[X] My Assistant

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 think it's jus great that many people are doing something similar to what Chuck has done, though using different resources.

There have been good airplane and satellite images of most of the land surface of the Earth for many years, but with the advent of something like Google Earth (and similar other products), thousands of people whose only joy is the avocation of finding patterns in things have been searching the globe for impact crater remnants.

IIRC, there have been dozens of impact structures "discovered" (many since confirmed with ground studies) by people working through Google Earth imagery. I mean, talk about being an armchair explorer!

I tried in Google Earth, setting sun shadows very low, but no pattern emerged, probably because contour height is not exaggerated as it is in the stretched-plastic quad sheets.

I fixed your broken quote chuckclark.

...because contour height is not exaggerated...

I don't have Google earth at work but if IRC you can exaggerate the vertical scale if you wish.
