1: NY city on the East coast of N. America lies further west than Santiago the capital of Chile on the West coast of S. America
2: The Atlantic opening of the Panama canal lies further west than the Pacific opening.
It is predominantly French speaking, is 1° further north than Dunkirk, is incorporated as Ville de Fermont, has a population of about 2400.
It also has a Wikipedia page that claims "Fermont is arguably the world's northernmost Francophone settlement of any considerable size": https://en.wikipedia.org/wiki/Fermont.
The reason is most of the population is in Ontario and Quebec, and the majority of that population is south of the 49th. The southernmost part of Canada at Niagara falls is actually at the same latitude as northern California. Which is why it is a big wine growing region.
And I was the nerd in high school pointing out Rome is north of NYC.
The ocean changes temperature very slowly. In summer it's colder than land, and in winter it's warmer. This acts to keep land temperature semi stable over the seasons.
Inland there are no such dampeners. Summers get real hot and winters are very cold.
Which is why Edmonton probably (I haven't checked) has much colder winters than northern Norway.
I haven't done the deep research to confirm that, so just take this a me spreading a rumor.
* The US state closest to Africa is Maine.
* New York City is south of Rome.
* Los Angeles, California is east of Reno, Nevada.
Another one (somewhat more obvious) is that the southernmost point in the USA is on the Big Island of Hawaii.
