Searching 50 miles offshore from Alpena, researchers discovered “drive lanes” — in effect, runways of death that channeled unwitting caribou into the clutches of hidden hunters — and stone hunting blinds where hunters awaited their prey.
“Caribou have a thing for linear features. They like following lines,” said scientific researcher Lisa Sonnenburg of the environmental consulting firm Stantec Consulting Inc. in Hamilton, Ontario. “Line stones up in a row and caribou will follow them. It’s something about how their brains work.”
Today, scientists and shoreline property owners pay close attention to annual fluctuations of Great Lakes water levels, but water levels between 8,350 and 9,000 years ago were unusually low, according to a newly published study by Sonnenburg and John O’Shea, the curator of Great Lakes archaeology at the University of Michigan’s Museum of Anthropological Archaeology.
