How Was The Grand Canyon Formed?

Description:  The Grand Canyon is a mile-deep and was carved by the Colorado River over millions of years. This phenomenon shows how consistent weathering and erosion over a long period of time can radically shape the earth. Even though the work of the Colorado took millions of years this is relatively rapid compared to the billions of years of deposition revealed by the Canyon. A trip down into the Grand Canyon is literally a trip back in time written in the rocks.
