Recognition:
Size: 1200 acres
Location: In Berrien County, approximately 6 miles southwest of St. Joseph
Management: Warren Dunes State Park
Activities: Hiking, hunting, fishing, outdoor education, birding, cross-country
Importance: The magnificent high-relief dunes in Grand Mere were formed approximately 10,000 years ago during the recession of glacial lakes. They are a natural phenomenon not found anywhere else in the world. Located between Lake Michigan and several inland lakes and unique wetlands, the dunes afford an excellent perspective of the surrounding region. The lakes and wetlands provide a unique ecological area that encompasses the full range of open water aquatic to closed forest terrestrial communities. The wetlands and lakes are significant waterfowl and songbirds migrating areas.
