Perhaps no landscape on Earth is as surprising to the observer as the vast face of the Grand Canyon. It is not just a simple canyon but rather a whole maze of canyons, fissures and gorges worn into the rock with unusual buttes, mesas and rock spires standing between them. The exposed multicolored sedimentary layers take on varying hues as the angle of the sun and shadow change throughout the day. It is truly one of the great natural wonders of the world.
