it is almost undoubtedly parallel to arfa but most probably at a
short remove from it rather than directly up against it
since constructing anything directly up against a property line is
usually forbidden by suburban building codes
my guess is the offset here should be at least 3 feet
but we might do equally well using the pavement change &
welcome signs on route 123
& then following the blue ribboned survey stakes from there
if indeed they are still in place along the combined property &
county line
all the way to the top of the cliff where they end
& then eyeballing back up toward them from the base of the cliff
in order to continue the alignment to waters edge
or at least that was my technique back then
but it must be said
that try was only approximate because i could only see the last
blue ribbon position from the river bank
whereas at least 2 ribbons in view at once would of course be
needed for anything resembling a true alignment
& i never found the wm1 marker on that alignment
indeed i never recovered it at all
of course my try was correctly focused on the low water line
so no wonder i missed or overlooked it at the high water line
but a more careful reading of the topo & bus&ss would have told
me even back then that i wasnt ultimately looking for dcva wm1
anyway & not at any water line
since it is not the dcmdvan marker
but only the next best thing to dcmdvan
still
the retry obviously needs to focus first on recovering this marker
precisely because it will suggest or actually indicate the best
available alignment of dcmd
& from a distance of only 1 tripointing stitch away from dcmdvan
rather than from all the way over the horizon

the boundary will but as noted probably not the building

good finding
so thats a dead end
but fortunately your new improved aerial view does give us a
great peek & some hope at least of walking up the right bank of
the potomac from the mouth of pimmit run anyway
just as mike & i imagined the trail might do for us
except on our own
for even if this route is too hairy for a regular hiking trail to follow
it might still be a tad less hairy than trespassing down the cliff
