The epic 3 billion-year story of how our continent came to be. From the palm trees that once flourished in Alaska to titanic eruptions that nearly tore the Midwest in two, we discover how forces of almost unimaginable power gave birth to North America.

How did life emerge on our continent? Why was North America home to so many iconic dinosaurs? And how did a huge sea filled with giant marine reptiles end up covering Kansas?  We tell the story of life and landscape in North America.

From the gold rush to the oil boom, the hidden riches of our landscape have helped Americans prosper. But as our cities grow, so do the risks of catastrophic natural disasters, such as the supervolcano under Yellowstone that could one day obliterate half the continent.
