Out there in the western prairie, Rocky Mountain Front immediately to our west. The Great Rolling Prairie a thousand miles to our east. And right there where the two meet, here's the corridor. That was the ice-free corridor where animals and people undoubtedly passed. I'm not necessarily saying that that was the corridor that provided the pathway for the peopling of America. But I think for a certain, for a period of time, it certainly was a place of migration and even occupation. Maybe in that interval between the beginning of the Balling, right, around 15, and the beginning of the Younger Dryas.
