Possible meteorite impact craters in the south-eastern United States. I've counted over 1220 possible sites! I'm still catalogging craters as I find them. I got "tired" and decided not to mark the smaller crater sites. However, you get a picture of the wide-scale devastation that occurred from this (or these) event(s). I actually drove to sites 252 and 253. These two sites are realitvely "small" craters. However, site 252 is impressive!

Some of those are hills , some are farms

Jeffery's correct. If you look at a topo, you'll notice that some of your craters are actually hills. Most of the Florida ones are identified sinkholes and/or springs. A few that I looked at were simple farms built in the inside bend of a river or large creek, making the border rounded.
However, a great many of the ones in the Carolinas are the "Carolina Bays", the origin of which are disputed, so you're as right as anyone on those....they could all be impacts.

No, they are craters. Look again. Because of erosion, many are "filled."

I will acknowledge that I may have marked a "few" hills or sink holes. However, look at the total picture. I would argue that there's a "pattern" that can be easily seen that shows the path of the "explosion" or storm. Site 252 is a "farm" in Wayne County. Guess what, the farmer followed the shape of the terrain. In this case, the "bowl" of the crater. Also, the road curves around the depression that was formed by site 253.
I did make a few more mistakes around craters 666, 669, 661. These are manmade. I did not make a lot of circular sites though. I "sort of" knew these were suspect, so I drove out to them (They are probably 20 miles or so from where I live). I was unaware of anyone using this type of farming technique in Eastern Carolina. I was told by the farmer that this is a method he can use to get rid of animal waste (solid waste) from his pig houses.

Those are Carolina Bays. They are a product of water, not meteors. It is possible that a huge asteroid hitting the ocean was the indirect cause of them, but they are not craters. They have been excavated and there are no extraterrestrial remains there that would be the result of an impact.
What happened was something caused a tsunami a long time ago. This tsunami made the one on 12/26 look like a ripple. There is some evidence that it went as far inland as the foot of the Appalachians at the NC/VA border.
The sandhills, the enormous sandbars in the piedmont, the carolina bays, etc are all evidence of one mind bending tsunami.
I don't know what caused it, but if you look off the east coast you'll see where a giant chunk of the continental shelf has collapsed and sunk down. I'd bet that had something to do with it. Something the size of Massachusetts sinking all at once is bound to have thrown up a lot of water.
When the water retreated it scowered out the bays. If you look at pics of where the tsunami hit asia you can see smaller versions of the bays here and there.
No meteor needed. In fact, meteors don't carve out shallow oval depressions like the bays. They are completely different animals.

Well, we know that water flows along land contours, and I cannot see how it would scour out almost perfect eliptical bays, especially where some bays have overlapped others. I think it is more likely that a shower of comet fragments falling in clusters from the northwest at an angle to the surface might have created the anomalies. Also, I think that fragments from the big impact at Chesapeake Bay would not have formed secondary craters all aligned from the northwest, and in a pattern only from NC to South Georgia.

Show me a shotgun pattern of eliptical craters anywhere else in the solar system.
Water turbulance can do some mighty strange things. If these were craters, there would be irridium dust in them. There would be shocked quartz in the area. The sediments under the bays would be depressed. Instead we don't find any of that. In order to form a crater you have to expend a lot of energy. That energy won't form an oval crater. Not a shallow one that doesn't mess up ones right beside them either. It's just not possible. I'd like there to be half a million small craters to investigate around here. It would be so cool. But that's not the case.
These are simple erosion structures caused by water running off the land after an enormous tsunami. They point in the direction the water was going from/to.
An asteroid might have cause the tsunami, but that's all it did. I lean toward a collapse of the continental shelf about 200 miles off the coast near Savannah, GA. That was a lot of land to go down. It had to have had an effect.

The effort expended here is commendable. As you see from the other replies, the general concensus is that these can not be direct impact craters. The paper A RE-EVALUATION OF THE EXTRATERRESTRIAL ORIGIN OF THE CAROLINA BAYS , discusses the topic.
The subject of "carolina bays" and oriented lakes has been much debated. Perhaps you may be interested in yet-another theory - that these are not impact craters, but the splatter of impact EJECTA . You can see my presentation at Perigee: Zero Carolina bay morphology

I grew up on at site 883. It is definatly a large depression. My grandparents always said it was a crater and it sure has the looks of it. The road follows around the rim of the depression. It is unlike any other Carolina Bay I have seen.
