A steep gorge by the Colorado River, Arizona in the United States, the Grand Canyon has some truly enjoyable scenery. It is 277 miles in length, 4 to 18 miles in width, and about a mile deep. Scientists believe that the canyon was created by the Colorado River over a six million year period.
Native Americans built settlements in the caves within the canyon before the emigration of Europeans. It was also considered to be a site of pilgrimage by the Pueblo people. The first recorded visit to the Grand Canyon by the Europeans was in 1869. Although it is not the deepest canyon in the world, it is known for its extremely large size and beautifully intricate landscape. The Grand Canyon National Park is said to be one of the first national parks in the United States and it attracts more than five million visitors a year. Weather conditions in the Grand Canyon vary greatly between seasons as well as varying at different elevations. While winter snow is experienced by the higher forested rims, the inner gorge has a desert temperature because of the low elevation.
