Random Fact: The Grand Canyon
The Grand Canyon is 227 miles long, up to 1 mile deep in some parts and has a width of 18 miles. On 11 January 1908, it was designated a National Monument and then it became a World Heritage Site on 24 October 1979. In a list compiled by CNN in 1997, it was considered one of the Seven Natural Wonders of the Earth, along with Rio de Janeiro’s harbour. However, the Grand Canyon isn’t the deepest canyon in the world – that title goes to the Kali Gandaki Gorge in Nepal.
