Arlington survey maps 1943 - Photo #3 - Hall's Hill above Lee Highway

Plat Book Plate 11; click the Enlarge button to see details. This shows the part of Hall's Hill north of Lee Highway between George Mason Drive and N.Columbus Street, labeled as Garden City Section, extending north to somewhere between 24th and 26th Street. There seems to be a thicker black line where the Wall would be: parallel to N.Columbus, then across 25th to George Mason, then down George Mason to Lee Highway. Also note the little black lines where 25th Street, 25th Road, and 25th Place meet George Mason. I wonder what the big blue area is at the lower right along Dinwiddie Street.
