It sounds like a prehistoric epic, made into a Hollywood movie. Nearly 10,000 years ago, the bottom of Lake Huron was dry land. Stone-Age hunters stalked herds of caribou here.
How do we know this? NewScientist.com tells us:
Scientists sonar-imaged the floor of Lake Huron and found snaking human-built structures. John O’Shea and Guy Meadows of the University of Michigan say that when the huge Laurentide ice sheet melted and flooded the basin, it potentially preserved intact Native American sites – which are rare in the Great Lakes region.
The sonar images reveal a rocky topography with cliffs and dead-ends that would have been ideal for posting lookouts and ambushing migrating caribou.
The scans also show some structures which the two scientists believe are human-made. A line of large rocks, sometimes arranged one upon the other, form a long parapet. At the end of the parapet are boulders, seemingly pushed together into several piles.
Now, these rock arrangements – they look remarkably similar to the hunting drives and blinds that Inuits currently use – and have used – in the Canadian Arctic for hundreds of years. The parapet, or “drive”, helps guide the animals towards archers hiding behind the groups of boulders, or “hunting blinds”. It’s an amazing find of native North American cultural continuity. There’s more here.
This is the sort of discovery we at Travel Dynamics International really like. That’s why we’ve invited Scott Demel, a Great Lakes archaeologist with Chicago’s Field Museum, to join us on our Great Lakes cruise from July 18-25. He’s extensively researched the Archaic prehistory of the Great Lakes region (9,000-2,500 years ago), a really fascinating epoch: the Laurentide ice sheet melted about 8,000 years ago, creating the Great Lakes.
