Geography The Grand Canyon Formation
The Grand Canyon formed over 5-6 million years as the Colorado River carved through rock layers revealing 2 billion years of Earth's history. The canyon reaches 277 miles long, up to 18 miles wide, and over a mile deep. Each rock layer tells stories of ancient seas, deserts, and mountains, making it a geological time machine.
