　　Probably you have seen photographs of the Grand Canyon（大峡谷）, the great valley in the desert country of Arizona（亚利桑那州）. But you must go there yourself to feel its true size and beauty. The Grand Canyon is one of the greatest natural wonders of the world.

　　The Colorado River formed the Grand Canyon over millions of years. Slowly, the river cut down through hard rocks. At the same time, the land was rising. Today, the canyon is one and a half kilometers deep and 445 kilometers long. The oldest rocks at the bottom of the canyon are more than one billion years old. The width varies（变化）from about 200 meters to 29 kilometers across. The rim or top of the canyon is about 2 300 meters above sea level on the South Rim, and about 3 000 meters on the other side, the North Rim. As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Rim is a dry desert country. The North Rim has tall forest.

　　The North Rim of the canyon is quieter. It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River. On the way, you go through Navaho Indian land, and a colorful pink desert called“The Painted Desert”.
