Indiana Dunes State Park is an Indiana State Park located east of Chicago, Illinois, United States. The park is bounded by Lake Michigan to the northwest, and is surrounded in the east, south and west by the Indiana Dunes National Lakeshore, a unit of the National Park Service. The Dunes Nature Preserve makes up the bulk of eastern part of the park, and includes most of the park’s hiking trails and dune landscape. This was one of the first places Richard Lieber considered when establishing the Indiana State Park system. Like all Indiana state parks, there is a fee for entrance. It was designated a National Natural Landmark in 1974.〔(National Park Service: National Natural Landmark Program (Indiana) ) Retrieved 4 December 2014〕 Preserving the Indiana Dunes has resulted from the efforts of many citizens and politicians.〔Smith, S. & Mark, S.

As the lake level of Lake Michigan dropped at the end of the Ice Age, the shoreline receded, and new dunes were formed along the lakeshore. Vegetation took over the previous dunes, and eventually forests grew on top of them. There are "blowouts" along the dunes, where dead stumps were revealed after the wind blew away the sand from on top of them; the most notable such blowout is Big Blowout.
