Next time on Making North America. This
is not the easiest thing in the world.
10,000 years ago, our continent was
locked in ice. So, how did we get here?
It's hard to imagine somebody crossing
even one ice field like this. What
challenges did we face? And how did we
turn the rocks of our homeland into
riches? This thing is phenomenal.
Making North America on Nova.
