Ohio's ghost towns are small and mostly eastern and southern. Canal towns came first: Sprucevale, on the Sandy and Beaver Canal in Columbiana County, is listed as abandoned in 1870, and remnants of the canal survive in Beaver Creek State Park. In the hills of the Hanging Rock Iron Region, 69 charcoal iron furnaces ran between 1826 and 1916, and furnaces such as Hope had company towns for their workers. Coal followed: Perry County counts about 70 coal boomtowns in the region it calls the Little Cities of Black Diamonds, and some, like San Toy, lost most of their people within a decade. Railroads made places like Moonville, a hamlet that grew along the Marietta and Cincinnati line and was abandoned by 1947.
Other towns were lost to water. Flood control reservoirs took the land of Atwood, Elk Lick and New Burlington. Utopia, on the Ohio River, began as a Fourierist community in 1844 and lost 17 people in a flood in 1847. What survives is usually a cemetery, foundations in the woods, a tunnel or a historical marker, and several of the places in our index are still small living communities. Rendville, a coal town with 28 residents in 2020, is the smallest incorporated village in Ohio.
