There's an entertaining CGP Grey video about other oddities in the US-Canada border. ▶ this video Considering how inconvenient it is in some geographies and how small the patches of land are, I'm always surprised the State Department doesn't negotiate a land exchange treaty with Canada to fix what are essentially cartography bugs.
