The Grand Canyon is one of the natural wonders of the Earth, located in Arizona in the United States.  Erosion caused by the Colorado River, which cuts through the middle of the canyon, has resulted in a majestic canyon and rock formations.  Over the past 17 million years, as the canyon itself was uplifted, the Colorado River and its tributaries etched their way through the canyon and still flow today, exposing much of Earth’s geological history.  When one visits the Grand Canyon, they are literally looking into the past, and seeing the layers of rock from past eras.
