Great Lakes Dunes

It's in the mail: Great Lakes dunes featured on U.S. postage stamps

The Great Lakes sand dunes, one of the largest freshwater dune systems on the planet, are featured on postage stamps issued by the U.S. Postal Service last October. The 10-stamp sheet, which portrays 27 images of the flora and fauna of the dunes (and even Petoskey stones), was released at a ceremony at the Sleeping Bear Dunes National Lakeshore in Empire, Mich.
