Glacier National Park is a national park of the United States located in northwestern Montana, on the Canada–United States border. The park encompasses more than 1 million acres (4,100 km2) and includes parts of two mountain ranges (sub-ranges of the Rocky Mountains), more than 130 named lakes, more than 1,000 different species of plants, and hundreds of species of animals. This vast pristine ecosystem is the centerpiece of what has been referred to as the "Crown of the Continent Ecosystem", a region of protected land encompassing 16,000 sq mi (41,000 km2).[4]

The region that became Glacier National Park was first inhabited by Native Americans. Upon the arrival of European explorers, it was dominated by the Blackfeet in the east and the Flathead in the western regions. Under pressure, the Blackfeet ceded the mountainous parts of their treaty lands in 1895 to the federal government which became part of the park. Soon after the establishment of the park on May 11, 1910, a number of hotels and chalets were constructed by the Great Northern Railway. These historic hotels and chalets are listed as National Historic Landmarks and a total of 350 locations are on the National Register of Historic Places. By 1932 work was completed on the Going-to-the-Sun Road, later designated a National Historic Civil Engineering Landmark, which provided motorists easier access to the heart of the park.

Glacier National Park's mountains began forming 170 million years ago when ancient rocks were forced eastward up and over much younger rock strata. Known as the Lewis Overthrust, these sedimentary rocks are considered to have some of the finest examples of early life fossils on Earth. The current shapes of the Lewis and Livingston mountain ranges and positioning and size of the lakes show the telltale evidence of massive glacial action, which carved U-shaped valleys and left behind moraines that impounded water, creating lakes. Of the estimated 150 glaciers over 25 acres (10 ha) in size which existed in the park in the mid-19th century during the late Little Ice Age, only 25 active glaciers remained by 2010.[5] Scientists studying the glaciers in the park have estimated that all the active glaciers may disappear by 2030 if current climate patterns persist.[6]

Glacier National Park still maintains almost all of its modern, original native plant and animal species (since discovery by Europeans). Large mammals such as American black bear, grizzly bear, bighorn sheep, elk, moose, mountain lion and mountain goats, as well as gray wolf, wolverine and Canadian lynx inhabit the park. Hundreds of species of birds, more than a dozen fish species, and quite a few reptiles and amphibian species have been documented. Species of butterflies, pollinating insects and other invertebrates range in the thousands.

The park has numerous ecosystems, ranging from prairie to tundra. The easternmost forests of western redcedar and hemlock grow in the southwest portion of the park. Forest fires are annually common in the park. There has been a fire every year of the park's existence except for in 1964. In total, 64 fires occurred in 1936 alone, the most on-record.[7][8] In 2003, six fires burned approximately 136,000 acres (550 km2), more than 13% of the park.[9]

Glacier National Park borders Waterton Lakes National Park in Canada—the two parks are known as the Waterton-Glacier International Peace Park and were designated as the world's first International Peace Park in 1932. Both parks were designated by the United Nations as Biosphere Reserves in 1976, and in 1995 as World Heritage Sites.[10] In April 2017, the joint park received a provisional Gold Tier designation as Waterton-Glacier International Dark Sky Park through the International Dark Sky Association,[11] the first transboundary dark sky park.

## History

[edit]

Blackfeet camp at upper St. Mary Lake, c. 1916[12]

The earliest occupants of the Glacier area with lineage to current tribes were the Flathead (Salish) and Kootenai,[13] Shoshone, and Cheyenne. The Blackfeet lived on the eastern slopes of what later became the park, as well as the Great Plains immediately to the east.[14] The park region provided the Blackfeet shelter from the harsh winter winds of the plains, allowing them to supplement their traditional bison hunts with other game meat. The Blackfeet Indian Reservation borders the park in the east, while the Flathead Indian Reservation is located west and south of the park. When the Blackfeet Reservation was first established in 1855 by the Lame Bull Treaty, it included the eastern area of the current park up to the Continental Divide. To the Blackfeet, the mountains of this area, especially Chief Mountain and the region in the southeast at Two Medicine, were considered the "Backbone of the World" and were frequented during vision quests.[15] In 1895 Chief White Calf of the Blackfeet authorized the sale of the mountain area, some 800,000 acres (3,200 km2), to the U.S. government for $1.5 million, with the understanding that they would maintain usage rights to the land for hunting as long as the ceded strip will be "public land of the United States".[16] This established the current boundary between the park and the reservation.[17][18]

> Far away in northwestern Montana, hidden from view by clustering mountain peaks, lies an unmapped corner—the Crown of the Continent.

—George Bird Grinnell (1901)[19]

While exploring the Marias River in 1806, the Lewis and Clark Expedition came within 50 mi (80 km) of the area that is now the park.[20] A series of explorations after 1850 helped to shape the understanding of the area that later became the park. In 1885 George Bird Grinnell hired the noted explorer (and later well-regarded author) James Willard Schultz to guide him on a hunting expedition into what would later become the park.[21] After several more trips to the region, Grinnell became so inspired by the scenery that he spent the next two decades working to establish a national park. In 1901 Grinnell wrote a description of the region in which he referred to it as the "Crown of the Continent". His efforts to protect the land made him the premier contributor to this cause.[22] A few years after Grinnell first visited, Henry L. Stimson and two companions, including a Blackfoot, climbed the steep east face of Chief Mountain in 1892.[23]

In 1891, the Great Northern Railway crossed the Continental Divide at Marias Pass 5,213 ft (1,589 m), which is along the southern boundary of the park. In an effort to attract passengers, the Great Northern soon advertised the splendors of the region to the public. The company lobbied the United States Congress. In 1897 the park was designated as a forest preserve.[24] Under the forest designation, mining was still allowed but was not commercially successful. Meanwhile, proponents of protecting the region kept up their efforts. In 1910, under the influence of the Boone and Crockett Club,[25] and spearheaded by George Bird Grinnell and Louis W. Hill, president of the Great Northern, a bill was introduced into the U.S. Congress which designated the region a national park. This bill was signed into law by President William Howard Taft in 1910.[26] In 1910 Grinnell wrote, "This Park, the country owes to the Boone and Crockett Club, whose members discovered the region, suggested it being set aside, caused the bill to be introduced into congress and awakened interest in it all over the country".[27]

Many Glacier Hotel on Swiftcurrent Lake

From May until August 1910, the forest reserve supervisor, Fremont Nathan Haines, managed the park's resources as the first acting superintendent. In August 1910, William Logan was appointed the park's first superintendent. While the forest reserve designation confirmed the traditional usage rights of the Blackfeet, the enabling legislation of the national park does not mention the guarantees to the Native Americans. The United States government's position was that with the special designation as a National Park the mountains ceded their multi-purpose public land status and the former rights ceased to exist as the Court of Claims confirmed it in 1935. Some Blackfeet held that their traditional usage rights still exist de jure. In the 1890s, armed standoffs were avoided narrowly several times.[28]

The Great Northern Railway, under the supervision of president Louis W. Hill, built a number of hotels and chalets throughout the park in the 1910s to promote tourism. These buildings, constructed and operated by a Great Northern subsidiary called the Glacier Park Company, were modeled on Swiss architecture as part of Hill's plan to portray Glacier as "America's Switzerland". Hill was especially interested in sponsoring artists to come to the park, building tourist lodges that displayed their work. His hotels in the park never made a profit but they attracted thousands of visitors who came via the Great Northern.[29] Vacationers commonly took pack trips on horseback between the lodges or utilized the seasonal stagecoach routes to gain access to the Many Glacier areas in the northeast.[30]

Saint Mary Lake and Wild Goose Island

The chalets, built between 1910 and 1915, included Belton, St. Mary, Going-to-the-Sun, Many Glacier, Two Medicine, Sperry, Granite Park, Cut Bank, and Gunsight Lake. The railway also built Glacier Park Lodge, adjacent to the park on its east side, and the Many Glacier Hotel on the east shore of Swiftcurrent Lake. Louis Hill personally selected the sites for all of these buildings, choosing each for their dramatic scenic backdrops and views. Another developer, John Lewis, built the Lewis Glacier Hotel on Lake McDonald in 1913–1914. The Great Northern Railway bought the hotel in 1930 and it was later renamed Lake McDonald Lodge.[31] The Great Northern Railway also established four tent camps at Red Eagle Lake, Cosley Lake, Fifty Mountain and Goat Haunt. The chalets and tent camps were located roughly 10–18 miles apart, and were connected by a network of trails that allowed visitors to tour Glacier's backcountry on foot or horseback. These trails were also constructed by the railroad. "Because of a lack of federal funds Great Northern assumed financial responsibility for all trail construction during this period, but was eventually reimbursed as funding became available."[32] Today, only Sperry, Granite Park, and Belton Chalets are still in operation, while a building formerly belonging to Two Medicine Chalet is now Two Medicine Store.[33] The surviving chalet and hotel buildings within the park are now designated as National Historic Landmarks.[34] In total, 350 buildings and structures within the park are listed on the National Register of Historic Places, including ranger stations, backcountry patrol cabins, fire lookouts, and concession facilities.[35] In 2017, Sperry Chalet closed early for the season due to the Sprague Fire which subsequently burned the entire interior portions of the structure, leaving only the stone exterior standing. Due to damage, the chalet was closed indefinitely and while the exterior stonework was stabilized in the fall of 2017.[36] The rebuilding process was completed during the summers of 2018 and 2019,[37] and a reopening ceremony was held in February 2020.[38]

Road construction along the Going-to-the-Sun Road with Going-to-the-Sun Mountain in the background, 1932

After the park was well established and visitors began to rely more on automobiles, work was begun on the 53-mile (85 km) long Going-to-the-Sun Road, completed in 1932. Also known simply as the Sun Road, the road bisects the park and is the only route that ventures deep into the park, going over the Continental Divide at Logan Pass, 6,646 ft (2,026 m) at the midway point. The Sun Road is also listed on the National Register of Historic Places and in 1985 was designated a National Historic Civil Engineering Landmark.[39] Another route, along the southern boundary between the park and National Forests, is US Route 2, which crosses the Continental Divide at Marias Pass and connects the towns of West Glacier and East Glacier.[40]

The Civilian Conservation Corps (CCC), a New Deal relief agency for young men, played a major role between 1933 and 1942 in developing both Glacier National Park and Yellowstone National Park. CCC projects included reforestation, campground development, trail construction, fire hazard reduction, and fire-fighting work.[41] The increase in motor vehicle traffic through the park during the 1930s resulted in the construction of new concession facilities at Swiftcurrent and Rising Sun, both designed for automobile-based tourism. These early auto camps are now also listed on the National Register.[33]

## Park management

Glacier National Park is managed by the National Park Service, with the park's headquarters in West Glacier, Montana. Visitation to Glacier National Park averaged about 3.5 million visitors in 2019, which surpassed its 2017 peak of 3.31 million.[42][43] Glacier has had at least 2 million annual visitors consistently since 2012, but has broken annual attendance records from 2014 to 2018.[44]

In anticipation of the 100th anniversary of the park in 2010, major reconstruction of the Going-to-the-Sun Road was completed. The Federal Highway Administration managed the reconstruction project in cooperation with the National Park Service.[45] Some rehabilitation of major structures such as visitor centers and historic hotels, as well as improvements in wastewater treatment facilities and campgrounds, were expected to be completed by the anniversary date.[46] The National Park Service engaged in fishery studies for Lake McDonald to assess status and develop protection programs to enhance native fish populations.[47] The restoration of park trails, education and youth programs, park improvements and many community programs were also planned.[48]

The National Park Service mandate is to "... preserve and protect natural and cultural resources". The Organic Act of August 25, 1916 established the National Park Service as a federal agency. One major section of the Act has often been summarized as the "Mission", "... to promote and regulate the use of the ... national parks ... which purpose is to conserve the scenery and the natural and historic objects and the wildlife therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."[49] In keeping with this mandate, hunting is illegal in the park, as are mining, logging, and the removal of natural or cultural resources. Additionally, oil and gas exploration and extraction are not permitted. These restrictions caused a lot of conflict with the adjoining Blackfeet Indian Reservation. When they sold the land to the United States government, it was with the stipulation of being able to maintain their usage rights of the area, many of which (such as hunting) had come into conflict with these regulations.[16]

In 1974, a wilderness study was submitted to Congress which identified 95% of the area of the park as qualifying for wilderness designation. Unlike a few other parks, Glacier National Park has yet to be protected as wilderness, but National Park Service policy requires that identified areas listed in the report be managed as wilderness until Congress renders a full decision.[35] Ninety-three percent of Glacier National Park is managed as wilderness, even though it has not been officially designated.[50][failed verification]

## Geography and geology

Winter on the Flathead River Geological cross section of Glacier National Park (U.S.)

The park is bordered on the north by Waterton Lakes National Park in Alberta, and the Flathead Provincial Forest and Akamina-Kishinena Provincial Park in British Columbia.[51] To the west, the north fork of the Flathead River forms the western boundary, while its middle fork is part of the southern boundary. The Blackfeet Indian Reservation provides most of the eastern boundary. The Lewis and Clark and the Flathead National Forests form the southern and western boundary.[52] The remote Bob Marshall Wilderness Complex is located in the two forests immediately to the south.[53]

The park contains over 700 lakes, but only 131 have been named as of 2016.[54] Lake McDonald on the western side of the park is the longest at 10 mi (16 km) and the deepest at 464 ft (141 m). Numerous smaller lakes, known as tarns, are located in cirques formed by glacial erosion. Some of these lakes, like Avalanche Lake and Cracker Lake, are colored an opaque turquoise by suspended glacial silt, which also causes a number of streams to run milky white. Glacier National Park lakes remain cold year-round, with temperatures rarely above 50 °F (10 °C) at their surface.[54] Cold water lakes such as these support little plankton growth, ensuring that the lake waters are remarkably clear. However, the lack of plankton lowers the rate of pollution filtration, so pollutants tend to linger longer. Consequently, the lakes are considered environmental bellwethers as they can be quickly affected by even minor increases in pollutants.[55]

Two hundred waterfalls are scattered throughout the park. However, during drier times of the year, many of these are reduced to a trickle. The largest falls include those in the Two Medicine region, McDonald Falls in the McDonald Valley, and Swiftcurrent Falls in the Many Glacier area, which is easily observable and close to the Many Glacier Hotel. One of the tallest waterfalls is Bird Woman Falls, which drops 492 ft (150 m) from a hanging valley beneath the north slope of Mount Oberlin.[56]

### Geology

[edit]

Two Medicine Lake and Sinopah Mountain

Stromatolites, Belt Supergroup, dated to the Mesoproterozoic Era, ~1.44 billion years ago; polished slab at the Museum of the Rockies

The rocks found in the park are primarily sedimentary rocks of the Belt Supergroup. They were deposited in shallow seas over 1.6 billion to 800 million years ago. During the formation of the Rocky Mountains 170 million years ago, one region of rocks now known as the Lewis Overthrust was forced eastward 50 mi (80 km). This overthrust was several miles (kilometers) thick and hundreds of miles (kilometers) long.[57] This resulted in older rocks being displaced over newer ones, so the overlying Proterozoic rocks are between 1.4 and 1.5 billion years older than Cretaceous age rocks they now rest on.[57][58]

One of the most dramatic evidences of this overthrust is visible in the form of Chief Mountain, an isolated peak on the edge of the eastern boundary of the park rising 2,500 ft (800 m) above the Great Plains.[58][59] There are six mountains in the park over 10,000 ft (3,000 m) in elevation, with Mount Cleveland at 10,466 ft (3,190 m) being the tallest.[60] Appropriately named Triple Divide Peak sends waters towards the Pacific Ocean, Hudson Bay, and Gulf of Mexico watersheds. This peak can effectively be considered to be the apex of the North American continent, although the mountain is only 8,020 ft (2,444 m) above sea level.[61]

The rocks in Glacier National Park are the best preserved Proterozoic sedimentary rocks in the world, with some of the world's most fruitful sources for records of early life. Sedimentary rocks of similar age located in other regions have been greatly altered by mountain building and other metamorphic changes; consequently, fossils are less common and more difficult to observe.[62] The rocks in the park preserve such features as millimeter-scale lamination, ripple marks, mud cracks, salt-crystal casts, raindrop impressions, oolites, and other sedimentary bedding characteristics. Six fossilized species of stromatolites, early organisms consisting of primarily blue-green algae, have been documented and dated at about 1 billion years.[59] The discovery of Horodyskia within the Appekunny Formation, a well-preserved rock stratum in the park, pushed back the established date for the origination of eukaryotic life a full billion years.[58]

### Glaciers

[edit]

Main article: Glaciers in Glacier National Park (U.S.)

Glacial retreat since the end of the Little Ice Age in 1850

Glacier National Park is dominated by mountains which were carved into their present shapes by the huge glaciers of the last ice age. These glaciers have largely disappeared over the last 12,000 years.[63] Evidence of widespread glacial action is found throughout the park in the form of U-shaped valleys, cirques, arêtes, and large outflow lakes radiating like fingers from the base of the highest peaks.[6] Since the end of the ice ages, various warming and cooling trends have occurred. The last recent cooling trend was during the Little Ice Age, which took place approximately between 1550 and 1850.[64] During the Little Ice Age, the glaciers in the park expanded and advanced, although to nowhere near as great an extent as they had during the Ice Age.[63]

During the middle of the 20th century, examining the maps and photographs from the previous century provided clear evidence that the 150 glaciers known to have existed in the park a hundred years earlier had greatly retreated and disappeared altogether in many cases.[65] Repeat photography of the glaciers, such as the pictures taken of Grinnell Glacier between 1938 and 2015 as shown, help to provide visual confirmation of the extent of glacier retreat.[66]

In the 1980s, the U.S. Geological Survey began a more systematic study of the remaining glaciers, which has continued to the present day. By 2010, 37 glaciers remained, but only 25 of them were at least 25 acres (0.10 km2) in area and therefore still considered active.[5][65] Based on the warming trend of the early 2000s, scientists had estimated that the park's remaining glaciers would melt by 2020;[67] however, a later estimate stated that the glaciers may be gone by 2030.[6] This glacier retreat follows a worldwide pattern that has accelerated even more since 1980. Without a major climatic change in which cooler and moister weather returns and persists, the mass balance, which is the accumulation rate versus the ablation (melting) rate of glaciers, will continue to be negative and the glaciers have been projected to disappear, leaving behind only barren rock eventually.[68]

After the end of the Little Ice Age in 1850, the glaciers in the park retreated moderately until the 1910s. Between 1917 and 1941, the retreat rate accelerated and was as high as 330 ft (100 m) per year for some glaciers.[65] A slight cooling trend from the 1940s until 1979 helped to slow the rate of retreat and, in a few cases, even advanced the glaciers over ten meters. However, during the 1980s, the glaciers in the park began a steady period of loss of glacial ice, which continues as of 2010. In 1850, the glaciers in the region near Blackfoot and Jackson Glaciers covered 5,337 acres (21.6 km2), but by 1979, the same region of the park had glacier ice covering only 1,828 acres (7.4 km2). Between 1850 and 1979, 73% of the glacial ice had melted away.[69] At the time the park was created, Jackson Glacier was part of Blackfoot Glacier, but the two have separated into individual glaciers since.[70]

It is unknown how glacial retreat may affect the park's ecosystems beyond the broad concept of creating new problems over time, and intensifying or exacerbating existing challenges.[71] There is concern over negative impacts, such as the loss of habitat for plant and animal species that are dependent on cold water. Less glacial melt reduces stream level flow during the dry summer and fall seasons, and lowers water table levels overall, increasing the risk of forest fires. The loss of glaciers will also reduce the aesthetic appeal that glaciers provide to visitors.[69] Relative to the unpredictability of emerging science, misinformation began to circulate in the news media and on social media in early to mid-2019, claiming that the Park Service had discreetly removed or changed placards, movies, brochures, and other literature warning that the park's glaciers would be gone by 2020.[72][73] Apparently, the event was triggered when the Park Service began updating their on-site placards to reflect the latest scientific findings. The "gone by 2020" date on one placard was replaced with, "When they will completely disappear, however, depends on how and when we act." Another placard states, "Some glaciers melt faster than others, but one thing is consistent: the glaciers in the park are shrinking."[74]

### Climate

[edit]

The Big Drift covering the Going-to-the-Sun Road on March 23, 2006

As the park spans the Continental Divide, and has more than 7,000 ft (2,100 m) in elevation variance, many climates and microclimates are found in the park. As with other alpine systems, average temperature usually drops as elevation increases.[75] The western side of the park, in the Pacific watershed, has a milder and wetter climate, due to its lower elevation. Precipitation is greatest during the winter and spring, averaging 2 to 3 in (50 to 80 mm) per month. Snowfall can occur at any time of the year, even in the summer, and especially at higher altitudes. The winter can bring prolonged cold waves, especially on the eastern side of the Continental Divide, which has a higher elevation overall.[76] Snowfalls are significant over the course of the winter, with the largest accumulation occurring in the west. During the tourist season, daytime high temperatures average 60 to 70 °F (16 to 21 °C), and nighttime lows usually drop into the 40 °F (4 °C) range. Temperatures in the high country may be much cooler. In the lower western valleys, daytime highs in the summer may reach 90 °F (30 °C).[77]

Rapid temperature changes have been noted in the region. In Browning, Montana, just east of the park in the Blackfeet Reservation, a world record temperature drop of 100 °F (56 °C) in only 24 hours occurred on the night of January 23–24, 1916, when thermometers plunged from 44 to −56 °F (7 to −49 °C).[78]

Glacier National Park has a highly regarded global climate change research program. Based in West Glacier, with the main headquarters in Bozeman, Montana, the U.S. Geological Survey has performed scientific research on specific climate change studies since 1992. In addition to the study of the retreating glaciers, research performed includes forest modeling studies in which fire ecology and habitat alterations are analyzed. Additionally, changes in alpine vegetation patterns are documented, watershed studies in which stream flow rates and temperatures are recorded frequently at fixed gauging stations, and atmospheric research in which UV-B radiation, ozone, and other atmospheric gases are analyzed over time. The research compiled contributes to a broader understanding of climate changes in the park. The data collected, when compared to other facilities scattered around the world, help to correlate these climatic changes on a global scale.[79][80]

Glacier is considered to have excellent air and water quality. No major areas of dense human population exist anywhere near the region and industrial effects are minimized due to a scarcity of factories and other potential contributors of pollutants.[81] However, the sterile and cold lakes found throughout the park are easily contaminated by airborne pollutants that fall whenever it rains or snows, and some evidence of these pollutants has been found in park waters. Wildfires could also impact the quality of water. However, the pollution level is currently viewed as negligible, and the park lakes and waterways have a water quality rating of A-1, the highest rating given by the state of Montana.[82]

## Wildlife and ecology

[edit]

### Flora

[edit]

Beargrass is a tall flowering plant commonly found throughout the park.

Glacier is part of a large preserved ecosystem collectively known as the "Crown of the Continent Ecosystem", all of which is a primarily untouched wilderness of a pristine quality. Virtually all the plants and animals which existed at the time European explorers first entered the region are present in the park today.[85]

A total of over 1,132 plant species have been identified parkwide.[86] The predominantly coniferous forest is home to various species of trees such as the Engelmann spruce, Douglas fir, subalpine fir, limber pine and western larch, which is a deciduous conifer, producing cones but losing its needles each fall. Cottonwood and aspen are the more common deciduous trees and are found at lower elevations, usually along lakes and streams.[75] The timberline on the eastern side of the park is almost 800 ft (244 m) lower than on the western side of the Continental Divide, due to exposure to the colder winds and weather of the Great Plains. West of the Continental Divide, the forest receives more moisture and is more protected from the winter, resulting in a more densely populated forest with taller trees. Above the forested valleys and mountain slopes, alpine tundra conditions prevail, with grasses and small plants eking out an existence in a region that enjoys as little as three months without snow cover.[87] Thirty species of plants are found only in the park and surrounding national forests.[86] Beargrass, a tall flowering plant, is commonly found near moisture sources, and is relatively widespread during July and August. Wildflowers such as monkeyflower, glacier lily, fireweed, balsamroot and Indian paintbrush are also common.[88][89]

The forested sections fall into three major climatic zones. The west and northwest are dominated by spruce and fir and the southwest by red cedar and hemlock; the areas east of the Continental Divide are a combination of mixed pine, spruce, fir and prairie zones. The cedar-hemlock groves along the Lake McDonald valley are the easternmost examples of this Pacific climatic ecosystem.[90]

Whitebark pine communities have been heavily damaged due to the effects of blister rust, a non native fungus. In Glacier and the surrounding region, 30% of the whitebark pine trees have died and over 70% of the remaining trees are currently infected. The whitebark pine provides a high fat pine cone seed, commonly known as the pine nut, that is a favorite food of red squirrels and Clark's nutcracker. Both grizzlies and black bears are known to raid squirrel caches of pine nuts, one of the bears' favorite foods. Between 1930 and 1970, efforts to control the spread of blister rust were unsuccessful, and continued destruction of whitebark pines appears likely, with attendant negative impacts on dependent species.[91]

### Fauna

[edit]

See also: List of birds of Glacier National Park (U.S.) and Mammals of Glacier National Park (U.S.)

Over 1,000 grizzly bears live in the region as of 2021[update].[92]

Virtually all the historically known plant and animal species, with the exception of the bison and woodland caribou, are still present, providing biologists with an intact ecosystem for plant and animal research. Two threatened species of mammals, the grizzly bear and the lynx,[note 1] are found in the park.[50] Although their numbers remain at historical levels, both are listed as threatened because in nearly every other region of the U.S. outside of Alaska, they are either extremely rare or absent from their historical range. On average, one or two bear attacks on humans occur each year.[96] There have been 11 bear-related deaths since 1971, and 20 non-fatal injuries since 2001.[97] The exact number of grizzlies and lynx in the park is unknown;[50][98] however, the first ever scientific survey of the lynx population in the park was completed in 2021. The collected data will help researchers determine the number of individual lynx that populate certain areas of the park.[99] Reports from state and federal resource agencies, such as the Montana Department of Fish, Wildlife and Parks, indicate that as of 2021, the grizzly population throughout the millions of acres in and around Glacier Park has climbed to around 1,051–more than triple the 300 or so population estimates in 1975 when grizzlies were first listed as a threatened species.[92][100] While exact population numbers for grizzlies and the smaller black bear are still unknown, biologists have implemented a variety of methods in their efforts to achieve more accuracy in determining population range.[101] Another study has indicated that the wolverine, another very rare mammal in the lower 48 states, also lives in the park.[102] There were only three or four wolf packs remaining in the park when it was established. Early rangers used guns, traps, and poison to successfully eliminate the species from the park by 1936.[103] Wolves recolonized Glacier National Park naturally during the 1980s.[104] Sixty-two species of mammals have been documented including badger, river otter, porcupine, mink, marten, fisher, two species of marmots, six species of bats, and numerous other small mammals.[105] Other mammals such as the mountain goat (the official park symbol), bighorn sheep, moose, elk, mule deer, skunk, white-tailed deer, bobcat, coyote, and cougar are either plentiful or common.[105]

A marmot above Hidden Lake

Over 260 species of birds have been recorded, with raptors such as the bald eagle, golden eagle, peregrine falcon, osprey and several species of hawks residing year round.[106] The harlequin duck is a colorful species of waterfowl found in the lakes and waterways. The great blue heron, tundra swan, Canada goose and American wigeon are species of waterfowl more commonly encountered in the park. Great horned owl, Clark's nutcracker, Steller's jay, pileated woodpecker and cedar waxwing reside in the dense forests along the mountainsides, and in the higher altitudes, the ptarmigan, timberline sparrow and rosy finch are the most likely to be seen.[106][107] The Clark's nutcracker is less plentiful than in past years due to the decline in the number of whitebark pines.[91]

Because of the colder climate, ectothermic reptiles are all but absent, with two species of garter snake and the western painted turtle being the only three reptile species proven to exist.[108] Similarly, only six species of amphibians are documented, although those species exist in large numbers. After a forest fire in 2001, a few park roads were temporarily closed the following year to allow thousands of western toads to migrate to other areas.[109]

A total of 23 species of fish reside in park waters, and native game fish species found in the lakes and streams include the westslope cutthroat trout, northern pike, mountain whitefish, kokanee salmon and Arctic grayling. Glacier is also home to the threatened bull trout, which is illegal to possess and must be returned to the water if caught inadvertently.[110] Introduction in previous decades of lake trout and other non-native fish species has greatly impacted some native fish populations, especially the bull trout and west slope cutthroat trout.[111]

### Fire ecology

[edit]

Wildfires burned 13% of the park in 2003.

Forest fires were viewed for many decades as a threat to protected areas such as forests and parks. As a better understanding of fire ecology developed after the 1960s, forest fires were understood to be a natural part of the ecosystem. The earlier policies of suppression resulted in the accumulation of dead and decaying trees and plants, which would normally have been reduced had fires been allowed to burn. Many species of plants and animals actually need wildfires to help replenish the soil with nutrients and to open up areas that allow grasses and smaller plants to thrive.[112] Glacier National Park has a fire management plan which ensures that human-caused fires are generally suppressed. In the case of natural fires, the fire is monitored and suppression is dependent on the size and threat the fire may pose to human safety and structures.[113]

Increased population and the growth of suburban areas near parklands, has led to the development of what is known as Wildland Urban Interface Fire Management, in which the park cooperates with adjacent property owners in improving safety and fire awareness. This approach is common to many other protected areas. As part of this program, houses and structures near the park are designed to be more fire resistant. Dead and fallen trees are removed from near places of human habitation, reducing the available fuel load and the risk of a catastrophic fire, and advance warning systems are developed to help alert property owners and visitors about forest fire potentials during a given period of the year.[114] Glacier National Park has an average of 14 fires with 5,000 acres (20 km2) burnt each year.[115] In 2003, 136,000 acres (550 km2) burned in the park after a five-year drought and a summer season of almost no precipitation. This was the most area transformed by fire since the creation of the park in 1910.[116]

## Recreation

[edit]

Glacier National Park Red Jammer bus

Glacier is distant from major cities. The closest airport is in Kalispell, Montana, southwest of the park. Amtrak's Empire Builder stops seasonally at East Glacier, and year-round at West Glacier and Essex. A fleet of restored 1930s White Motor Company coaches, called Red Jammers, offer tours on all the main roads in the park. The drivers of the buses are called "Jammers", due to the gear-jamming that formerly occurred during the vehicles' operation. The tour buses were rebuilt in 2001 by Ford Motor Company. The bodies were removed from their original chassis and built on modern Ford E-Series van chassis.[117] They were also converted to run on propane to lessen their environmental impact.[118] Later, new hybrid engines were adopted.[119] As of 2017[update], 33 of original 35 are still in operation.[120]

Historic wooden tour boats, some dating back to the 1920s, operate on some of the larger lakes. Several of these boats have been in continuous seasonal operation at Glacier National Park since 1927 and carry up to 80 passengers. Three of these decades-old boats were added to the National Register of Historic Places in January 2018.[121]

Hiking is popular in the park. Over half of the visitors to the park report taking a hike on the park's nearly 700 mi (1,127 km) of trails.[122] 110 mi (177 km) of the Continental Divide National Scenic Trail spans most of the distance of the park north to south, with a few alternative routes at lower elevations if high altitude passes are closed due to snow. The Pacific Northwest National Scenic Trail crosses the park on 52 mi (84 km) from east to west.[123]

Many day hikes can be taken in the park. Back-country camping is allowed at campsites along the trails. A permit is required and can be obtained from certain visitor centers or arranged for in advance. Much of Glacier's backcountry is usually inaccessible to hikers until early June due to accumulated snowpack and avalanche risk, and many trails at higher altitudes remain snow-packed until July.[124] Campgrounds that allow vehicle access are found throughout the park, most of which are near one of the larger lakes. The campgrounds at St. Mary and at Apgar are open year-round, but conditions are primitive in the off-season, as the restroom facilities are closed and there is no running water. All campgrounds with vehicle access are usually open from mid-June until mid-September.[125] Guide and shuttle services are also available.[40]

The park attracts many mountain climbers, with many routes having rapid elevation gains. The mountains' sedimentary rocks fracture easily.[126] The Glacier Mountaineering Society sponsors climbing in the park and catalogues its peaks.[127]

The park is a popular destination for kayaking and fly fishing.[128] A permit is not required to fish in park waters. The threatened bull trout must be released immediately back to the water if caught; otherwise, the regulations on limits of catch per day are liberal.[129][47]

Winter recreation in Glacier is limited. Snowmobiling is illegal throughout the park. Cross-country skiing is permitted in the lower altitude valleys away from avalanche zones.[130]
