>Fathoms beneath present-day Lake Huron, early Americans once stood on dry land, hunting caribou as the animals migrated between southern Ontario and northeastern lower Michigan. >A team led by University of Michigan researchers drew international attention when they announced those findings a decade ago, after discovering rock arrangements indicative of prehistoric hunting camps on a lake bottom ridge. >But far less fanfare has followed the scientists in years since, as they’ve pieced together an increasingly clear picture of life 10,000 years ago in the now-submerged subarctic grassland. >“The thing that’s difficult with this kind of research — and it’s difficult for donors and everyone else to understand — is that it’s a real drudging process,” said John O’Shea, a U-M archaeologist and lead researcher on the project. “You don’t just go out and discover a pyramid, right?” >But gradually, they’ve collected evidence amounting to “an incredible picture that was totally unimagined before we started doing this work.” . .
