This prize-winning interactive map of more 1,100 sites, routes and historical Underground Railroad personages is a best-in-class tour de force of local research and application of geographic information systems. The project's lead researcher and cartographer have both won annual Free Press prizes for their work in producing this best Underground Railroad map to date.
The National Park Service's Network to Freedom program maintains an extensive listing of verified Underground Railroad safe-houses, routes and other places. Most of these listings have a Wellman Scale rating of 5—documented authenticity—which comprise about 4 percent of claimed Underground Railroad sites. To provide broader context, the listings include elements that were opposed to the Underground Railroad such as capture sites and courthouses.
This map and accompanying tour guide lay out geographically the 70+ sites and routes located in Frederick County, Maryland, and nearby that, mostly according to oral tradition, were active in the Underground Railroad.
