Rock formations at bottom of Lake Huron show signs of pre-historic hunters, page 1

This isn't a big find or anything, but it is an interesting look at the ancient world and it's drastically different ice-age terrain.

Scientists probe Lake Huron for signs of pre-historic caribou hunters

Guided by computer simulations that reconstruct a lost world now lying at the bottom of Lake Huron, a team of scientists is preparing to search this spring for ancient artifacts along an underwater ridge that straddles the U.S.-Canada border — a place the researchers believe was a caribou-hunting hot spot about 10,000 years ago for some of the earliest inhabitants of North America.

University of Michigan researchers first announced in 2009 that they'd discovered rock formations along the drowned ridge that appeared eerily similar to well-documented caribou-hunting structures used in prehistoric times by the "Paleo-Indian" peoples who once occupied Canada's Arctic and sub-Arctic territories.

"Lines of rocks were traditionally used by ancient aboriginals to create "drive lanes" to steer migrating caribou toward "kill sites." There, spear-wielding hunters would hide behind strategically situated hunting blinds — piled walls of stone — before rising to fling their weapons at the passing herd.

But after almost 10 millennia at the bottom of Lake Huron, the unusual rock formations found in 2009 constitute "promising" but not definitive evidence of an ancient hunting culture, University of Michigan marine engineer Guy Meadows told Postmedia News on Tuesday. That means scanning the lake floor for more telling traces of a prehistoric human presence, such as fire pits, toolmaking sites and other hunting structures."

The rock "drive-lane" formations were made so as to herd the caribou to a narrow point where they could be picked off by hunters hidden by stacks of rocks.
