VOA慢速英语 游历美国西部四大国家公园

　　One of these areas is called the Maze District. This area includes rock art made by people who lived there more than two thousand years ago. Yet many people today cannot see the Maze District because it is so difficult to reach. The area is one of the loneliest and wildest in the United States.

　　Another area of the park is called the Needles. It includes long, thin, red and white rocks that reach high into the air like fingers on a hand.

　　Another interesting formation is called the Upheaval Dome. This is a huge hole about four hundred fifty meters deep and one and one half kilometers wide. It is considered to be the most unusual geologic structure in the area.
