Around the year 400 AD, the area experienced an environmental transformation. The sand dune of Roanoke became disconnected from the mainland by water, and inlets in the Outer Banks turned freshwater sounds (lagoons) into brackish ecosystems. The land termed Roanoke Ridge became Roanoke Island. From approximately 460 AD to 800 AD, the Mount Pleasant Culture had a village on the Tillett Site in southern Roanoke Island, within the modern-day Wanchese township. After the year 800 AD, the village was occupied by the Colington Culture, a predecessor to the historic Roanoke tribe, who were encountered by the 1584 English Expedition.
