but youve done it again maestro
for besides ruling canby summit out
you have confirmed we need to begin from the rio source
whether
the natural sawanabori headspring source
or
the meta sawanabori thalweg point on the physical crest line
somewhere still unknown above the headspring source
i am still not sure which of these 2 probabilities is correct
but i do think it is correctly either one or the other
but that is already an enormous help
& confirms my first topozone swatch was correct
for showing both the rio headspring point
at least according to this the most detailed available usgs topo
& undoubtedly also the alternative point based on it
& it also confirms texas could only lie generally northward but not
southward anywhere on the right bank
hence
the north line to the limit of mexico at nlat 42
hence the stovepipe
& its nw corner
the confirmed 1836mxtxus1845
for you have also confirmed all this was both de facto in 1836 &
projected to become de jure by both parties since 1836
& again my time is almost up
but i am deliberately going slow this time
& there is much more of interest here
so i will have to continue this in probably several more steps
so again thanx for bearing with me
