Gates of the Arctic National Park and Preserve is a national park of the United States that protects portions of the Brooks Range in northern Alaska. The park is the northernmost national park in the United States, situated entirely north of the Arctic Circle. The area of the park and preserve is the second largest in the U.S. at 8,472,506 acres (13,238 sq mi; 34,287 km2); the National Park portion is the second largest in the U.S., after the National Park portion of Wrangell–St. Elias National Park and Preserve.
Gates of the Arctic was initially designated as a national monument on December 1, 1978, before being redesignated as a national park and preserve upon passage of the Alaska National Interest Lands Conservation Act in 1980. About 85% of the park has additional protection as the Gates of the Arctic Wilderness which covers 7,167,192 acres (2,900,460 ha). [3] The wilderness area adjoins the Noatak Wilderness. Together, they form the largest contiguous wilderness in the United States.
According to the National Park website: [4]
The purpose of Gates of the Arctic National Park and Preserve is to preserve the vast, wild, undeveloped character and environmental integrity of Alaska's central Brooks Range and to provide opportunities for wilderness recreation and traditional subsistence uses.
There are no roads or official trails in Gates of the Arctic National Park and Preserve. Owing to its remoteness and lack of supportive infrastructure, the park is the least visited national park in the U.S., [5] [6] and one of the least visited areas in the entire U.S. National Park System, which also includes national monuments, recreation areas, preserves, and historic sites. In 2021, the park received just 7,362 recreation visitors, while Grand Canyon National Park received about 4.5 million visitors (over 600 times as many) in the same year. [7]
Camping is permitted throughout the park, but may be restricted by easements when crossing Native Corporation lands within the park.
The park headquarters is in Fairbanks. [8] [9] Park Service operations in the park are managed from the Bettles Ranger Station, to the south of the park.
Gates of the Arctic National Park and Preserve lies to the west of the Dalton Highway, centered on the Brooks Range and covering the north and south slopes of the mountains. The park includes the Endicott Mountains and part of the Schwatka Mountains. The majority of Gates of the Arctic is designated as national park, in which only subsistence hunting by local rural residents is permitted. Sport hunting is only permitted in the national preserve. To hunt and trap in the preserve, a person must have all required licenses and permits and follow all other state regulations. [10]
The eastern boundary of the park generally follows the Dalton Highway at a distance of a few miles, with the westernmost part of the Arctic National Wildlife Refuge 10 miles (16 km) farther east. Kanuti National Wildlife Refuge is near the park's southeast boundary. Noatak National Preserve adjoins the western boundary, and the National Petroleum Reserve–Alaska adjoins the northwest corner of the park. Almost all of the park is designated as wilderness, with the exception of areas around Anaktuvuk Pass. A detached portion of the park surrounds the outlying Fortress Mountain and Castle Mountain to the north of the park. [11]
Ten small communities outside the park's boundaries are classified as "resident zone communities" and depend on park resources for food and livelihood. They are Alatna, Allakaket, Ambler, Anaktuvuk Pass, Bettles, Evansville, Hughes, Kobuk, Nuiqsut, Shungnak, and Wiseman. [12] There are no established roads, trails, visitor facilities, or campgrounds in the park. The Dalton Highway (Alaska State Highway 11) comes within five miles (8 km) of the park's eastern boundary, but requires a river crossing to reach the park from the road. [9] The Arctic Interagency Visitor Center in nearby Coldfoot is open from late May to early September, providing information on the parks, preserves and refuges of the Brooks Range, Yukon Valley and the North Slope. [13] About 259,000 acres (105,000 ha) of the park and preserve are owned by native corporations or the State of Alaska. 7,263,000 acres (2,939,000 ha) are protected in the Gates of the Arctic Wilderness, the third-largest designated wilderness area in the United States (after the Wrangell-Saint Elias Wilderness and the Mollie Beattie Wilderness, both also in Alaska). [14]
The park contains mountains such as the Arrigetch Peaks and Mount Igikpak. The park also features six Wild and Scenic Rivers:
According to the Köppen climate classification system, Gates of the Arctic National Park and Preserve has a Subarctic with Cool Summers and Year Around Rainfall Climate (Dfc). The plant hardiness zone at Anaktuvuk Pass Ranger Station is 2b with an average annual extreme minimum temperature of −42.6 °F (−41.4 °C). [15] Perennial snowfields and glaciers, which are crucial to various ecosystems within the park, are decreasing at a rapid rate due to warming temperatures. [16] From 1985 to 2017, the area of these snowfields decreased in size by 13 km2. [16] These warming temperatures have also resulted in the thawing of permafrost which has directly affected the stability of the soil. [17] As permafrost thaws, it exposes the bare soil to the elements which leads to erosion and slope failures. [18]
The park includes much of the central and eastern Brooks Range. It extends to the east as far as the Middle Fork of the Koyukuk River, which is paralleled by the Dalton Highway and the Trans-Alaska Pipeline. The park straddles the continental divide, separating the drainages of the Pacific and Arctic Oceans. The northernmost section of the park includes small portions of the Arctic foothills tundra. The Brooks Range occupies the central section of the park, running on an east-west line. To the south of the Brooks Range the Ambler-Chandalar Ridge runs east-west. Between the mountains are many remote glacier-carved valleys, dotted with alpine lakes.
The southernmost portion of the park includes the Kobuk-Selawik Lowlands, with the headwaters of the Kobuk River. The Brooks Range has seen repeated glaciation, with the most recent called the Itkillik glaciation from about 24,000 years ago to roughly 1500 to 1200 years before the present. [14]
The boreal forest extends to about 68 degrees north latitude, characterized by black and white spruce mixed with poplar. To the north of that line, which coincides with the spine of the Brooks Range, lies cold-arid land that has been described as "Arctic desert." During the long winters temperatures can reach −75 °F (−59 °C), but can reach 90 °F (32 °C) for a short time in summer. The park lies above the Arctic Circle. [14]
Fauna include brown bears, black bears, muskoxen, moose, Dall sheep, timber wolves, wolverines, coyotes, lynxes, Arctic ground squirrels, lemmings, voles, marmots, porcupines, river otters, red and Arctic fox species, beavers, wood frogs, snowshoe hares, collared pikas, muskrats, Arctic terns, bald eagles, golden eagles, peregrine falcons, ospreys, great horned and northern hawk-owls. [19] [20] The rivers contain a variety of fish species, including the grayling, Arctic char and chum salmon. Eagles and other birds of prey can be seen soaring overhead waiting for unsuspecting prey.
More than half a million caribou, including the Central Arctic, Western Arctic, Teshekpuk, and Porcupine herds, migrate through the central Brooks Range twice yearly, traveling north in summer, and south in winter. Caribou are important as a food source to native peoples. [21] However, the decreasing size of perennial snowfields within the park may decrease the size of this caribou population. [16] The park is the northernmost range limit for the Dall sheep. [22] About 132 brown bears reside in the park and preserve, based on a density of about one bear per 100 square miles (260 km2). [23] [24]
Nomadic peoples have inhabited the Brooks Range for as many as 12,500 years, living mainly on caribou and other wildlife. The Mesa site at Iteriak Creek has yielded evidence of occupation between 11,500 and 10,300 years before the present. Later sites from around 6,000 years before present have yielded projectile points, stone knives and net sinkers. The Arctic small tool tradition (ASTt) of about 4,500 BP has also been documented. A late phase of the ASTt from between 2500 and 950 BP, the Ipuitak phase, has been documented in the park at the Bateman Site at Itkillik Lake. [14]
The earliest Inupiat people appeared about 1200 AD at the coast and spread to the Brooks Range, becoming the Nunamiut. [14] The Nunamiut people, who had left much of their traditional homelands following a crash in the caribou populations in the early 1900s, resumed a relatively isolated subsistence way of life after returning to the mountains in the late 1930s. In 1949 the last two semi-nomadic bands came together in the valley of the Anaktuvuk River, and over the next decade established the community of Anaktuvuk Pass. [25] The Gwich'in people, a Northern Athabaskan group also lived in the area in the last 1000 years, moving south of the park in historic times. [14]
The Alaskan interior was not explored until the late 19th century, shortly before discovery of gold in the Klondike brought prospectors to Alaska. Some encampments of explorers and survey parties have been identified in the park. A few small mining operations were established in the early 20th century, never amounting to much. [14]
The park's name dates to 1929, when wilderness activist Bob Marshall, exploring the North Fork of the Koyukuk River, encountered a pair of mountains (Frigid Crags and Boreal Mountain), one on each side of the river. He christened this portal the "Gates of the Arctic." [26] Marshall spent time in Wiseman during the early 1930s, publishing an account of the place in his 1933 book Arctic Village . In the 1940s writer and researcher Olaus Murie proposed that Alaskan lands be preserved. [27]
Proposals for a national park in the Brooks Range first emerged in the 1960s, and in 1968 a National Park Service survey team recommended the establishment of a 4,100,000-acre (1,700,000 ha) park in the area. [25] That year, Secretary of the Interior Stewart Udall recommended to President Lyndon B. Johnson that Johnson use the Antiquities Act to proclaim a national monument in the Brooks Range and other Alaskan locations, but Johnson declined. During the 1970s the Alaska Native Claims Settlement Act (ANCSA) prompted serious examination of the disposition of lands held by the federal government. A series of bills were considered to deal with conservation land proposals authorized under ANCSA, but the legislation that would become the Alaska National Interest Lands Conservation Act (ANILCA) was held up in Congress in the late 1970s. Consequently, on December 1, 1978 President Jimmy Carter used the Antiquities Act to proclaim much of the proposed new Alaskan parklands as national monuments, including Gates of the Arctic National Monument. In 1980 Congress passed ANILCA, and the monument became Gates of the Arctic National Park and Preserve on December 2, 1980. [27]
The Arctic National Wildlife Refuge or Arctic Refuge is a national wildlife refuge in northeastern Alaska, United States, on traditional Iñupiaq and Gwich'in lands. The refuge is 19,286,722 acres (78,050.59 km2) of the Alaska North Slope region, with a northern coastline and vast inland forest, taiga, and tundra regions. ANWR is the largest national wildlife refuge in the country, slightly larger than the Yukon Delta National Wildlife Refuge. The refuge is administered from offices in Fairbanks. ANWR is home to a diverse range of endemic mammal species; notably, it is one of the few North American locations with all three endemic American bears—the polar bear, grizzly bear, and American black bear, each of which resides predominantly in its own ecological niche. Besides the bears, other mammal species include the moose, caribou, wolves, red and Arctic fox, Canada lynx, wolverine, pine marten, American beaver, and North American river otter. Further inland, mountain goats may be seen near the slope. Hundreds of species of migratory birds visit the refuge yearly, and it is a vital, protected breeding location for them. Snow geese, eiders and snowy owls may be observed as well.
Northwest Arctic Borough is a borough located in the U.S. state of Alaska. As of the 2020 census, the population was 7,793, up from 7,523 in 2010. The borough seat is Kotzebue. The borough was formed on June 2, 1986.
Yukon–Koyukuk Census Area is a census area in the U.S. state of Alaska. As of the 2020 census, the population was 5,343, down from 5,588 in 2010. With an area of 147,842.51 sq mi (382,910.3 km2), it is the largest of any county or county-equivalent in the United States, or slightly larger than the entire state of Montana. It is part of the unorganized borough of Alaska and therefore has no borough seat. Its largest communities are the cities of Galena, in the west, and Fort Yukon, in the northeast.
The Brooks Range is a mountain range in far northern North America stretching some 700 miles (1,100 km) from west to east across northern Alaska into Canada's Yukon Territory. Reaching a peak elevation of 8,976 feet (2,736 m) on Mount Isto, the range is believed to be approximately 126 million years old.
Denali National Park and Preserve, formerly known as Mount McKinley National Park, is a United States national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres which is larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. The park received 594,660 recreational visitors in 2018.
The Kobuk River, also known by the names Kooak, Kowak, Kubuk, Kuvuk, and Putnam, is a river located in the Arctic region of northwestern Alaska in the United States. It is approximately 280 miles (451 km) long. Draining a basin with an area of 12,300 square miles (32,000 km2), the Kobuk River is among the largest rivers in northwest Alaska, with widths of up to 1,500 feet and flows reaching speeds of 3–5 miles per hour in its lower and middle reaches. The average elevation for the Kobuk River Basin is 1,300 feet (400 m) above sea level, ranging from sea level at its mouth on the Bering Sea to 11,400 feet near its headwaters in the Brooks Range.
The Koyukuk River is a 425-mile (684 km) tributary of the Yukon River, in the U.S. state of Alaska. It is the last major tributary entering the Yukon before the larger river empties into the Bering Sea.
Kobuk Valley National Park is a national park of the United States in the Arctic region of northwestern Alaska, located about 25 miles (40 km) north of the Arctic Circle. The park was designated in 1980 by the Alaska National Interest Lands Conservation Act to preserve the 100 ft (30 m) high Great Kobuk Sand Dunes and the surrounding area which includes caribou migration routes. Park visitors must bring all their own gear for backcountry camping, hiking, backpacking, boating, and dog sledding. No designated trails or roads exist in the park, which at 1,750,716 acres, is slightly larger than the state of Delaware. Kobuk Valley is one of eight national parks in Alaska, the state with the second most national parks, surpassed only by California which has nine. The park is managed by the National Park Service.
Hotham Inlet, also known as Kobuk Lake, is an arm of Kotzebue Sound on the northwestern coast of the U.S. state of Alaska. It is 50 miles (80 km) long and 5–20 miles (8–32 km) wide. The inlet is the outlet of the Kobuk and Selawik Rivers and it is bounded on the southwest by the Baldwin Peninsula.
The Noatak River is a river in the northwestern part of the U.S. state of Alaska.
Noatak National Preserve is a United States National Preserve in northwestern Alaska that was established to protect the Noatak River Basin. The Noatak River system, located just north of the Arctic Circle, is thought to be the last remaining complete river system in the United States that has not been altered by human activities. The roadless basin was proclaimed a United States National Monument in 1978 and a National Preserve in 1980 through the passage of the Alaska National Interest Lands Conservation Act (ANILCA). Noatak National Preserve borders Kobuk Valley National Park on the south and Gates of the Arctic National Park on the east. Unlike the national parks that it borders, sport hunting is allowed in Noatak National Preserve.
Cape Krusenstern National Monument and the colocated Cape Krusenstern Archeological District is a U.S. National Monument and a National Historic Landmark centered on Cape Krusenstern in northwestern Alaska. The national monument was one of fifteen new National Park Service units designated by the Alaska National Interest Lands Conservation Act (ANILCA) of 1980. It was initially declared a national monument under the authority of the Antiquities Act by President Jimmy Carter on December 1, 1978.
The Alatna River is a federally designated wild and scenic river partially contained within the boundaries of Gates of the Arctic National Park, Alaska.
The John River (Iñupiaq: Atchiiniq) is a 125-mile (201 km) tributary of the Koyukuk River in the northern part of the U.S. state of Alaska. It was named after John Bremner, a prospector and explorer who was one of the first non-native persons to go there. It flows south from Anaktuvuk Pass in Alaska's Brooks Range, into the larger river at a point near Bettles, slightly north of the Arctic Circle.
The Anaktuvuk River is a river in Alaska's North Slope. One hundred and thirty-five miles (217 km) long, it flows west from glaciers in the Endicott Mountains changing direction just north of Anaktuvuk Pass to flow north to the Arctic Coastal Plain where it joins the Colville River. Its headwaters are formed by runoff from various glaciers in the Gates of the Arctic Wilderness on the slopes of Fan Mountain, Alapah Mountain and Limestack Mountain, the last of which lies on the watershed divide between the Arctic Coastal Plain and the Koyukuk River, and feeds the Anaktuvuk River via Graylime Creek. Its first major tributary is the John River which joins it at 68°12′14″N151°36′50″W. The Nanushuk River joins it at 69°18′11″N150°59′58″W.
The Nunamiut or Nunatamiut are semi-nomadic inland Iñupiat located in the northern and northwestern Alaskan interior, mostly around Anaktuvuk Pass, Alaska.
The North Fork of the Koyukuk River is one of the principal forks of the Koyukuk River, approximately 105 mi (160 km) long, in northern Alaska in the United States. It has a watershed area of 1,850 square miles (4,800 km2). It rises on the south slopes of the Continental Divide in the Brooks Range.
The Koyukuk National Wildlife Refuge is a 3,500,000-acre (14,000 km2) conservation area in Alaska. It lies within the floodplain of the Koyukuk River, in a basin that extends from the Yukon River to the Purcell Mountains and the foothills of the Brooks Range. This region of wetlands is home to fish, waterfowl, beaver and Alaskan moose, and wooded lowlands where two species of fox, bears, wolf packs, Canadian lynx and marten prowl.
The Brooks–British Range tundra is an ecoregion spanning North America and Canada, and is one of the WWF Global 200 ecoregions.
Mount Doonerak is a 7,457-foot-elevation (2,273-meter) mountain summit in Alaska, United States.
