Canada
Ancient Caribou Hunting Grounds Located Beneath Lake Huron
It is believed hunters were able to exploit the grounds during the autumn when the caribou are known to be their meatiest. It is also the time of year that their fur is of the best quality. In addition, the configuration of the hunting grounds indicates that it was beneficial for spring hunting when caribous would migrate back into Canada after the winter season. The finding isn’t unique as the ancients widely used this tactic of caribou hunting throughout the Northern arctic regions. What makes this find special is how well it is preserved. The relative calm of the waters in Lake Huron has largely preserved the structures allowing scientists to study them and gain valuable insights.
There is another choke point along the land corridor known as the Alpena-Amberley Ridge that will be further researched this spring. Other members of the research team who are scuba-trained dove to the depths of underwater site to explore it. They were able to retrieve a modest amount of artifacts. An underwater rover is also exploring the hunting grounds and providing feedback via video camera.
