Welcome Eric!
And...
The US-Canadian border is where it is. In reality, it is not very accurate. There is a graph of the deviations along the 49th out there somewhere. But at the end of the day, the Americans and Canadians agree that the border lies where it was marked. If the border slides north of the 49th (west of Lake of the Woods), then there is no change in the actual frontier legally.
They Boundary Commission does use a series of Geodetic points for boundary marking... though these would move in your scenario as well.
As for your final question: Uh, I dunno!
Barely North of the 49th,
Doug

Since the continents are adrift on the sea of magma and the Prime Meridian goes through Greenwich, the longitude of a place changes as time goes by. Also, the plates can also move north and south, and so latitude is also variable. Yeah, it's slow enough that we probably won't notice, but if the Americo-Canadian border is actually the 49th parallel, then if North America is moving generally north, is the US "conquering" Canadian territory even as I type this? (I don't actually know which direction North America is moving. Can anyone help?) If we wait long enough, will Cheyenne leave the state that it is the capital of?<image.tiff>
Or, is the actual border a line on the continent connecting a bunch of key points that were determined by what their latitudes and longitudes were when a border dispute was settled?
This is my first post as I'm new to the group. I have a question about the shorthand used to indentify boundary corners. Is it the two letter codes used for web addresses in English alphabetical order? And on another note, if Croatia's abbriviation HR is derived from its name in Croatian, why then is Hungary's HU not derived from Magyarorsz·g?
