Yellowstone National Park became the world's 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; Old Faithful Geyser is one of the most popular features in the park. Yellowstone is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining, nearly-intact ecosystem in the Earth's northern temperate zone..
Native Americans have lived in the Yellowstone region for at least 11,000 years. The region was bypassed during the Lewis and Clark Expedition in the early 1800s. Aside from visits by mountain men during the early to mid-1800s, organized exploration did not begin until the late 1860s. The U.S. Army was commissioned to oversee the park just after its establishment. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than 1,000 archaeological sites.
Yellowstone National Park spans an area of 3,472 square miles (8,987 km²), 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 world's 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. Grizzlies, wolves, and free-ranging herds of bison and elk live in the park. 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.
Shoshone National Forest is the first federally protected National Forest in the United States and covers nearly 2.5 million acres (10,000 km²) in the state of Wyoming. Originally a part of the Yellowstone Timberland Reserve, the forest was created by an act of Congress and signed into law by U.S. President Benjamin Harrison in 1891. There are four wilderness areas within the forest, protecting more than half of the managed land area from development. From sagebrush plains through dense spruce and fir forest to craggy mountain peaks, Shoshone National Forest has a rich biodiversity rarely matched in any protected area.
Three major mountain ranges are partially in the forest: the Absaroka, the Beartooth and the Wind River Range. Yellowstone National Park forms part of the boundary to the west; south of Yellowstone, the Continental Divide separates the forest from its neighbor, the Bridger-Teton National Forest, to the west. The eastern boundary includes privately owned property, lands managed by the U.S. Bureau of Land Management and the Wind River Indian Reservation, which belongs to the Shoshone and Arapahoe Indians. Custer National Forest along the Montana border is the boundary to the north. The Oregon Trail, the 19th-century covered wagon route, passes just south of the forest, where broad and gentle South Pass allowed the migrants to bypass the rugged mountains of the forest. All of the forest is a part of the Greater Yellowstone Ecosystem, an unbroken expanse of federally protected lands encompassing an estimated 20 million acres (81,000 km²).
The Yellowstone fires of 1988 together formed the largest wildfire in the recorded history of Yellowstone National Park, USA. Starting as many smaller individual fires, the flames spread quickly out of control with increasing winds and drought and combined into one large conflagration, which burned for several months. It was finally extinguished by moist weather in the late fall. A total of 793,880 acres (3,213 km²), or roughly 36 percent of the park was affected by the wildfires.
Thousands of firefighters fought the fires, assisted by dozens of helicopters and airplanes which were used for water and fire retardant drops. At the peak of the effort, over 9,000 firefighters were assigned to the park. With fires raging throughout the Greater Yellowstone Ecosystem and other areas in the western United States, the staffing levels of the National Park Service and other land management agencies were inadequate to the situation. Over 4,000 U.S. Military personnel were soon assisting in fire suppression efforts. The fire fighting effort cost $120 million. No firefighters died while fighting the fires in Yellowstone, though there were two fire-related deaths outside the park.
The Yellowstone fires of 1988 were unprecedented in the history of the National Park Service, and many questioned existing fire management policies. Media accounts of mismanagement were often sensational and inaccurate, sometimes wrongly reporting that most of the park was being destroyed. While there were temporary declines in air quality during the fires, no adverse long-term health effects have been recorded in the ecosystem. Contrary to initial reports, few large mammals were killed by the fires, though there has been a reduction in the number of moose which has yet to rebound. Losses to structures were minimized by concentrating fire fighting efforts near major visitor areas, keeping property damage down to $3 million.Portal:Wyoming/Selected article/5
