The West Branch Delaware River and East Branch Delaware River dominate this 1920s topography, winding through the narrow valleys of Delaware County. The New York Ontario and Western RR tracks follow the river's path, serving as the industrial backbone for riverside settlements like Walton, Beerston, and Rock Rift. This era reveals a dense network of local education, with dozens of rural schoolhouses such as the Knickerbocker School, Finch Hollow School, and Spooner Brook School tucked into the hollows.
