I am not any kind of a history student but did you know that once upon a time there was a state named Franklin? https://www.atlasobscura.com/articles/americas-lost-state-franklin
Franklin is one of my favorite geographic anomalies. The other is that in the mid 1800s, Arizona and New Mexico were horizontal one north of the other, instead of (like now) vertical and side by side. I've never know why/how that happened.
I read through most of this. I never knew any of it. It seems that Texas and Utah played roles in that shift as well. https://en.wikipedia.org/wiki/New_Mexico_Territory
