The rocky mountains, a vast and rugged range stretching across north america, were formed by powerful tectonic forces that have shaped the continent over millions of years. Through the study of fossils, geological layers, and the movement of tectonic plates, scientists have uncovered the dramatic history of these peaks, from their ancient origins on the sea floor to their ongoing transformation by erosion and volcanic activity. This documentary explores the geological processes that built the rockies and the ongoing forces that continue to shape them today.
