Nearly 300 barrier islands encircle the eastern United States, running along the eastern seaboard from Maine to Florida and across the American Gulf Coast. The Outer Banks archipelago stretches from the southeast corner of Virginia, down much of the of North Carolina coast. The Outer Banks separate Albemarle Sound, Currituck Sound and Pamlico Sound from the Atlantic Ocean. - AsNotedIn

The Atlantic and Gulf Coastal Plains are relatively flat and slope gently seaward to a generally wide submarine Continental Shelf. The shore zone, or interface between the land and sea portions of the coastal plain, consists of a series of barrier islands 2 to 20 miles offshore. Most are low islands 1 to 3 miles wide and 10 to 20 miles long. The highest topographic features are sand dunes usually 10 to 20 feet above sea level. In a few areas, such as Jockey Ridge near Nags Head, North Carolina, unvegetated dunes reach a maximum height of 120 feet. - USGS
