The Great Lakes, and Lake Michigan specifically, are valuable in a wide range ways. In addition to the unique habitats they provide to numerous species, and the drinking water that millions of people draw from them, the Great Lakes have been valuable and vital paths for transportation and travel. A great deal of cultural and historical information and artifacts lie just beneath the surface of the Lakes, and Indiana is working to save some of that heritage.
