Prehistoric stone walls were discovered deep beneath the Lake Huron, according to a new findings in Monday’s the Proceedings of the National Academy of Science.
This will give a clearer portrait of prehistorical people’s life in the Great Lakes region, U.S.
The stone walls form a lane 30 meters long and 8 meters wide, and have its hunting blinds built into the sides as well as other lanes and structures, similar to structures used to channel caribou by hunters.
“They were massive, and probably related to the first people to inhabit the New World and hunt mastodons,” said John O'Shea, an archaeologist of Michigan University.
A picture is beginning to emerge of a hunting and gathering people who brought down caribou in small groups in autumns, dug in snug and lived off food caches and animals such as beaver in the winter.
The findings were published Monday in the Proceedings of the National Academy of Science.
