Yellowstone National Park

 

Description of Yellowstone National Park

Location: Wyoming, Idaho, Montana    Map

Area: 2,219,791 acres (898,318 ha)

Yellowstone National Park is an international biosphere reserve, a UNESCO World Heritage Site, the world's first national park (founded March 1, 1872). It is located in the USA, in the states of Wyoming, Montana and Idaho. The park is famous for its numerous geysers and other geothermal objects, rich wildlife, and picturesque landscapes. The area of the park is 898.3 thousand hectares (8983 km²).

According to archaeological data, people began to live in the area occupied by the park 11,000 years ago. Modern researchers first appeared in the region in 1805 (members of the Lewis and Clark expedition), but until the 1860s no economic or scientific activity was carried out here. In the first years after the appearance of the park, he was under the control of the US Army, and in 1917, management was transferred to the National Park Service, created two years earlier.

On the vast territory of the park there are lakes, rivers, canyons and caves. Yellowstone Lake, one of the largest high-altitude lakes in North America, is located in the center of the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered a dormant supervolcano; it has erupted with tremendous force several times over the past two million years. Most of the park is covered with solidified lava; The park contains one of the five geyser fields in the world.

About two thousand species of plants grow in the park, several hundred species of mammals, birds, reptiles and fish, including endangered ones, are found. Most of the territory is covered with forest, the smaller part is covered with steppe. Wildfires happen every year; about a third of all forests burned out as a result of the catastrophic fires of 1988. Several hundred kilometers of asphalt roads have been laid in the park, through which visitors can access. There are numerous opportunities for active recreation.

 

Sights

Yellowstone Upper Falls

Yellowstone Upper Falls is arguable one of the most beautiful waterfalls of Yellowstone National Park. Most of tourists view Yellowstone Upper Falls from natural lookouts at a distance. Few visitors, however, realize that there is a trails that allows you to climb the cliffs that allow you admire Upper Falls from up close. Additionally from here you can see the Second Yellowstone Upper Falls.

 

Grand Geyser

Most hot springs and geysers are located in the valley of the Upper Geyser Basin area nor far from the Old Faithful Geyser. This area that measures about 2 square km sees numerous geysers that appear and disappear representing change in geologic activity of the Yellowstone Supervolcano underneath. Some erupt constantly every 2- 3 minutes, while some are dormant for years. Grand Geyser is one of the largest and powerful geysers among these. It constantly spews columns of hot water into a sky at a height of 60 meters. Tourists admire Grand Geyser from a small path that lies along geysers. It would be very foolish to leave the hiking trail and take a closer look of the formation. Boiling water and immense force can easily harm and even kill anyone who will approach geysers too closely.

 

Yellowstone Caldera

Yellowstone Caldera

Yellowstone Caldera is the volcanic caldera of Yellowstone Supervolcano that is hidden below subsequent geologic formations. Caldera is formed by the collapse of large land area following a volcanic eruption. Its name is derived from Latin caldaria that can be translated as "cooking pot". Yellowstone Supervolcano is the largest known volcano on the planet that lies dormant for many millions of years. Its last eruption occurred seventy thousand years, but the constant geothermal activity continues to this day. It is visible through earthquakes, changes in topography and activity of geysers. Eruption of Yellowstone Supervolcano can potentially end life not only in the North American, but damage most of the planet.

Despite potential danger Yellowstone Caldera is one of the most visited places in the Yellowstone National Park. Local thermal lake is painted in a rainbow of colors. Hot springs decorate landscape with stone columns and stelae. This area is easily accessible by a network of hiking trails.

 

Fees and permits

All vehicles and individuals entering Yellowstone National Park must pay an entrance fee that is valid for seven days. The fee is $35 for non-commercial vehicles, $15 for hikers and cyclists, and $25 for motorcycles and snowmobiles. As an alternative to the seven-day fee, you can buy a Park Annual Pass, which costs $60 and is valid until the end of the month 1 year after the purchase date.

If you plan to visit both Yellowstone and Grand Teton National Parks, you can pay a single entrance fee for both at a discount compared to paying two separate fees for the two parks. The combined fee is $50 for non-commercial vehicles, $20 for hikers and cyclists, and $40 for motorcycles and snowmobiles.

There are several passes for groups traveling together in a private vehicle or individuals on foot or on bike. These passes provide free entry at national parks and national wildlife refuges, and also cover standard amenity fees at national forests and grasslands, and at lands managed by the Bureau of Land Management and Bureau of Reclamation. These passes are valid at all national parks including Yellowstone National Park:

The $80 Annual Pass (valid for twelve months from date of issue) to Yellowstone National Park can be purchased by anyone. Military personnel can obtain a free annual pass in person at a federal recreation site by showing a Common Access Card (CAC) or Military ID.
U.S. citizens or permanent residents age 62 or over can obtain a Senior Pass (valid for the life of the holder) in person at a federal recreation site for $80, or through the mail for $90; applicants must provide documentation of citizenship and age. This pass also provides a fifty percent discount on some park amenities. Seniors can also obtain a $20 annual pass.
U.S. citizens or permanent residents with permanent disabilities can obtain an Access Pass (valid for the life of the holder) in person at a federal recreation site at no charge, or through the mail for $10; applicants must provide documentation of citizenship and permanent disability. This pass also provides a fifty percent discount on some park amenities.
Individuals who have volunteered 250 or more hours with federal agencies that participate in the Interagency Pass Program can receive a free Volunteer Pass.
4th graders can receive an Annual 4th Grade Pass that allows free entry for the duration of the 4th grade school year (September-August) to the bearer and any accompanying passengers in a private non-commercial vehicle. Registration at the Every Kid in a Park website is required.
In 2018 the National Park Service will offer four days on which entry is free for all national parks: January 15 (Martin Luther King Jr. Day), April 21 (1st Day of NPS Week), September 22 (National Public Lands Day), and November 11 (Veterans Day weekend).

History

An Indian settlement for over 11,000 years has been proven. Around 1807 the trapper John Colter was probably the first white person to see the area of today's national park. Northern Shoshone were also to be found there in Colter's time. Other tribes such as the Blackfoot, Absarokee, and Bannock occasionally roamed the Yellowstone area for hunting and fishing. At Obsidian Cliff, they found plenty of obsidian rock, which they used to make cutting tools and weapons. Yellowstone obsidian arrowheads have also been found in the Mississippi River Valley.

John Colter returned to civilization in 1810. His descriptions of Yellowstone were hardly noticed. The area was inaccessible, so it was not quickly settled by whites; however, a few fur hunters and prospectors ventured there, such as Warren Ferris in 1834 and Jim Bridger in 1857. Their reports were also largely ignored, but not by geologist Ferdinand V. Hayden. In 1859 he presented an expedition led by Bridger and the US Inspector W.F. Raynolds together. The expedition foundered due to the onset of winter even before it could enter the Yellowstone area. Only after the American Civil War was another attempt made. With the success of the Folsom Expedition in 1869, Montana's Inspector General Henry Dana Washburn became interested in the Yellowstone area. A year later, together with the writer Nathaniel P. Langford and Lieutenant Gustavus C. Doane, he put together the Washburn-Langford-Doane Expedition. Among other things, this gave the geyser Old Faithful its name. Also present was Truman Everts, who almost lost his life under the most adventurous circumstances. Finally, the press was ready to report on the extraordinary area. The accounts were received with great interest across the country.

Ferdinand V. Hayden was encouraged by Washburn and in 1871 again started a two-year research trip to the area. The 34-strong group also included painter Thomas Moran and photographer William Henry Jackson. The pictorial and written testimonies of another expedition, the Barlow Heap Expedition, which set out at the same time, were destroyed in the Great Chicago Fire in October 1871 immediately after their return, so that Moran's pictures and Jackson's photos gained importance.

The Sheepeater Shoshonen lived in the area of today's park until 1871. They then joined other Shoshone groups on the Wind River Indian Reservation. In the meantime, the white settlers had advanced far to the west and had not only pushed out the Indians, but also many animals and plants. The Rocky Mountains were the last retreat. Environmentalists demanded a protected area for animals and plants. The reports and pictures of the participants of the expeditions to the Yellowstone region with its approximately 10,000 hot springs, including over 500 geysers, impressed the parliamentarians in Washington, D.C. so much so that in 1872 they passed a law protecting the Yellowstone area from prospectors, settlers and trappers. On March 1, 1872, President Ulysses S. Grant signed the law into law, establishing the world's first national park. The primary goal of the founding was not nature conservation, but "a public park or amusement park for the benefit and enjoyment of the people". The Northern Pacific Railway had lobbied heavily for the establishment of the park, hoping to be able to utilize their trains more efficiently.

For the next five years, Nathaniel P. Langford served as honorary superintendent of the park—the US provided no funds for the park. His successor was Philetus Walter Norris, after whom a town in the park was named. During his tenure, Congress awarded the superintendent a salary and minimal funds to run the park. Norris used the funds to better develop the park. He also hired Harry Yount (known as Rocky Mountain Harry) to help stop poaching and vandalism. Today, Harry Yount is considered the first park ranger.

In 1876, the Hunkpapa Lakota under Sitting Bull flocked to the park in search of prey scarce on the Great Plains farther east. A year later in the Nez-Percé War, Chief Joseph and his Nez Percé escaped through Yellowstone before the US Army could intercept them just short of the Canadian border. No Native American groups have lived in the Yellowstone area since the 1880s.

After the park opened, many travelers initially came to the park primarily for their hunting pleasure. In 1883, the Northern Pacific Railroad opened up Yellowstone National Park through a station at Livingston, just north of the park. For the inauguration of the new line, the railroad company invited 365 journalists and celebrities, including former US President and park founder Ulysses S. Grant, to a free ride to Yellowstone. The extra train left New York on August 29 and arrived in the National Park on September 6. Northern Pacific Railroad dubbed the new line The Wonderland Route and marketed the park in the style of Buffalo Bill's Wild West show.

Three other superintendents followed Norris, but they were just as unable to stop the destruction of the park's natural resources. The management of the park was therefore entrusted to the US Army in 1886 and the National Park Protection Act 1894 created the legal basis for its protection. During the military leadership, troops were stationed at Fort Yellowstone near what is now Mammoth Hot Springs.

From 1915 cars were allowed to enter the national park. In 1916, the newly formed National Park Service assumed responsibility. That year, 35,800 tourists, half of whom came by car, viewed the park, which among other things led to noise pollution. To this day, one of the National Park Services' responsibilities is to strike a balance between visitor satisfaction and conservation.

In the summer of 1936, future US President Gerald Ford was working as a park ranger in Yellowstone National Park. He was responsible for feeding the bears. Until the beginning of the Second World War, the number of visitors rose steadily to 581,000 visitors per year (1941). It then dropped to 85,000 (1944) and increased sharply after the war, from 815,000 in 1946 to over a million two years later. In 1965 it passed the two million mark for the first time.

 

Geography and geology

With 96 percent of the area, Yellowstone National Park is almost entirely in the US state of Wyoming, 3 percent is in Montana and 1 percent in Idaho. With an area of 8987 km², it is one of the largest national parks in the USA. The area of the national park corresponds approximately to the size of Corsica. The north-south extent is 102 kilometers, the east-west extent 87 kilometers. Yellowstone National Park is part of the Rocky Mountains and averages about 2440 meters above sea level. Eagle Peak, the highest point in the park, is 3462 meters, and the lowest point, at the northern entrance, is 1620 meters.

Large parts of the national park are located in the caldera of the Yellowstone volcano, which was formed around 640,000 years ago, above the magma chamber, which is more than 8 kilometers deep. The magma chamber is around 80 kilometers long, 40 kilometers wide and 10 kilometers thick. This means that the Yellowstone volcano belongs to the group of supervolcanoes. It is the largest supervolcano on the American continent.

The park is famous for its volcanic landscape with geysers, fumaroles, mud pots and hot springs. 62 percent of all hot springs in the world are in the Yellowstone area, these are about 10,000, including over 500 geysers, so Yellowstone National Park has the highest density of geysers.[7] Of the more than 300 geysers in the national park, the Old Faithful geyser in the upper geyser basin is particularly popular with tourists because it spits out its water with unusual regularity at intervals of about 60 to 90 minutes (as of 2018). The park is also home to the largest active warm water geyser in the world, Steamboat Geyser. It is located in Norris Geyser Basin. The largest hot spring in Yellowstone National Park and the third largest in the world, Grand Prismatic Spring is located in the middle geyser basin.

The cause of the volcanogenic activity is the volcano's magma chamber, which heats the water flowing down from mountains and seeping into the porous lava rock. The seeped water resurfaces in hot springs, geysers or bubbling mud pools.

Smaller volcanic eruptions between 630,000 and 70,000 years ago almost completely filled the caldera with lava rock. Today the park is on a high plateau at around 2,400 meters and is almost entirely bordered by mountain ranges from the middle Rocky Mountains, the peaks of which are between 3,000 and 4,300 meters high. To the northwest is the Gallatin Range, to the north is the Beartooth Mountains, to the east is the Absaroka Range, to the south is the Teton Range, and to the west is the Madison Range. The most famous mountain on the high plateau itself is Mount Washburn with a height of 3122 meters. Part of the Yellowstone Plateau is Yellowstone Lake, the largest mountain lake in North America. Partially outside of the park is the Island Park Caldera, a plateau ringed by low hills.

The main North American watershed runs diagonally through the southwest portion of the park. This is a ridge line separating the flow of water into the Pacific and the Atlantic. Three major rivers originate in the park's mountains. The Yellowstone River gave the national park its name. It leaves the national park in the north and finally flows into the Atlantic via the Missouri River, the Mississippi River and the Gulf of Mexico. The waters of the Madison River drain to the west and also end up in the Atlantic via the Missouri-Mississippi river system. The Snake River flows south out of the park and empties into the Pacific Ocean, although its headwaters are very close to the headwaters of the Yellowstone River. In total, the park has 290 waterfalls with a drop of at least 4.5 meters, including the neighboring Lower Falls, at 94 meters the highest falls in the park, and Upper Falls in the Grand Canyon of the Yellowstone, as well as the Tower Fall at the mouth of the Tower Creek into the Yellowstone River.

The national park can be divided into five zones (countries). Located in the northwest of the park, Mammoth Country is dominated by the thermal springs and limestone terraces at Mammoth Hot Springs. Herds of wapiti can often be observed here. Roosevelt Country in the Northeast is least visited by tourists. This hilly landscape is home to many wildlife such as deer and bison. The west of the park, the Canyon Country, is determined by the almost 400 meter deep Grand Canyon of the Yellowstone with its waterfalls and by the Hayden Valley with its large herds of bison. The Lake Country in the southeast with various lakes such as Yellowstone Lake or Heart Lake is home to animals such as fish, birds of prey, moose and bears. The southwest is the area with most of the park's geysers and hot springs, including Old Faithful and Steamboat Geyser. It is appropriately named Geyser Country.

In the last 300,000 years or so, the surface of the park area was shaped by the glaciers of the Ice Age. Three glaciations formed a large plateau glacier in the center of what is now the park and several glaciers originating from the Absaroka Range to the east. Together they almost completely covered the park area and extended well beyond its borders to the north and south. Signs of glaciation can still be seen today in the form of the park's lake basins, particularly Yellowstone Lake, the trough valleys in the mountain portions of the park, and the gravel, sand, and lake clay-filled valleys of Slough Creek in the northeast part of the park and the headwaters of the Yellowstone River , where the meandering rivers form their beds in a wide valley. Boulders to the north-east of the park, near the road to Cooke City, also date from the last Ice Age. The forest returned to the national park area around 10,500-9500 years ago.

 

Climate

The climate in Yellowstone National Park is primarily characterized by its location in the Rocky Mountains. In Mammoth Hot Springs, the average daily low in January is -13 °C and the daily high in July is 27 °C. Sudden weather changes are to be expected in the park throughout the year.

In summer, daytime temperatures of 25°C are common in the lower-lying areas, occasionally reaching 30°C. Thunderstorms are common in the afternoon. Nights are cool even in summer; temperatures can drop below freezing in the mountains. In winter, they typically range between −20 °C and −5 °C during the day. The highest temperature at 37 °C was recorded in the Lamar Valley in 1936, the lowest at -54 °C in 1933 in Madison.

On average, 183 cm of snow falls annually, significantly more in higher regions than in the valleys. Occasional snowfall is also normal in spring and autumn. Average rainfall ranges from 10 inches (26 cm) per year at Mammoth Hot Springs in the north to 80 inches (205 cm) in the southwest of the park.

Tornadoes in Yellowstone National Park are rare. On July 21, 1987, the most powerful tornado recorded in the park was the Teton-Yellowstone Tornado. The wind speeds of 333 to 418 km/h reached F4 on the Fujita scale. The tornado left a path one to two miles (1.6 to 3.2 kilometers) wide and 38 kilometers long in the Teton Wilderness and Yellowstone National Park.

In 2005, researchers found several surviving juniper trees around 1,500 years old near Mammoth Hot Springs and a nearly 2,000-year-old pine (Pinus flexilis) in the Absaroka Mountains. These trees will now be examined in detail. Scientists hope to gain new insights into the climatic conditions of the last two millennia.

In June 2022, a combination of heavy rainfall and rapid snowmelt led to flooding and landslides. The national park had to be closed. Gardiner, Montana was cut off from the outside world. The Yellowstone River reached a record high of 13.88 feet (4.23 meters). The clean-up work, especially in the northern part, will take months. The southern loop was reopened on June 22nd; a large part of the northern circuit (northern loop) was also passable again from July 2, 2022. The northern and north-eastern park entrances remained closed.

 

Flora and vegetation

Around 80 percent of the park area is covered by coniferous forest, the rest is divided into meadow (15 percent) and water (5 percent). The coniferous forest prevails especially inside the caldera. Around three-quarters of it consists of long-spined coastal pines (subsp. latifolia), and various types of spruce and aspen are also widespread in the park, especially the Engelmann spruce in areas with volcanic soil. Whitebark pines (Pinus albicaulis) make up a significant proportion of forests at higher elevations and Douglas firs at lower elevations. Non-forested areas are in many places - especially in the northern part of the park - a sagebrush steppe. It is dominated by grass species such as the Idaho fescue (Festuca idahoensis). Grasses, sedges, rushes and tall forbs grow in wetter areas. In spring, meadow herbs (Claytonia), large-flowered dog's teeth (Erythronium grandiflorum) and Dicentra uniflora (Longhorn Steer's-head) bloom in the meadows. In summer they are replaced by Balsamorhiza sagittata (Arrowleaf Balsamroot), phlox, penstemon and lupins. Goldenrods (Solidago) and gentians (Gentiana) each herald the fall.

A total of 186 known lichen species and around 2000 plant species can be found in the park, including 12 tree species and over 60 wildflower species, 12 of which are orchid species. Some of these plants are only found in the national park. The hot springs affect the park's vegetation. Direct contact with the siliceous, warm water is destructive for most plants. Others, in turn, change their growth rhythm as a result.

 

Fauna

The park is a retreat for animal species that have become rare, such as bison and pronghorn. Mule deer, cougar and lynx are native to the lower areas of the park, and bighorn sheep and mountain goats are native to the higher elevations. Wapiti are mainly found in the region around Mammoth Hot Springs. Other mammals in the park include moose, black bears, at least eight species of bats (with the lesser brown bat being by far the most common) and in the hinterland grizzly bears, wolves and coyotes, but also chipmunks, gray squirrels, silver badgers, beavers, marmots, tree porcupines and muskrats and around 40 other species.

Attacks by bears on humans are rather rare, because bears avoid the proximity of humans. Dangerous encounters between bears and humans can only occur if an animal is harassed or has young with it. Most wildlife accidents happen to bison. Many visitors fail to recognize that these are also wild animals and underestimate the potential of these animals. Bison are unpredictable and can accelerate very quickly to over 50 km/h and maintain this speed for long periods of time.

Of the park's 18 species of fish, Yellowstone cutthroat trout (Oncorhynchus clarki bouvieri) are particularly popular with anglers. However, Yellowstone cutthroat trout are being pushed out by introduced, non-native lake trout. Over 70,000 Yellowstone cutthroat trout were counted in Clear Creek east of Yellowstone Lake in the 1970s, down from 471 in the spring of 2006.

There were 318 bird species (as of April 2004) officially registered. Common bird species here include the cinnamon duck, broad-tailed sprite (a species of hummingbird), red-necked saplicker (a species of woodpecker), tit and blue jay, magpie, rhinoceros pelican, cormorant, spatel duck, gray owl and sandhill crane. With a bit of luck you can see bald eagles, goshawks, rock grouse and pine sap lickers. Among the rarer birds, mention should be made of loon, harlequin duck, osprey, peregrine falcon and trumpeter swans. In the forest areas affected by the fire, there are good opportunities to observe Spruce Woodpeckers and Black-backed Woodpeckers. In 1998, two whooping cranes were also sighted in the park. However, this is an absolute exception.

The cool and dry climate limits the reptiles in the park to six and the amphibians to four species.

Reptiles: Prairie Rattlesnake, Bull Snake, California Garter Snake, Migratory Garter Snake, Rubber Boa and Sagebrush Lizard Sceloporus graciosus.
Amphibians: Western toad, choir frog, tiger salamander and the frog species Rana pretiosa (Oregon spotted frog).
The size of amphibian populations fell to less than half between 1992 and 2008 as ponds dried up due to global warming.

 

Thermophilic archaea, bacteria and algae

A wide variety of thermophilic archaea, bacteria and microalgae live in the hot springs of Yellowstone National Park. Only a few of these microbial communities have been scientifically studied, such as those from the Culex Basin or the Obsidian Pool. Among the most important researched thermophilic bacteria discovered in Yellowstone National Park are Thermus aquaticus and various cyanobacteria. In 2009, the park's eukaryotic algae of the genus Cyanidioschyzon were found to tolerate high concentrations of arsenic and bind the arsenic into complex organic compounds. The arsenic is much less available in this form for other organisms and no longer develops its toxic effect. These algae exist in waters of Yellowstone National Park fed by geysers and other volcanic hot springs. Work is underway to use it for depletion in drinking water.

The National Park Service entered into an agreement with US biotech company Diversa in August 1997 "in which the company received intellectual property rights to the heat-stable microorganisms that live in the park's geysers and hot springs. This agreement came to light in March 1998, prompting several NGOs to protest and take legal action against this case of biopiracy. In March 1999, this bioprospecting contract was finally annulled by a US court.”

The bacteria, isolated from sources in Yellowstone National Park, hold huge financial potential for pharmaceutical companies. The Swiss company Roche, for example, sells an enzyme from Thermus aquaticus, the Taq polymerase, for the replication of genetic material (DNA) and thus achieves billions in revenue. According to a 2000 court ruling, the National Park Service is authorized to receive a future financial contribution from research conducted in Yellowstone National Park.

 

Natural reserve

Conservationists such as George Catlin and Henry David Thoreau had already called for the protection of nature and animals in the Yellowstone region before the founding of Yellowstone National Park as the first national park ever. When the park was founded, however, corresponding protective measures were not enshrined in law; they only flowed in over time. Since January 15, 1883, more than ten years after it was founded, most animals in the park have been banned from hunting. However, poachers could not be legally prosecuted and so people who wanted to hunt used the opportunity to shoot wild animals again and again. With the National Park Protection Act (also known as the Lacey Act) of May 7, 1894, the US Parliament created the legal basis for actual protection of wildlife, birds and natural resources. The law prohibits the killing of all animals in the park, except for fishing without a net. Trees, minerals and rarities of nature must not be damaged.

At this point the bison population in the park was estimated at around 200 animals and the Yellowstone herds consisted of the last wild bison. In the years 1896 to 1902, estimates by the park officials varied between 22 and 50 bison. In 1902 they bought 15 cows and 3 bulls from external bison farms and moved them to a specially constructed pen south of Fort Yellowstone. By 1920, Yellowstone's bison population had recovered to around 500 animals. Today the herds consist of stabilized populations of between 3,500 and 4,500 animals; in 2005, those responsible for the park reported a high of around 5,000 animals. Every winter the bison migrate north in search of food, and many leave the park. Local farmers fear the bison could infect their cattle with brucellosis. Whether this is possible has not been proven. Bison outside the park are either chased back or slaughtered. Around 1,500 Yellowstone bison are killed outside the park each year.

The grizzly bear has been protected in Yellowstone National Park since 1886. From 1975 to 2007 it was on the U.S. List of Threatened and Endangered Species. Fish and Wildlife Services and was therefore also protected outside the park. Today over 500 animals live in the park or in the adjacent area; In 1975, there were 136 to 312. In 2009, a Montana District Court dismissed the U.S. Fish & Wildlife Service to put the grizzly back on their list of threatened and endangered species.

In the 1970s, black bears became accustomed to the tourists, eating litter and human food. In the meantime, informative leaflets and a strict feeding ban have successfully kept the bears away from the camping and picnic areas and thus protect them from dependence. Today, feeding all animals in the park is prohibited.

The Yellowstone area wolves were hunted for years and became extinct in the 1930s. As a direct result, the natural balance of wildlife was upset. Therefore, in 1995, 14 Canadian wolves were successfully resettled and placed under protection. Meanwhile, the Yellowstone wolves have interbred with immigrant wolves from Canada and their population has increased to nearly 100 animals within the park (late 2009) and 1,645 animals (late 2008) in the Idaho/Montana/Wyoming area. As of March 28, 2008, Yellowstone wolves were scheduled to be removed from the federal endangered species list. Protection of the wolf population would have passed from the US Fish & Wildlife Service to the three affected US states of Wyoming, Montana and Idaho. The project was stopped by a federal court in July 2008 after complaints by a coalition of nature conservation organizations because the measures in Wyoming failed to meet the level of protection prescribed by the federal government and the preservation of the population was not guaranteed as a result. In August 2010, the lawsuit was upheld on the grounds that the wolf population in the Yellowstone area should be viewed as a whole. In May 2011, the species finally transitioned into state jurisdiction in Idaho and Montana, and after Wyoming enacted adequate protection legislation, the wolf was released from federal protection there as well in October 2012.

Since the reintroduction of wolves, the elk population in the northern Yellowstone area has declined from 17,000-19,000 to around 4,600 animals in December 2010. A main reason, apart from the greater drought in recent years, is that elk move to higher areas with less food in winter because of the wolves.

In 1988 there was the last major forest fire (see fires in Yellowstone National Park 1988), which covered almost 4000 km² of the park: 2300 km² of forest burned completely, on 1450 km² only the undergrowth. In addition, the grass and occasionally bushes burned on 250 km². In the past, every kind of forest fire was fought immediately, but since 1988 it has been recognized that forest fires in the park are something completely normal. Forest fires are no longer fought, only observed to prevent uncontrolled spread. Some of the forest fires are started intentionally so that catastrophic fires like the one in 1988 do not occur. The effects of this fire were still clearly visible in many places more than 20 years later.

 

Tourism

The park can be reached via five entrances. North from Livingston and Gardiner (Montana), northeast from Red Lodge and Cooke City via Beartooth Pass (Wyoming), east from Cody, south from Jackson and from Grand Teton National Park (Wyoming) via John D Rockefeller, Jr. Memorial Parkway and to the west of Idaho Falls (Idaho) and West Yellowstone (Montana). It combines a variety of attractions: geysers, hot springs, a deep canyon, a river with multiple falls, forests, lakes, mountains, wilderness and wildlife. The tourist opportunities are correspondingly varied. They range from hiking and mountaineering to kayaking and fishing to wildlife viewing and horseback riding. Hikers can choose from around 2,000 kilometers of marked hiking trails spread across the entire park.

Hotel and cabin accommodation is available in the towns of Mammoth Hot Springs in Mammoth Country; Tower Roosevelt in Roosevelt Country; Canyon Village in Canyon Country; Lake Village and Grant Village in Lake Country; and at Old Faithful in Geyser Country. The park also has 11 campgrounds and an RV-only site at Fishing Bridge because of the bear hazard. The villages are connected by streets in the shape of a large figure of eight. Depending on the season and snow conditions, some roads and towns in the park are closed.

The peak season in Yellowstone National Park lasts from early May to late October. From mid-June to the end of August all facilities such as accommodation, gas stations and restaurants are accessible, during the rest of the time only parts of them. During the winter, all roads in the park are open to snowmobiles and snow coaches (chain-driven buses) only, except for the road from the North Entrance to the Northeast Entrance. The daily number of motorized snow vehicles in the park is limited. Driving without a recognized guide is not permitted.

In the 1980s, almost ten times more tourists used snowmobiles in Yellowstone National Park than in 1968. By 1995, the number of snowmobiles reached 75,000 a year. Environmentalists are increasingly drawing attention to the negative consequences such as stress in animals due to the noise and environmental pollution. US President Clinton had snowmobiles banned in Yellowstone National Park in January 2001, shortly before George W. Bush was handed over office. His successor lifted the ban, but issued stricter technical specifications and a limit on the maximum number of snowmobiles permitted per year. Since then, environmentalists and the snowmobile lobby have been in a legal tug-of-war over the height, which is constantly being adjusted accordingly. At the same time, the National Park Service is conducting extensive studies into the impact of snowmobiles in the park.

 

At least 2.8 million tourists have visited the park every year since 1990. The largest number of visitors so far was counted in 2016 with over 4.25 million people. In the winter season, the number of visitors is around 140,000.

About 4500 workers are employed in the park during the peak season. Hotels, restaurants and shops in the park are operated by Xanterra Parks & Resorts. The concessionaire received the 2007 Travel Industry Association and National Geographic Traveler Magazine Geotourism Award for Sustaining the Environment of a Place for its sustainable tourism efforts in Yellowstone National Park.
