YouTube Description
as posted by the channelBetween 15,000–14,500 years ago, the great Laurentide and Cordilleran ice sheets began shrinking, opening a corridor through Canada — the route many believed the first Americans traveled after crossing the Bering land bridge.
But around 12,900 years ago, the warming stopped dead.

Something big hit reset on the Ice Age.
