Hidden Civilization Found Under Lake Huron

摘要

Traces of an ancient caribou hunting ground lie buried beneath Lake Huron, according to archaeologist John O'Shea at the University of Michigan. Modern Siberian herders manage reindeer migration by chopping down trees and laying them on the ground, he noted; the animals instinctively follow these "drive lanes." O'Shea has found evidence that Paleo-Americans did the same thing thousands of years ago, when the climate around the Great Lakes was similarly Arctic-like.
