welcome walt

bp discussions on these topics began around message 222
which will give you at least some of your answers

in all i believe at least 6 such american tongues have been
identified so far
namely
point roberts
nw angle
elm point also in lake of woods but pointing south across 49th p
smaller unnamed tongue just west of elm point
the greater alburg vermont area
& a smaller vermont tongue called province point i believe

& there is a unique canadian counterpart
at st regis quebec
near hogansburg ny

all 7 of these can be found pretty easily on topozone as i recall


about the history of the nw angle
it became american territory by the treaties of 1783 & 1818

the inclusion of the area in the usa resulted from the use of
inaccurate maps by the treaty makers

a 1917 caus boundary commission described it as a
politico geographical curiosity
that a glance at the map will show no one could have foreseen
& that would be inexplicable without some knowledge of the
steps in the process by which it was brought about

the 1818 treaty stated
it is agreed that a line drawn from the most northwestern point of
the lake of the woods along the 49th parallel of north latitude
or if the said point shall not be in the 49th parallel of latitude
then that a line drawn from the said point due north or south
as the case may be
until the said line shall intersect the said parallel of n lat
& from the point of such intersection due west
along & with the said parallel
shall be the line of demarcation between the usa & gb etc etc

it wasnt until 1824 that a physical survey established the facts
& resulted in the present configuration of the boundary

taken from boundaries of the united states & the several states

which btw also says michigan got the np in several stages
the eastern part in 1805
the middle in 1809
& the west in 1818
but with the western boundary not completed til 1836
