So, I just ran down this little rabbit hole for a few minutes ... really crazy ...

Congress' original intent might be as much as 2.5 miles off the current boundary between Utah/Colorado and AZ/NM ... current technology might say off by 1800 feet the other direction ... legal law say we don't care about the math we care about the marker so it's not off at all, by definition.

AND check out GoogleMaps which shows the Utah / Colorado state line with a nice little jog just a bit north of the monument to try to line up the monument while not messing up the other hundreds of miles of border that are well established ...

Question ... do other state borders move around a bit? For example, some borders are based on the river paths.... but rivers CAN move? If the river coarse defines the state boundaries, and the river course moves, does the state boundary move too? I would guess NO, at least not any more ... but that probably means somewhere there are probably some funny state boundaries that follow the river for a while, then jump out of the river for a while (and follow the FORMER river course) and then jump back onto the river course again....

just a crazy thought to start a tuesday morning!!!
