yes
the tripoint marker did very effectively announce itself as the
mdpa3frfrwa tripoint
by naming both maryland counties in full on their respective sides of
its nicely rounded ridge top
& adding a p for pennsylvania on the flat north face
clearly it was an authoritative maryland rock
the point indicated on the topo as the tripoint was occupied by a
standard ubiquitous pennsylvania roadstone
but i am no longer even surprised to find the usgs wrong on essential
data
