The Grand Canyon in Colorado, U.S.A is a series of huge gorges ‘dug out’ bu the waters of the Colorado River shushing through a narrow tract joining Little Colorado to Lake Mead.
Over 2,000 meters deep, up to 25 kilometers wide and 450 kilometers long, the Colorado began this canyon five or six million years ago. And as well as tourists, it attracts the adventurous types who ride down it in rubber dinghies.
