How the Earth Was Made (2009)

S02E01 Grand Canyon

Stretching nearly 300 miles in length and plunging over a mile deep, the Grand Canyon is so immense that four Empire State Buildings stacked end to end wouldn’t reach its rim. Massive tectonic plates collide and grind, forcing a colossal plateau more than a mile upward. The Colorado River, flowing down from the Rocky Mountains and heavy with sediment, has tirelessly carved this breathtaking chasm through the ever-rising landscape.
