Many many moons ago, the old POB magazine had a good article about restoration by area Surveyors.
It may be available through their archives but this was way before digital and internet presence.
I have visited a couple of those in Alexandria. That part of the D.C. boundary is now defunct since the portion in Northern Virginia was reconveyed back to VA in the 1840s.
I posted this website a couple of years ago, but it also has a lot of info about that boundary.

Wonder why the eastern and western corners don't appear to have been monumented?

Is that another Masonic Secret?
Thanks for posting
