A name given in the southern Atlantic States, in the region bordering on the sea and sounds, and especially in North Carolina, to a tract of land, swampy in character, often covered by a considerable thickness of half-decayed wood and saturated with water.

The Great Dismal Swamp lies on the border of North Carolina and Virginia. Much of this is a peat-bog, and a very large part is covered by a stunted growth of shrubs and dwarfed trees.
