I took those stressed-plastic (topography) quad sheets for the southern U.S. and shined a sharp, oblique spotlight.
One fellow told me to make an expedition to the (apparent, presumed) rebound cone and look for shattercones, but that's a bit much for an old guy like me.
RATS! My image is 1.2 megs, I'll add the post in the AM. A link is here
EDIT OK here is the image. The rebound cone is called Paynes Mountain, and Pack Mountain, a little east of Copperhill TN.

I don't know about that. Copper's not really an abundant meteoritic material AFAIK; it's not one of the direct stellar fusion products for sure, like iron is.

Big smacks makes big cracks. Then hot groundwater circulates around and emplaces lots of neat metal ores.

For example, the Vredefort impact structure directly affected the evolution of the Witwatersrand Basin, which is responsible for "half the world's gold output since its discovery over 100 years ago". (50,000 tons of gold)

The Sudbury impact structure in North America has produced over $120 billion in Cu and precious metal ores.

(Like pre-impact Vredefort and post-impact Sudbury, Western North Carolina has had extensive metamorphism and folding)

So is "folding" the more accurate name, in my third Google-view above, for the "striations" in Eastern Tennessee, the "Hatfield and McCoy" territory running from Chattanooga to Knoxville?
And does the concentric bend they make around my "crater" demonstrate support for the crater idea?
Here's a wider view, Chattanooga in the foreground to Knoxville in the distance (state boundaries in white), that shows the relationship I'm asking about.

That's the same orange circle in my other Google-views; it probably is not the precise same circle in my stretched-plastic views.
Here is a view from Sudbury Structure (did I pick the correct one?) to Copperhill (again with my orange circle).


Oh, and by the way, Juramike, MasterCard really oughta produce the promo you suggest.
