I have always been fascinated by impact craters. Also by history. When I was snooping around for references to the era when the Greeks dominated Mediterranean culture, I ran across this map:

The shape of the Aegean Sea surrounding the Cyclades Islands off the coast of Greece was very intriguing. I went search for images of the area and found this one. It's on a very nicely done personal travel site named
Milos Is For Lovers, but it's a satellite photo.

If I'm seeing what I think I'm seeing, it would appear that the Cyclades are the peaks of a central cone in a very large impact crater that made the Aegean Sea. The crater rim looks like to goes around Crete, Karpathos, Rhodes, through Turkey, across the Dardenelles, and back around down the spine of Greece. Now I'm wondering if maybe the Sea of Marmara and maybe even the Black Sea were formed in the same event, perhaps by other impactors accompanying the one that made the Aegean.
