VOA慢速英语 游历美国西部四大国家公园

　　(MUSIC)

　　VOICE ONE:

　　Two other national parks in Utah are included on our trip. The first is Bryce Canyon National Park, in southern Utah. The rock formations there are the result of deposits made by ancient lakes and rivers over a period of about twenty million years. The walls and cliffs of Bryce Canyon once were completely covered with water.

　　About two million people visit Bryce Canyon National Park each year. The park reaches a height of more than three thousand meters. It includes more than eighty kilometers of trails for walking. Or visitors can drive a twenty-nine kilometer long road, stopping off at different points to enjoy the colorful formations.

　　These rock formations at Bryce National Park are extremely beautiful. Sunlight makes many of them appear to be the color of fire. Some of the most unusual kinds of rocks in the park are called hoodoos. They are tall and thin, and seem to grow from the canyon floor. Their colors are bright red, orange and yellow. Some of the hoodoos have interesting shapes and names, like Thor's Hammer, the Hunter, and the Wall of Windows. One hoodoo known as the Poodle looks like a poodle dog sitting on top of a long narrow rock.
