1、Probably you have seen photos of the Grand Canyon. But you must go there yourself to feel its size and beauty. The Grand Canyon is one of the greatest natural wonders of the world. The Colorado River made the Grand Canyon over millions of years. Slowly, the river cut down through hard rocks. At the
2、same time, the land was rising. Today the canyon is very deep. Its also very wide, about 20 kilometres. And because of its height, there are different kinds of plants and animals on both sides of the canyon. The canyon(峡谷) looks different at different times of the day and in different seasons and weather. At sunrise, the red, gold, brown and orange, colors of the rocks are especially clear and bright. Whether you see the Grand Canyon from the top or the bottom, it will be a(n) experience that you will never forget.
