Sleeping Bear Dunes National Lakeshore was authorized by congress on October 21, 1970.  It encompasses a 35 mile stretch of Lake Michigan's eastern shoreline and North and South Manitou Islands.  The Park was established to preserve the "outstanding natural features, including forests, beaches, dune formations, and ancient glacial phenomena...for the benefit, inspiration, education, recreation, and enjoyment of the public."  The Lakeshore also contains many cultural features including an 1871 lighthouse, three former U.S. Life-Saving Service or Coast Guard Stations and an extensive rural historic farm district - Port Oneida.
