Well, take solace in the fact that it's unique. Concentric rings and all.

We have a shallow water impact crater that now is dry-land. It is in Wetumpka, Alabama. Shocked quartz and all. Took forever to get it recognized.

Did I say that our summer cottage is located about 20 km from two impact craters (Karikkoselkä (http://www.unb.ca/passc/ImpactDatabase/images/karikkoselka.htm) and Keurusselkä (http://www.unb.ca/passc/ImpactDatabase/images/keurusselka.htm))? :D

Well, I guess that 1800+ million years old bedrock helps little preserving those scars.

In a paper published in Nature on 1st August 2002, Stewart and Allen described the structure produced by an impact that occurred in a shallow sea 60 to 65 million years ago, 140 Km east of where Scarborough is now. Silverpit is buried by up to 1Km of Tertiary sediments which have preserved the fine detail of the structure. This is unusual for terrestrial craters, most of which are at the surface and subjected to erosion.

Interesting time frame for the impact... Not to imply a direct relation to the big one 65 million years ago, since 5 million years is a LONG timeframe, but still interestingly close. Maybe a one-two punch?

I want a nearby impact crater! :x

Preferably a preexisting one, or maybe a little new one that isn't too nearby. :wink:

I live near one, not that I can see much of it with the Chesapeake Bay sitting on it.
