The Grand Canyon is one of America's main tourist attractions. It is so big that you must go there yourself to feel its true size and beauty. The Colorado River formed the Grand Canyon over millions of years. Slowly, the river cut down through hard rock. Today, the canyon is one mile deep and 200 miles (320 km) long. It's interesting that there are different kinds of plants and animals on opposite sides of the canyon. The south side is dry and desert country. The north side has tall forests. The canyon looks different at different times of day, and in different seasons and weather. At sunrise and sunset the red, gold, brown and orange clouds of the rocks are especially clear and bright. In winter, the canyon is partly covered with snow, you can walk down into the Grand Canyon, or you can go down flown on the back of a mule. But be careful to carry enough water because inside the canyon, it is very hot much hotter than at the top.
The United States is a young country. Its written history is only a few hundred years old. It is sometimes, in fact called the "New World". Over the last four hundred years millions of people have come to start a new life in this "New World".
Americans are not afraid of new ideas. They built the first skyscrapers. They like to be modern. They like exciting, modern cities, new houses, and new cars. At the same time, Americans love old things. They like to visit historic houses and museums. They build old pioneer houses and remember the days of the "Wild West".Americans are interested in old traditions, but they are good at making new traditions too.
The people of the United States are a mixture of many different nationalities. Every American schoolchild learns that the United States is a big melting pot of countries. In a melting pot, different metals are melted together to make a new metal. The United States is like a melting pot for people. In the past, people from many different countries came to the US and made one country out of many. In one city you can find people whose parents, grandparents or great-grandparents came from China, Africa, South America, Southeast Asia, and every European country. These different people brought to their new land a wonderful mixture of customs and traditions. The Germans brought Christmas trees. The Irish brought St. Patrick's Day celebrations. The Scots brought Halloween.
