（单词翻译）

 As North America emerged from the grip of the last ice age, the door was opened to outsiders for the very first time. As these early immigrants pushed their way south, they found themselves in a land of an unimaginable opportunity, overflowing1 with game mammals, animals with no experience of humans or their weapons.

 
The arrival of these hunters coincided with a time of great change of the plains. Within the next few hundred/ years, many ice age animals vanished forever. So 13,000 years on, how do we know anything about this lost world? There are still clues to be found if you know where to look.
 
In the Bighorn Mountains of Wyoming is a hidden cave recreated here, where over the millennia2 thousands of animals have fallen to their death. Preserved below the surface are bones dating all the way back to the ice age. Remains3 of bison lie alongside antelope4 and rabbit. But they are mixed with those of camels, extinct horses, giant wolves.
