Being a non-native American, I only have tangential knowledge of the map, although that somehow plays somewhat to my advantage as it also immerses me into the environment as Humans have all but forgotten civilization before the cataclysm. I shall start getting to work on an application, though I am a little bit challenged in terms of creating a nation from this as the post apocalypse is no laughing matter, perhaps I shall make a theocracy, I'm sure the humans who have made their return would most likely see the remains of civilization and the Machines that they've built and mistake it as the work of Gods, for now I just need to conceptualize, I'll get an application up soon.

For what I can offer per geography, since that's what would matter in this world: The region of New England (North-east United States, above the state of New York) is predominately rocky and hard to farm. Not to say it's impossible since the region has been farmed for centuries and farmers made proper fortune there since they were otherwise close to major ports like Boston (now gone completely). Agriculture in the area left when the Eerie canal was dug connected the Atlantic with the Great Lakes which meant mid-western farmers in the states of Ohio, Indiana, and Michigan and points further could more readily get crops and commerce to the outlet to the great shipping lanes of the coast without anything spoiling or making the adventure more complicated than it was worth.

Not everything culturally though would be totally forgotten, I can grant leniency on the matter of material passing into oral history and some androids passing down information otherwise lost, as they would have in other fields appropriate for the current constraints of civilization.

The Appalachians extend for the most part from the very northern north-east down through the south into Georgia (at this point I'm going to say if all else, you'll Google the states to see where they are). Here's a handy map of the subdivisions of the range in the north:

The Appalachians going south through and passed Pennsylvania can be hard and craggy enough that it would more than likely house and keep semi-isolated various communities or pockets of people. The Appalachians come Virginia, Kentucky, Tennessee and on down are known for being religious in the Christian since and have had their own brand of mystical quasi-shamanistic interpretation with snakes.

The southern coast is defined by bayous (swamps), and depending on how things may go in the region in the future-world pre-war may or may not now be conquered by kudzu, which was imported over from Japan and then let go wild when people didn't know what the hell to do about it.

Michigan in the south is a lot of soft rolling hills, and the Upper Peninsula has always been poor and depopulated and I could easily say would be one of the least effected places, like with the states passed the Mississippi.
