"There's two components to the site," Weiser said. "One's a historic component, which was a brickworks that dated from the 1850s to 1905. And there's the prehistoric component -- the upper portion of the site was largely disturbed by the brickworks, but what we found intact was from maybe the time of Christ back 7,000 years."
Archaeologists said the site was frequently flooded, leaving behind "time capsules" because new soil sealed off the older surface and items left by the people who had used it. About 7,500 years ago, the ground surface would have been about 14 feet lower than it is now, experts said.
Interesting, considering the time element dates back to the time of Christ. It is hard to imagine North American civilization and their livelyhoods, prior to the last couple of hundred years.
Very interesting.
