What Did Early Americans Eat?

Old tools provide new evidence

Doug Bamforth had taken calls like this one before.

Besides, it was also the middle of May. The semester was over, and he was about to leave town. But the caller, a bio-tech mogul named Patrick Mahaffy, kept insisting, and the next day Bamforth took a ten-minute walk from his office to the site. What he saw astonished him: right there, in urban Boulder, no fewer than eighty-three stone tools were spread out on a patio table.
