What Was North America Like During The Ice Age?
The most recent Ice Age occurred in the Pleistocene epoch, a period that started about 2.6 million years ago and ended just 11,000 years ago. During this period, the world, and particularly the wildlife, looked very different.
Much of the continent at the time was buried under the enormous Laurentide Ice Sheet, a mass of ice, miles deep, which extended as far south as Illinois. Alaska, however, remained largely glacier-free, due to a lack of precipitation. As sea levels were much lower, it was connected to Asia via a land bridge known as Beringia, which allowed animals, and eventually humans, to cross between the two continents.
