Sleeping Bear Dune
|
The tallest fresh water dunes on in the world are on our Great Lakes.
The tallest Great Lakes dunes are on Lake Michigan on the shores of the Sleeping Bear Dunes National Lakeshore. They rise over 400 feet above the lake.
 |
Perched dunes have layers of stone mixed with the sand
|
Perched dunes are steeper than dunes made of pure sand. The layers of stone stabilize these dunes.

Dunes without plants or trees growing on them are called "living dunes." These formations are still responsive to wind, waves, and gravity.
