Arrigetch Peaks
The Arrigetch Peaks (Iñupiaq language, Iñupiaq: ''Argaich'') are a cluster of rugged granite spires in the Endicott Mountains of the central Brooks Range in northern Alaska. The name ''Arrigetch'' means 'fingers of the outstretched hand' in the Inupiat language, Inupiat language. The peaks ring the glacial cirques at the head of the Kobuk River and 2 tributaries of the Alatna River: Arrigetch Creek and Aiyagomahala Creek (Creek 4662). They are located at latitude 67 degrees 24' N and longitude 154 degrees 10' W. All of the summits of the peaks are around 6,000 ft, 1825 m elevation. The Arrigetch Peaks area was designated as a National Natural Landmark in 1968 for its spectacular geography. The earliest recorded Geological Survey of the area was in 1911 by Philip Sidney Smith, Philip S. Smith and H.M. Eakin. The renowned conservationist Bob Marshall (wilderness activist), Robert Marshall explored the area in the 1930s. These trips were described in Marshall's 1933 book ''Arc ...

Iñupiaq Language
Iñupiaq Iñupiaq : , Inupiaq, Iñupiat , Inupiat, Iñupiatun or Alaskan Inuit is an Inuit language, or perhaps languages, spoken by the Iñupiat people in northern and northwestern Alaska, as well as a small adjacent part of the Northwest Territories of Canada. The Iñupiat language is a member of the Inuit-Yupik-Unangan language family, and is closely related to, but not mutually intelligible with, other Inuit languages of Canada and Greenland. There are roughly 2,000 speakers. Iñupiaq is considered to be a threatened language, with most speakers at or above the age of 40. Iñupiaq is an official language of the State of Alaska, along with several other indigenous languages. The major varieties of the Iñupiaq language are the North Slope Iñupiaq and Seward Peninsula Iñupiaq dialects. The Iñupiaq language has been in decline since contact with English in the late 19th century. American territorial acquisition and the legacy of boarding schools have created a situation ...

Endicott Mountains
The Endicott Mountains are a range of mountains, part of the Brooks Range in northern Alaska. They are located in the middle of the Brooks range and run some east–west. To the east are the Philip Smith Mountains and to the west are the Schwatka Mountains. The Endicott Mountains are separated from the Philip Smith Mountains by the Middle Fork of the Koyukuk River, the Dalton Highway, and Atigun Pass. The Endicott Mountains are separated from the Schwatka Mountains by Walker Lake, the upper reaches of the West Fork of the Kobuk River (Kaluluktok Creek), Akabluak Pass, and the Noatak River. The Endicott Mountains are separated from the mountains north of the Schwatka by Lucky Six Creek, Gull Pass, Gull Creek, a portion of the Alatna River and the Killik River. From south to north the Endicott Mountains present long, broad glaciated valleys with rounded hills between rising in the center of the range to steep tors and aretes. The northern slopes of the Endicotts are steeper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooks Range
The Brooks Range ( Gwich'in: ''Gwazhał'') is a mountain range in far northern North America stretching some from west to east across northern Alaska into Canada's Yukon Territory. Reaching a peak elevation of on Mount Isto, the range is believed to be approximately 126 million years old. In the United States, these mountains are considered a subrange of the Rocky Mountains, whereas in Canada they are considered separate, as the northern border of the Rocky Mountains is considered to be the Liard River far to the south in the province of British Columbia. While the range is mostly uninhabited, the Dalton Highway and Trans-Alaska Pipeline System run through the Atigun Pass (1,415 m, 4,643 ft) on their way to the oil fields at Prudhoe Bay on Alaska's North Slope. The Alaska Native villages of Anaktuvuk and Arctic Village, as well as the very small communities of Coldfoot, Wiseman, Bettles, and Chandalar, are the range's only settlements. In the far west, near the Wul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Cirques
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Alatna River
The Alatna River is a federally designated wild and scenic river partially contained within the boundaries of Gates of the Arctic National Park, Alaska. It is called one of the most beautiful rivers in the United States. Geography The Alatna River stems from the central Brooks Range flowing through the Endicott Mountains, passing Circle Lake, the Arrigetch Peaks and Takahula Lake before entering the Helpmejack Hills. The last section of the river continues to flow in a SSE direction through the Alatna Hills into its confluence with the Koyukuk River near the small village of Allakaket. The first of the Alatna are shallow and rocky, followed by of a continued shallow area with more rapids. The river then mellows out near Takahula and Circle Lake becoming deeper and more meandering while the scenery turns from mountain peaks into hilly boreal forest. According to ''The Alaska River Guide'', this river is long from the headwaters to Allakaket and from Circle Lake to Allakaket. ...

National Natural Landmark
The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall. The program aims to encourage and support voluntary preservation of sites that illustrate the geological and ecological history of the United States. It also hopes to strengthen the public's appreciation of the country's natural heritage. As of January 2021, 602 sites have been added to the National Registry of Natural Landmarks. The registry includes nationally significant geological and ecological features in 48 states, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands. The National Park Service administers the NNL Program and if reques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bob Marshall (wilderness Activist)
Robert Marshall (January 2, 1901November 11, 1939) was an American forester, writer and wilderness activist who is best remembered as the person who spearheaded the 1935 founding of the Wilderness Society in the United States. Marshall developed a love for the outdoors as a young child. He was an avid hiker and climber who visited the Adirondack Mountains frequently during his youth, ultimately becoming one of the first Adirondack Forty-Sixers. He also traveled to the Brooks Range of the far northern Alaskan wilderness. He wrote numerous articles and books about his travels, including the bestselling 1933 book '' Arctic Village.'' A scientist with a PhD in plant physiology, Marshall became independently wealthy after the death of his father in 1929. He had started his outdoor career in 1925 as forester with the U.S. Forest Service. He used his financial independence for expeditions to Alaska and other wilderness areas. Later he held two significant public appointed posts: chie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Alaska
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
