This 1956 
              Fairfax County Property/Zoning map clearly shows not only the main 
              channel of the western fork of Burke's Spring Branch, but also the 
              side channel leading from Burke's Spring 
              into the branch. Oddly, the only part of the eastern fork shown 
              is the underground culvert (indicated with dotted lines) carrying 
              it under lot 9 of Kirby Ct.
