A hundred feet below the surface of Lake Huron, on a wide ridge that was a land bridge 9,000 years ago, researchers have found the first evidence of human activity preserved beneath the Great Lakes.
The researchers located what they believe to be caribou-hunting structures and camps used by the early hunters of the period.
“This is the first time we’ve identified structures like these on the lake bottom,” said John O’Shea, curator of Great Lakes Archaeology in the Museum of Anthropology and professor in the Department of Anthropology. “Scientifically, it’s important because the entire ancient landscape has been preserved and has not been modified by farming, or modern development. That has implications for ecology, archaeology and environmental modeling.”
