On Lake Michigan

Lake Michigan is one of the Great Lakes and the only one that lies entirely within the United States. Wisconsin, Illinois, Indiana and Michigan share its shoreline. It is a glacial lake about 307 miles long and 118 miles wide, with a surface area of about 22,300 square miles. About 13,237 square miles of that area lies in Michigan. The lake averages 279 feet deep and reaches about 923 to 925 feet at its deepest point. Including islands, it has more than 1,600 miles of shoreline. The wide Straits of Mackinac connect it to Lake Huron, and the two share the same surface elevation, so hydrologically they form a single lake. Rivers flowing in include the Fox, Grand, Menominee, Muskegon, Kalamazoo and St. Joseph. Long bays line its northern end: Green Bay in the northwest and Grand Traverse and Little Traverse bays in the northeast. More about Lake Michigan.
