If you will go to the extreme close-up April 2002 "Urban Areas"
color aerial photo at
http://tinyurl.com/3kko5 , you will see the
area of the tripoint. These urban photos allow you to zoom in
several steps closer than most on the web.
You can see Virginia 123 curving across the lower left quadrant of
the photo. Note the large complex of buildings that seems to be
under construction at the bottom. It might be even commercial
rather than residential. I believe rather strongly that the
northwestern wall of this complex is up against the boundary between
Arlington and Fairfax Counties, the complex being in Arlington.
Since that boundary is the vestigial DCVA boundary, it will align
perfectly with the DCMD boundary coming from across the river.
Perhaps this will be of help in finding the precise area of the
river bank. You can click the image to zoom in one more step for
the closest view of all.
The web site at
http://www.deepwater.org/trails/#phtrail says that
there is access to the Potomac Heritage Trail at "Pimmit Run (at
Chain Bridge)" [in Arlington County], and that the "trail follows
Pimmit Run for a short distance before a low-water crossing into
Fort Marcy Park" [in Fairfax County]. Thus, the trail crosses the
county line over 300 yards away--and across a ridge--from the
tripoint on the river bank.
