The Fifty-Fourth Parallel North is a circle of latitude that is 54 degrees north of the Earth's equatorial plane. It runs through several countries, including parts of Canada, Russia, and Norway. This parallel is significant in geography and climate, as it marks a region that experiences cold winters and mild summers. In North America, the Fifty-Fourth Parallel North is notable for its proximity to the Alaska border and the Canadian Rockies. It is also historically important, as it was once a point of contention in the Oregon boundary dispute between the United States and Great Britain in the 19th century.
