Back in the early 19th century, when Ohio is getting admitted as a state, their northern border was defined as being a straight line that would stretch from the bottom of Lake Michigan over the lake, eerie like with all of these other situations, though, the geographic knowledge of the area at the time was very poor, and it ended up being discovered later that Lake Michigan stretch further south than what was previously believed.
早在19世紀初,當俄亥俄州要被接納為一個州的時候,他們的北部邊界被定義為一條直線,會從密歇根湖的底部延伸到湖面上,詭異的就像其他這些情況一樣,不過,當時該地區的地理知識非常貧乏,結果後來發現密歇根湖比之前認為的還要往南延伸。
