Mighty, elemental forces molded North America—fiery eruptions, titanic floods, the grinding of great ice sheets, and massive impacts from space all shaped our homeland. This film unfolds in a forgotten world that existed long before our own, crossed by long-lost mountain ranges, deserts the size of Africa, and vast inland seas spanning the length of the continent. Explore beloved landmarks like the Grand Canyon and Niagara Falls from the inside out as we witness the clash of nature’s creative and destructive forces. This spectacular road trip through a tumultuous deep past explores three fundamental questions: How was the continent built? How did life evolve here? And how has the continent shaped us?
