Answer:
The Western Great lakes Subregion
Explanation:
The Easter United States is divided into 4 Subregions:
Southern: Florida, Mississippi, Alabama, Georgia, South Carolina.
Central: Kentucky, Tennessee, North Carolina, Virginia, West Virginia.
Northeastern: Pennsylvania, New York, New Jersey, Connecticut, Rhode Island, Massachusetts, New Hampshire, Vermont, Maine.
Western Great Lakes: Ohio, Indiana, Illinois, Wisconsin, Michigan.
The Atlantic Ocean borders the eastern United States in 3 Subregions; Southern (Florida, Georgia, South Carolina), Central (North Carolina and Virginia), and Mostly northeastern region from Maryland coast to Maine.
The Western great lakes do not border the ocean, but they border great lakes like Lake Michigan instead.
