There are only two sand dunes in Michigan. The two sand dunes are Sleeping Bear Dunes and Sliver lake sand dunes.
Sand hills form in areas where wind can easily transport and deposit sand, such as deserts, beaches, and coastal regions. They can also form in places where sand dunes have been stabilized by vegetation.
Scientificly, sand dunes were formed by chemical weathering.
