Were the Sleeping Bear Dunes formed from/by faulting, folding, or neither?

Answer 1

Experience The Beauty Of The Sleeping Bear Dunes. The hills, dunes, valleys, shoreline, small lakes, and streams which you'll see throughout the area were formed by the powerful earth-moving forces of ice, wind, and water over time. During the Ice Age, continental glaciers spread southward from Canada repeatedly burying the area under ice.
