Question

Yellowstone Park

　　Long before any recorded human history in Yellowstone, a massive（巨大的）volcanic eruption spat out a great amount of ash that covered all of the western U.S. , much of the Midwest, northern Mexico and some areas of the eastern Pacific. The eruption lowered that of Mt.St. Helens in 1980 and left a hole 30 miles wide by 45 miles long.

　　That climactic event occurred about 640,000 years ago, and was one of many processes that shaped Yellowstone National Park—a region once said to be“the place where hell bubbles（起泡）up.”Geothermal（地热的）wonders, such as Old Faithful, are evidence of one of the world's largest active volcanoes. These exciting features puzzled the park's earliest visitors, and helped lead to the creation of the world's first national park.

　　Fur trappers'（捕获者）fantastic tales of cauldrons（大锅炉）of bubbling mud and roaring geysers（间歇泉）sending steaming feathers skyward made their way back east. Several expeditions were sent to look into it, opening the West to further exploration and exploitation. In 1871, Ferdinand Hayden led an expedition that included artist Thomas Moran and photographer William H．Jackson. They brought back images that helped convince（使信服）. Congress that the area known as Yellowstone needed to be protected and preserved.

　　In 1872, President Ulysses S.Grant signed a law declaring that Yellowstone would forever be“devoted and set apart as a public park or pleasuring ground for the benefit and enjoyment of the people.”
