One distinctive feature of Indiana’s topography is its steep dune ridges that mark shoreline features along Lake Michigan’s southeastern shoreline. The dunes are especially prominent within Indiana Dunes National Park, where they reach a height of up to 200 feet (61 meters). In addition to the dunes, other zesty features include the Hoosier National Forest, comprising more than 202,000 forested acres in 19 counties; two national rivers – White and Wabash; gorgeous river valleys; and numerous nature preserves scattered throughout the state.
