A complex set of 9,000-year-old hunting blinds sit beneath the surface of what is now Lake Huron. Based on the arrangement of the blinds, it appears that the region's ancient hunters and their families cooperated to drive caribou, and possibly other game, into a centralized "kill zone." The discovery, along with other artifacts, provides information about the social and economic organization of the hunters, researchers report April 28 the Proceedings of the National Academy of Sciences.
The find also suggests that other ancient archaeological sites preserved underwater could lead to a better understanding of humans' past, the scientists say.
