A 9,000-year-old hunting site at the bottom of Lake Huron reveals seasonal approaches to hunting by early humans
Ancient caribou hunters were also apparently great architects.
A 9,000-year-old underwater hunting site discovered by scientists at the Alpena-Amberley Ridge beneath modern Lake Huron shows an elaborate
arrangement of limestone rocks and artifacts used for hunting caribou. Back then, the ridge was a piece of dry land that connected northeast
Michigan to southern Ontario.
The submerged site consists of a stone lane where limestones are arranged on either side, running parallel to each other. The lane is funnel-shaped
that's broad in the beginning before narrowing down.
The stones are arranged in a line, exploiting caribou's strange fascination with linear landscape, says John O'Shea, the Emerson F. Greenman Professor
of Anthropological Archaeology at the University of Michigan and lead author of the study. The lane, dubbed "Drop 45 Drive Lane," has a dead-end,
where most of the animals were hunted down. The stones alongside the lane were used for concealment.
In addition, outside the lane, three circular hunting blinds were built to further conceal the hunters and approach the animals.
The historical site has been preserved so well underwater that O'Shea compares the site to Pompeii. Had this site been situated on land, it would
have become very difficult to preserve, as it could have been destroyed from activities such as farming -- even before archaeologists would have found
it. This study emphasizes the importance of carrying out archaeological investigations of submerged prehistoric landscapes.
Ancient Caribou Hunting Site Discovered Beneath Lake Huron
Researchers based at the University of Michigan think the roughly 9,000-year-old-structure helped natives corral caribou herds migrating
across what was then an exposed land-corridor — the so-called Alpena-Amberley Ridge — connecting northeast Michigan to southern Ontario. The area
is now covered by 120 feet (347 meters) of water, but at the time, was exposed due to dry conditions of the last ice age.
