Are there any rural areas of the USA that physically look much the same way they did in the 1700s?

I currently live in Southern Arizona and as much as people refer to it as the desert, I can tell you there are hundreds and hundreds of square miles of desert, high desert, and forest lands that look exactly like they looked hundreds of years ago. although I don't have a lot of in depth experience in travel through New Mexico, Utah, Nevada, Montana and Texas, I can attest to the fact that all these states have some very rural unchanged landscape dating back a couple of centuries.. You need to get out of that cave and explore the country you live in:)
