Grand Canyon. View over the North Rim of the canyon of Bright Angel Canyon. The Grand Canyon is the world's largest gorge. It formed as the Colorado River eroded down through uplifting beds of soft sedimentary rock. It is over 440 kilometres long and in places is over 1.5 kilometres deep. The oldest rocks,exposed at the bottom of the canyon,are some two billion years old | |
