The Great Dismal Swamp is a marshy area in the Coastal Plain Region of southeastern Virginia and northeastern North Carolina. It is a southern swamp and one of the last large, wild areas left in the Eastern United States. North Carolina has a large refuge, as well as preserved, and protected areas. The swamp was a refuge for runaway slaves in the 1800's. Lake Drummond sits in the center of the swamp and is a remarkably circular natural lake.
