or can anyone say if this rio source or metasource point was perhaps
specified in the mxtx1836 treaty as the summit of canby mtn
rather than the point to which the mainstream could be traced
experimentally
even above its headspring
to the crest
all as shown or implied here i hope
http://topozone.com/map.asp?z=13&n=4186424%20&e=275920&u=2&datum=nad27
such a specification would produce the mxtxus1836 position in
nlat 42deg at wlong approx 107d32m42s
for starters
but it might be possible to be more precise
if we could lay a gps on whatever the actual rio metasource point
proves to be
& then what if we actually find something on that longitude at the
mxtxus latitude
yow
a long shot
but maybe someone has done all this before
& left a marker
or better yet maybe we would have the honor of leaving a marker
what fun
anyone
