Itkillik River
The Itkillik River is a tributary of the Colville River in the North Slope Borough of the U.S. state of Alaska. The river flows northeast then northwest out of the Endicott Mountains near Oohlah Pass to meet the larger stream about southwest of Harrison Bay on the Beaufort Sea. An Iñupiaq map, drawn in about 1900, identifies the river as ''It-kil-lik'', meaning ''Indian''. A melting permafrost formation exposed along the Itkillik River is the largest known yedoma in Alaska. The formation, deposited between 50,000 and 10,000 years ago, contains remains of bison, muskoxen, mammoths, and other animals embedded in an ice cliff that is high and long. The ice is rich in methane. Odors emitted by the gasses released when the ice thaws have led to the site's nickname, the ''Stinking Hills'' or ''Stinky Bluffs''.

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 ...

North Slope Borough, Alaska
The North Slope Borough is the northernmost borough in the US state of Alaska and thus, the northernmost county or equivalent of the United States as a whole. As of the 2020 census, the population was 11,031. The borough seat and largest city is Utqiaġvik (known as Barrow from 1901 to 2016), which is also the northernmost settlement in the United States. History The borough was established in 1972 by an election of the majority Indigenous people in the region, following Congressional passage of the Alaska Native Claims Settlement Act. Most are Inupiat. The borough was named for the Alaska North Slope basin. In 1974 it adopted a Home Rule Charter, enabling it to exercise any legitimate governmental power. The borough has first-class status and exercises the powers of planning, zoning, taxation, and schools."Your Government" North Slope ...

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] |
Google Earth

Colville River (Alaska)
The Colville River (; Inupiat: ''Kuukpik'') is a major river of the Arctic Ocean coast of Alaska in the United States, approximately long. One of the northernmost major rivers in North America, it drains a remote area of tundra on the north side of the Brooks Range entirely above the Arctic Circle. The river is frozen for more than half the year and floods each spring. It rises on the north slope of the De Long Mountains, at the western end of the Brooks Range, north of the continental divide in the southwestern corner of the National Petroleum Reserve. It flows initially north, then generally east through the foothills on the north side of the range, broadening as it receives the inflow of many tributaries that descend from the middle Brooks Range. Along its middle course it forms the southeastern border of the National Petroleum Reserve. At the Iñupiat village of Umiat it turns north to flow across the Arctic plain, entering the western Beaufort Sea in a broad delta near Nuiq ...

Beaufort Sea
The Beaufort Sea (; french: Mer de Beaufort, Iñupiaq: ''Taġiuq'') is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, and west of Canada's Arctic islands. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores. The sea, characterized by severe climate, is frozen over most of the year. Historically, only a narrow pass up to opened in August–September near its shores, but recently due to climate change in the Arctic the ice-free area in late summer has greatly enlarged. Until recently, the Beaufort Sea was known as an important reservoir for the replenishment of Arctic sea ice. Sea ice would often rotate for several years in the Beaufort Gyre, the dominant ocean current of the Beaufort Sea, growing into sturdy and thick multi-year i ...

Yedoma
Yedoma (russian: едома) is an organic-rich (about 2% carbon by mass) Pleistocene-age permafrost with ice content of 50–90% by volume. Yedoma are abundant in the cold regions of eastern Siberia, such as northern Yakutia, as well as in Alaska and the Yukon. Characteristics The landscape of Yedoma areas is of glacier plains and hills with shallow depressions known as alas. Yedoma usually form in lowlands or stretches of land with rolling hills where ice wedge polygonal networks are present, in stable relief features with accumulation zones of poor drainage, severe cold and arid continental climate zones resulting in scanty vegetation cover, intense periglacial weathering processes, as well as the proximity of sediment sources, such as low mountain ranges and foothills. The amount of carbon trapped in this type of permafrost is much more prevalent than originally thought and may be about 210 to 500 Gt, that is a multiple of the amount of carbon released into the air each ye ...

Rivers Of North Slope Borough, Alaska
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...
