight gradient where the deep water presses toward the Straits of Mackinac.
