The Grand Canyon as you've NEVER seen it before

The Grand Canyon is 277 miles long, up to 18 miles wide and attains a depth of over a mile (6,000 feet or 1,800 meters).
Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their
channels through layer after layer of rock while the Colorado Plateau was uplifted. While the specific geologic processes and timing
that formed the Grand Canyon are the subject of debate by geologists,[3] recent evidence suggests that the Colorado River established
its course through the canyon at least 17 million years ago. Since that time, the Colorado River continued to erode and form
the canyon to its present-day configuration.
Awesome pictures of the Grand Canyon.
