One of the world's natural wonders, The Grand Canyon, carved by the mighty Colorado River, is one of the most spectacular landscapes in the world. There is simply nothing like it. The Grand Canyon is 277 miles (446 km) long, it ranges in width from about a quarter mile to over 18 mi (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters). The Paiute Indian tribe calls the canyon Kaibab, which means "mountain lying down". The Grand Canyon is a UNESCO World Heritage Site that is located entirely in northern Arizona. In my opinion this is one of those places you can spend some time describing but it will never be the same as being there!
