Human history in the region goes back more than 11, years. The earliest intact archeological deposits in the park were discovered at a site on the shore of Yellowstone Lake. Yellowstone is a supervolcano. The first major eruption of the Yellowstone volcano occurred 2.
That's among the largest volcanic eruptions known, and marks Yellowstone as a supervolcano a term used to describe any volcano with an eruption of more than cubic miles of magma. With the U. Geological Survey and University of Utah, the National Park Service established the Yellowstone Volcano Observatory in to monitor volcanic and seismic activity in the area. Yellowstone is home to the largest concentration of mammals in the lower The list of mammals includes grizzly bears, wolves, lynx, fox, moose and elk.
After losing his horse and most of his supplies, the year-old spent over a month surviving on thistle and enduring snowstorms, delirium and a painful scalding from a hot spring. By the time he was finally found alive in October , he weighed just 90 pounds and was suffering from frostbite so severe that it had worn his feet to the bone.
The system is still considered active and contains a reservoir of magma big enough fill the Grand Canyon several times over. While scientists are not concerned about an eruption occurring any time soon—the last was some , years ago—the volcano is powerful enough to potentially shroud much of the continental United States in ash.

He entered the park at least twice during five years in office—as part of the Hayden Expedition and to evict a squatter in Langford did what he could without laws protecting wildlife and other natural features, and without money to build basic structures and hire law enforcement rangers.
Philetus W. Much of the primitive road system he laid out remains as the Grand Loop Road. Through constant exploration, Norris also added immensely to geographical knowledge of the park.
To reassure the public that they faced no threat from these conflicts, he promoted the idea that Native Americans shunned this area because they feared the hydrothermal features, especially the geysers. This idea belied evidence to the contrary, but the myth endured. Norris fell victim to political maneuvering and was removed from his post in He was succeeded by three ineffectual superintendents who could not protect the park. Even when ten assistant superintendents were authorized to act as police, they failed to stop the destruction of wildlife.
Poachers, squatters, woodcutters, and vandals ravaged Yellowstone. In Congress refused to appropriate money for ineffective administration. The Secretary of the Interior, under authority given by the Congress, called on the Secretary of War for assistance. The Army strengthened, posted, and enforced regulations in the park. Troops guarded the major attractions and evicted troublemakers, and cavalry patrolled the vast interior.
The most persistent menace came from poachers, whose activities threatened to exterminate animals such as the bison. In , soldiers arrested a man named Ed Howell for slaughtering bison in Pelican Valley. The maximum sentence possible was banishment from the park. Its editor, renowned naturalist George Bird Grinnell, helped create a national outcry. This law is known as the Lacey Act, and is the first of two laws with this name. Moreover, each of the 14 other national parks established in the late s and early s was separately administered, resulting in uneven management, inefficiency, and a lack of direction.
National parks clearly needed coordinated administration by professionals attuned to the special requirements of these preserves. It is the world's first National Park. The highest point in the park is 11,' at Eagle Peak and the lowest point in the park is 5,' at Reese Creek. Yellowstone is larger than the states of Rhode Island and Delaware combined. Yellowstone has to earthquakes annually. There are more than active geysers There are more than waterfalls.
