Archaeologists have found a 9000-years-old caribou hunting drive lane in the Lake Huron.
According to the researchers at the University of Michigan's Museum of Anthropology, the main feature of hunting site called "drop 45 Drive Lane" is the most elaborate structure in the aera.
The ancient site was found 121 feet under water, about 35 miles southeast of Alpena. According to the researchers, the region was once a strip of dry land that connected Northwest Michigan to southern Ontario.
The hunting drive was made of limestone and had two parallel lines of stone leading to a dead-end. The drive even had circular hunting blinds that were built to obstruct the movement of the caribou.
