yes
thanx
& there are of course many slight divagations of the various state &
county boundaries from the true blue ridge
not only here around frfrwa
the apparent starting place
but all down the line
& the 1824 survey separating these 2 maryland counties must have
been just as much of a rationalization of the actual ridge line as
the 1997 vawv survey is at & below mdvawv
but funny that the usgs still hasnt gotten wind of this
