I am going to try to compose a coherent response to this reply and your Freepmails into one. I made a promise to myself I wouldn't stay up this late again, but I have spent literally hours trying to piece some things together, and if I don't do it now....

Most indicators tell us the bays themselves are old; maybe very old. One thing that bothers me about them being in excess of say 100,000 years old, is the apparent lack of erosoin of their features. Also, the elevations these things are found in the US and especially other places around the world(which I would like to see you address) all but preclude their being created by sea level fluctuations. BTW, best I could determine, the last time we saw sea levels greater than they are now was ~120,000 years ago. They have more or less steadily risen since then. A relatively crude map but about as good as I could find:

In the absence of shocked quartz...

Do you know if this feature was found at the Tunguska site?

I still maintain that the phenomenon is best explained hydrologically.

While not impossible at elevations of 1500 - 1600 feet(maybe more?) at other sites around the world, there may have been something else at work. Fast melting glaciers? Ice dams giving way? We would maybe find some of these "up north" then? Maybe the great flood was somehow involved???

All's I know is it's way past my bedtime........again!

In the southeastern US, Carolina Bays are found on flat, very stable landscapes. The only erosion on those landscapes is usually wind erosion; bay rims are material, deposited by wind, that was eroded by wind, from somewhere upwind.

Sea level fell during the last glaciation, to a low of about 330 feet below modern sea level. It began rising about 12,500 years ago. Most of the rise took place between 12,500 and 7000 years ago.

For the morning....

Thanks for the reply. I've got to run and will be away from a computer most/all of the day, but I wanted to point out a mis-statement in my last post: While it may have been ~120,000 years since sea levels were the same or greater than they are today, you're right, the rise in fact didn't begin until ~12,000 - 15,000 years ago.

Would you take a crack at a couple of other questions I asked in my last post re elevations, shocked quartz, etc? Gotta run.
