Indiana Dunes National Lakeshore
stretches along 15 miles of the southern shore of Lake Michigan in northwest Indiana
The uniqueness of this national park
is the result of natural processes that are not duplicated on this scale anywhere else in the world. Here, along the 300-mile long lake, glacial sands were deposited from the east and west sides to form 250 foot high dunes under the power of strong north winds and high waves rivaling the ocean. The resulting environment is a unique series of long dunes separated by marshes.
