The Grand Canyon in Arizona, USA is one of the world's most iconic natural attractions. The canyon covers about 2,000 square miles and is nearly 300 miles long. It is up to 18 miles wide and 5,000 feet deep in places. The Grand Canyon has been shaped by the Colorado River, which has cut down through layers of rock for over a million years. Much of the edge (rim) of the canyon is inaccessible desert. The two major locations at which visitors can access the canyon are the South Rim and North Rim National Parks. The North Rim is over 8,000 feet above sea level. This means that the area receives a large amount of snowfall in winter, so is closed for up to 6 months of the year. The South Rim is lower (about 7,000 feet above seal level) and so is open all year round.
