Deep beneath the waves of Lake Huron, researchers may have found evidence of a Paleo-American culture that lived in the Great Lakes region. Archaeologists used sonar and robotic explorers to examine about 28 square miles of the lake bottom, and found what may be the remnants of a caribou hunting ground; they hope further studies will reveal ancient settlements. Says study coauthor John O'Shea:

What is now part of Lake Huron's obscured floor became a dry land bridge between modern-day Presque Isle, Michigan and Point Clark, Ontario when lake levels dipped some 7,500 to 10,000 years ago [Scientific American].
At depths ranging between 60 and 140 feet, researchers found lines of large stones, which may have been "drive lanes" that aided early hunters as they tried ...
