The major road running Northwest to Southeast is Fairfax County Parkway (7100), intersecting 7100 is Lee Chapel Road and the minor road in the Northeast portion of the image is Yardarm Lane. The cemetery itself is in orange, and covers a decent amount of ground with four major areas of gravestones, and then in the blue marks the location of the ruins of the old Lee Chapel.
