I meant to reply to your post yesterday but got sidetracked somehow -- happens all the time. But yes, I have noticed the same feature you have and it's a curiousity of sorts. Some unusual colors in parts of it in places. If it's the same feature we're talking about, Montgomery Alabama sets right in the middle of a part of it, no?
Best guess is that it's an artifact left over from the uplift of the Appalachians. Pure guess though.
That's right.

I've considered that, but I would have expected such an artifact to be much more linear.
