What is the authority of the GLO / General Land
Office? All the info we have seen talks about the
1909 USGS marker. Whether we can verify the center of
the 1909 disc falling on the 194-195 sightline or not,
they at least seem to have thought they placed the
marker in the right place. Then comes GLO in 1925
with this gold capped standpipe with the point
depicted. A passerby might be confused and think that
is meant to be the TP (as a latter revision?) when I
suppose they just meant it to be a witness mark for
the 1909 marker. Generally, does USGS always trump
GLO in instances where both have marked the same
tripoints? (admitedly I can't think of another
example, but perhaps another one exists.)
