Do they have sand dunes in Michigan?

Yes, Michigan has sand dunes. The state is home to some of the largest freshwater sand dunes in the world, located along the eastern shore of Lake Michigan. The Sleeping Bear Dunes National Lakeshore is a popular destination for visitors looking to hike, swim, and enjoy the natural beauty of the area. The dunes here were formed by the glaciers that receded from the area about 11,000 years ago. The wind has since shaped the dunes into the beautiful formations that are seen today.
