The truth of the matter is, I don't know enough about the subject to even ask the right questions. The only thing that seems to make any sense to me assuming the last study I posted is more or less correct, which indicates little uplift along the South Carolina coast, is the bays would HAVE to be ~120,000+ years old to have been formed by sea level changes. That's the last time sea levels were as high as they are now. Question is, is that possible given what you know about the bays?

BTW, taking another look at the sea level table in #220, it looks like I missed the ~70,000 year old sea level by a bit. It looks closer to ~200 - 250' lower at that time instead of the ~150' I originally guesstimated. Do you get approximately the same numbers???

I'm probably missing something. Seems lately when I sit down to look at this mystery, I'm already tired and have difficulty focusing for very long.

That isn't the last time they were "as high as they are now". They were higher 7000 to 5000 years ago, for example. Your graph is probably a rolling 1000-year average or something like it. If you could view it year-by-year, it would be a lot more erratic.
