Summary:
- The Grand Canyon in Arizona was formed by a massive landslide that occurred around 6 million years ago, triggered by a meteor impact that created the nearby Barringer Crater.
- The meteor impact caused the ground to shake, leading to a massive landslide that blocked the Colorado River and created a large lake behind the debris.
- Over time, the lake drained, and the Colorado River carved the Grand Canyon through the landslide debris, creating the iconic landscape we see today.
