拥有世界上一半地热特征和三分之二以上间歇泉的黄石公园被认为是世界自然宝藏之一。
1872年3月1日，美国总统尤利塞斯·格兰特（Ulysses S.
Grant）签署一项确定黄石公园（Yellowstone）为国家公园的法案，黄石公园因此成为美国第一座国家公园。黄石公园横跨怀俄明、蒙大拿和爱达荷三个州近9000平方公里土地，其面积为罗德岛州的两倍多。
拥有世界上一半的地热特征和[世界]三分之二以上间歇泉的黄石公园也被认为是世界自然宝藏之一。虽然'老忠泉'(Old
Faithful)不是黄石公园内最大的喷泉，但它喷发的频度比其他喷泉都高。这个最受人们喜爱的喷泉之所以赢得此名声是因为它的喷发比公园内其他大的间歇泉都更具有一贯性。老忠泉平均每91分钟喷发一次，在90秒到5分钟期间可喷发32000公升沸腾的水，其高度可达55米。
黄石公园拥有无数其他的自然奇观。 位于黄石公园猛犸区（Mammoth District of
Yellowstone）的猛犸温泉（Mammoth Hot
Springs）展现了地热水冲刷岩层的情景,而黄石湖（Yellowstone
Lake）则是美国海拔2135米以上地区最大的淡水湖。灰熊、狼、猞猁和美洲野牛在园区内自由漫游。事实上，黄石公园是美国公有的最悠久也是最大的野牛群栖居地。

Yellowstone: Wyoming’s Wonderland
14 July 2012 Worth protecting: Wyoming’s Yellowstone
National Park is one of the world’s last intact temperate
ecosystems.
On March 1, 1872, U.S. President Ulysses S. Grant signed a bill to
establish Yellowstone, the nation’s first national park. Spanning
nearly 9,000 square kilometers throughout Wyoming, Montana and
Idaho, Yellowstone is more than twice the size of Rhode
Island.
With half the world’s known geothermal features and more than
two-thirds of the world’s geysers, Yellowstone is also considered
one of the world’s natural treasures.
Although it is not the largest geyser in the park, Old Faithful
erupts more frequently than any of the others. This crowd favorite
earned its name by performing more consistently than the other
large geysers in the park. On average, Old Faithful erupts every 91
minutes, expelling up to 32,000 liters of boiling water over the
course of 90 seconds to five minutes. Old Faithful’s outbursts can
reach up to 55 meters in height.
Yellowstone is home to myriad other natural wonders. Mammoth Hot
Springs, located in the Mammoth District of Yellowstone, showcase
geothermal waters rushing over steplike rock formations; and
Yellowstone Lake represents the largest freshwater lake in the
United States above 2,135 meters. Grizzly bears, wolves, lynx and
bison also roam freely in the park. In fact, Yellowstone is home to
the oldest and largest publicly owned bison herd in the United
States.
