Our Corduroy Physiography

We live among 800 miles of corduroy trousers, according to Google Earth. It really is striking; a  ridge and valley physiography that stretches  from Alabama to Pennsylvania, and we, in Oak Ridge, are in the middle of it. The ridges are very long, with few gaps in them. How did they form? Some kind of remnant of tectonically thrusted then folded strata. I'm not sure there's anywhere else in the world quite so  corrugated. Is there?
