If the Wando was laid down(by marine sediment???) ~70,000 years ago, how is it possible it's not presently underwater? From an earlier post:
As you can see, based on this crude chart, sea levels ~70,000 years ago were ~150' below current sea levels. IOW, the Wando should be part of the continental shelf now. A little help?
I don't know what the source of this graphic is (and I would appreciate knowing...it's a good graphic). I scrolled through all 220 replies to this thread and didn't see it. I can only guess that this refers to a global average of sea level, and doesn't take into account local effects of tectonism, glacial forebulge, etc. There has been considerable uplift, relative to global average sea level, just in the last 30,000 years, in my area of Southern Maryland, for example (if you remind me during the work week next week, I'll send you some information on this if you are interested).
