Yellowstone National Park,. Yellowstone National Park is the centerpiece of the Greater Yellowstone Ecosystem, the largest intact ecosystem in the Earths northern temperate zone. Yellowstone became the worlds first national park on March 1, 1872. Located mostly in the U.S. state of Wyoming, the park extends into Montana and Idaho. The park is known for its wildlife and geothermal features; the Old Faithful Geyser is one of the most popular features in the park.,Yellowstone National Park spans an area of 3,472 square miles (8,987 km), 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 the worlds 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.,Hundreds of species of mammals, birds, fish and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Common animals in the park include grizzlies, wolves, and free-ranging herds of bison and elk. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park burned. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobile.,Tourist Map of the Yellowstone National Park,Attractions,老信徒温泉(Old Faithful) 诺里斯间歇泉盆地(Norris Geyser Basin) 巨型温泉(Mammoth Hot Springs) 黄石的大峡谷(Grand Canyon Of The Yellowstone) 黄石江(Yellowstone River) 黄石湖(Yellowstone Lake) 汤姆大叔铁道(Uncle Toms Trail) 巨型山庄(Grant Village) 海顿山谷(Hayden Valley) 嘛山谷(Lamar Valley)西部拇指(West Thumb) 塔式瀑布(Tower Fall),Tower Fall,Yellowstone River,Grand Canyon Of The Yellowstone,Geyser Basin,Mammoth Hot Springs,Sunset Lak
