of course grant
nice going
& sock it to us
about bwnazmzw
i have also been thinking that the existence of the kasane kazungula
ferry so called across the zambezi per se suggests a bwnazm plus
bwzmzw pairing rather than the other way round
even regardless of the icj decision that fixed the bwna line into the
left channel of the chobe & thus very probably also fixed the thalweg
junction at a higher point on the zambezi than the bwzw line or than
these ferry termini in botswana & zambia respectively
tho my conclusion upon these icj data is still conjectural
for only text & no map was published by the court
& about frgbnlus
i am pretty sure st martin has only the single grandiose monument at
the main road crossing
& i do recall a lot of actual confusion on this island that prides
itself in being a single community & practically ignoring the
boundary except to monumentalize that singularity
so unless there is some crystal clear documentation somewhere
which i doubt
i think it should be an ongoing madcap scenario as to which coast the
frnl line actually emerges at
about cocrnipa
san andres etc on the ground is clearly colombian
with regular air service etc
if that helps
finally arent there also 2 tridominial territorial quadripoints in
the gulf of fonseca
