Where the first Americans came from, when they arrived and how they got here is as lively a debate as ever, only most of the research to date has focused on dry land excavations. But, last summer's pivotal underwater exploration in the Gulf of Mexico led by Mercyhurst College archaeologist Dr. James Adovasio yielded evidence of inundated terrestrial sites that may well have supported human occupation more than 12,000 years ago, and paved the way for another expedition this July.
As part of their 2008 findings, the researchers located and mapped buried stream and river channels and identified in-filled sinkholes that could potentially help document the late Pleistocene landscape and contain artifacts and associated animal remains from early human occupations. Continued exploration, Adovasio said, will be geared toward assessing a human presence on the now submerged beaches and intersecting river channels.

The First Snowbirds:By the middle of the twentieth century, fluted points like those recovered at Big Bone Lick were viewed by the great majority of the North American archaeologists as the signature artifacts of the first occupants of the New World. Moreover, the makers of these points (now named "Clovis" after their initial occurrence in a stratified context near Clovis, New Mexico) became central players in a highly imaginative peopling scenario called, in recent years, "Clovis-first." According to this paradigm, a small group of migrants crossed the interior of the now-submerged Bering Platform about 12,000 radiocarbon years ago. After a brief sojourn in the unglaciated Bering Refugium, these pioneers were thought to have passed down the ice-free corridor between the Cordilleran and Laurentide ice sheets in central North America, thence across virtually the length and breadth of the entire unglaciated New World, arriving at the tip of South America within a scant 400–500 radiocarbon years or less.

Texas A&M has the best underwater archaeological group in the world. I had a VP that had a degree in War from A&M.
because most of the items predate any 'Native Americans' by several thousand years.
Underwater war? ;’)
Before long they’ll be researching and speculating what happened to that grand civilization know as the American Middle Class. What’s happening today concerns me much more than what happened out in the ocean some thousands of years ago.
They’ll be confused by the discovery of Ted Kennedy’s Olds...
Sea-level rose 330' at the end of the most recent Ice Age.
Do the math, guys...
Well, that has to do with how everything runs downhill, including the water supply. :’)
Yes. That and being on the water’s edge allows you to eat even when the land crops fail.
It’s good to live on a mountain.
My house is 400’ above sea level, and 2 miles from the ocean. I guess I’ll be on an island! COOL!
Clams. YUM!
