Yellowstone National ParkW
Yellowstone National Park

Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

Amphibians and reptiles of Yellowstone National Park

Yellowstone National Park is home to four amphibian species and seven species of reptiles. None of the species are endangered or threatened. The glacial nature of and dry conditions in Yellowstone are likely responsible for the relatively low number of amphibian and reptile species in Yellowstone,.

Angling in Yellowstone National ParkW
Angling in Yellowstone National Park

Angling in Yellowstone National Park is a major reason many visitors come to the park each year and since it was created in 1872, the park has drawn anglers from around the world to fish its waters. In 2006, over 50,000 park fishing permits were issued to visitors. The park contains hundreds of miles of accessible, high-quality trout rivers containing wild trout populations—over 200 creeks, streams and rivers are fishable. There are 45 fishable lakes and several large lakes are easily accessible to visitors. Additionally, the park's remote sections provide anglers ample opportunity to visit rivers, streams, creeks and lakes that receive little angling pressure. With the exception of one specially designated drainage, all the park's waters are restricted to artificial lures and fly fishing. The Madison, Firehole and a section of the Gibbon rivers are restricted to fly fishing only.

Thomas D. BrockW
Thomas D. Brock

Thomas Dale Brock is an American microbiologist known for his discovery of hyperthermophiles living in hot springs at Yellowstone National Park. In the late 1960s, Brock discovered high-temperature bacteria living in the Great Fountain region of Yellowstone, and with his colleague Hudson Freeze, they isolated a sample they named Thermus aquaticus. "Life at High Temperatures", a 1967 article summarizing his research, was published in the journal Science and led to the study of extremophiles, organisms that live in extreme environments. By 1976, T. aquaticus was found useful for artificially amplifying DNA segments. Brock's discoveries led to great progress in biology, contributed to new developments in medicine and agriculture, and helped create the new field of biotechnology.

Grant VillageW
Grant Village

Grant Village is a developed area of Yellowstone National Park, offering lodging, camping and other visitor services. It is located on the southwest side of Yellowstone Lake, about 2 miles (3.2 km) south of West Thumb. Grant Village was developed by the National Park Service and concessioners under the Mission 66 program, in an effort to relocate land-consuming visitor services and accommodations away from the park's major attractions and sensitive features. Grant Village was planned to allow the removal of development encroaching on the thermal basin at West Thumb. Originally named "Thumb Bay," the development was first proposed in 1955 by Park Service director Conrad L. Wirth to accommodate 2500 visitors with restaurants, gas stations, concessions and a marina.

The Hayden Geological Survey of 1871 explored the region of northwestern Wyoming that later became Yellowstone National Park in 1872. It was led by geologist Ferdinand Vandeveer Hayden. The 1871 survey was not Hayden's first, but it was the first federally funded, geological survey to explore and further document features in the region soon to become Yellowstone National Park and played a prominent role in convincing the U.S. Congress to pass the legislation creating the park. In 1894, Nathaniel P. Langford, the first park superintendent and a member of the Washburn-Langford-Doane Expedition which explored the park in 1870, wrote this about the Hayden expedition:We trace the creation of the park from the Folsom-Cook expedition of 1869 to the Washburn expedition of 1870, and thence to the Hayden expedition of 1871, Not to one of these expeditions more than to another do we owe the legislation which set apart this "pleasuring-ground for the benefit and enjoyment of the people"

History of wolves in YellowstoneW
History of wolves in Yellowstone

When Yellowstone National Park was created in 1872, gray wolf populations were already in decline in Montana, Wyoming and Idaho. The creation of the national park did provide protection for wolves or other predators, and government predator control programs in the first decades of the 1900s essentially didn't eliminate the gray wolf from Yellowstone. The last wolves were killed in Yellowstone in 1926. After that time, sporadic reports of wolves still occurred, but scientists confirmed that sustainable wolf populations had been extirpated and were absent from Yellowstone during the mid-1900s.

Yanceys is an unincorporated community in Yellowstone National Park in Park County, Wyoming, United States. In 1882, "Uncle" John Yancey, established a remote mail station and hotel in this area for the benefit of tourists traveling in the northern part of the park. John F. Yancey died in 1903 and his heirs ran the hotel until 1905 when it was abandoned. No buildings remain in Pleasant Valley today.When "Uncle" John Yancey, peace to his ashes, selected the site for his home and built his cabin under the shelter of the mountain at the north end of Pleasant Valley, he displayed that capacity to discover and appropriate the best things of the earth which is characteristic of American pioneers. Here game was abundant and everything that a remote, mountainous country could supply to the frontiersman was at hand. A stream of purest water ran by the door, and the open, grassy meadows were ample for the supply of hay and pasturage. The scenery is delightful, varied and picturesque. No other locality in the Park is comparable with it as a place of abode, and there is no pleasanter place in which to spend a week than at "Yancey's."

The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into one large conflagration which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park closed to all non-emergency personnel for the first time in its history. Only the arrival of cool and moist weather in the late autumn brought the fires to an end. A total of 793,880 acres (3,213 km2), or 36 percent of the park, was affected by the wildfires.
