About this map

The Great Dismal Swamp dominates this landscape, showing the complex network of historic waterways that define this protected wilderness. In the late 1970s, the Great Dismal Swamp National Wildlife Refuge was managed through a system of geometric canals and drainage paths, many bearing the names of early land ventures and industrial efforts. Long, straight channels like Washington Ditch, Portsmouth Ditch, and Jericho Ditch cut through the dense vegetation, illustrating the massive hydrological engineering required to navigate and drain the wetlands.
