 The fact that both horses and mammoths were here suggests these forests weren’t. It seems that, 14,000 years ago, Beringia was a huge expanse of open grassland¹. 

 

This unique habitat of cold, dry grasslands² is known as mammoths’ steppe. But that’s not how the region looks today. So why is it so different? 

 

Fourteen thousand years ago, the climate here was heavily influenced by the vast blankets of ice to the east.
