Hedges essentially restated comments made in October 1865 by acting Montana Territorial Governor Thomas Francis Meagher , who had previously commented that the region should be protected. Others made similar suggestions. An 1871 letter to Ferdinand V. Hayden from Jay Cooke , a businessman who wanted to bring tourists to the region, encouraged him to mention it in his official report of
2494-598: The Henry's Fork Caldera and depositing the Mesa Falls Tuff . Each of the three climactic eruptions released vast amounts of ash that blanketed much of central North America, falling many hundreds of miles away. The amount of ash and gases released into the atmosphere probably caused significant impacts on world weather patterns and led to the extinction of some species, primarily in North America. A subsequent caldera-forming eruption occurred about 160,000 years ago. It formed
2580-594: The Lava Creek Tuff , a welded tuff geologic formation . The most violent known eruption, which occurred 2.1 million years ago, ejected 588 cu mi (2,450 km ) of volcanic material and created the rock formation known as the Huckleberry Ridge Tuff and the Island Park Caldera . A smaller eruption ejected 67 cu mi (280 km ) of material 1.3 million years ago, forming

The Yellowstone Caldera is the largest volcanic system in North America, and worldwide it is only rivaled by the Lake Toba Caldera on Sumatra . It has been termed a " supervolcano " because the caldera was formed by exceptionally large explosive eruptions. The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 37 miles (60 km) long, 18 miles (29 km) wide, and 3 to 7 miles (4.8 to 11.3 km) deep. The current caldera

Under a half-dozen tribes had made seasonal use of the Yellowstone area- the only year-round residents were small bands of Eastern Shoshone known as " Sheepeaters ". They left the area under the assurances of a treaty negotiated in 1868, under which the Sheepeaters ceded their lands but retained the right to hunt in Yellowstone. The United States never ratified
3096-606: The Nez Perce were friendly to the tourists and other people they encountered in the park; some were not. Nine park visitors were briefly taken captive. Despite Joseph and other chiefs ordering that no one should be harmed, at least two people were killed and several wounded. One of the areas where encounters occurred was in Lower Geyser Basin and east along a branch of the Firehole River to Mary Mountain and beyond. That stream

Over the next 22 years, as the army constructed permanent structures, Camp Sheridan was renamed Fort Yellowstone . On May 7, 1894, the Boone and Crockett Club , acting through the personality of George G. Vest, Arnold Hague, William Hallett Phillips, W. A. Wadsworth, Archibald Rogers, Theodore Roosevelt , and George Bird Grinnell were successful in carrying through
3956-478: The early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the U.S. Department of the Interior , the first Secretary of the Interior to supervise the park being Columbus Delano . However, the U.S. Army was eventually commissioned to oversee the management of Yellowstone for 30 years between 1886 and 1916. In 1917,

After the park's official formation, Nathaniel Langford was appointed as the park's first superintendent in 1872 by the Secretary of Interior Columbus Delano , the first overseer and controller of the park. Langford served for five years but was denied a salary, funding, and staff. Langford lacked the means to improve the land or properly protect the park, and without formal policy or regulations, he had few legal methods to enforce such protection. This left Yellowstone vulnerable to poachers , vandals , and others seeking to raid its resources. He addressed
