The United States Postal Service is rolling out a collection of Forever Stamps featuring 12 waterfalls and Grotto Falls in the Great Smoky Mountains National Park is among them. WVLT reports Grotto Falls is the only waterfall in the Smokies that takes hikers behind the falling water. The photo for the stamp was taken by Joe Miller. Upper Falls along the Blue Ridge Parkway in North Carolina also made the cut Tim Fitzharris took the Upper Falls photo.
