Reminds me of another unknown “border dispute” I read about, where a Canadian psychologist was permanently barred from the US, because he wrote about taking LSD in the 1960s: https://www.wired.com/2007/04/canadian-psycho/
Maybe the authors of the article didn't include the northwest passage dispute?
Looking at the map, it's amazing how far down Alaska goes...halfway to meeting US, mainland border.
