Yellowstone National Park - 黃石公園

黃石國家公園 （Yellowstone National Park） 是世界第一座國家公園，成立於1872年。黃石公園位於美國中西部懷俄明州的西北角，并向西北方向延伸到爱达荷州和蒙大拿州，面积达7988平方公里。这 片地区原本是印地安人的聖地，但因美國探險家路易斯與克拉克的發掘，而成為世界上最早的國家公園。它在1978年被列为世界自然遗产。

園 內高度從北方入口（蒙大拿州的伽德納（Gardiner））的5,314尺上升到公園東南方最高點的鷹峰（Eagle Peak）的11,358尺。在黄石公园广博的天然森林中有世界上最大的间歇泉集中地带，全球一半以上的间歇泉都在这里。这些地热奇观是世界上最大的活火 山存在的证据。黄石公园以熊为象征。园内约有200多只黑熊，100多只灰熊。

Yellowstone National Park became the world's first national park on March 1, 1872. Located mostly in the U.S. state of Wyoming, the park extends into Montana and Idaho. Yellowstone National Park spans an area of 3,472 square miles (8,987 km²), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is the largest high-altitude lake in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered an active volcano; it has erupted with tremendous force several times in the last two million years. Half of the world's geothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park burned.
