I was wondering if anyone had or knew of a North American map in the fallout universe. I was hoping to see some cities that might still be there as well as territory lines such as the NCR, the brotherhood, etc.

We can only guess what the territory lines are, but we are given some pretty good clues.

It would be nice to have an official thing though.

This is how I think the US looks as of 2281. (I forgot to get rid of the Khan Empire, so pretend it isn't there.)

We aren't 100% sure on Ronto (I think it could either be the Canadian city, or the Ohio city 30 miles away from Pittsburgh), Crater Banks (I assumed it was the outer banks in North Carolina), The Great Lanta (I'm saying Atlantic city as Father Clifford says it is a coastal city), and The Erie Stretch (I just made a line of the Erie Canol, but it could be Cleveland or something).
