Crow Creek (Alaska)
Crow Creek is a stream in the Chugach Mountains, Alaska, US. It is the only notable tributary of Glacier Creek (Turnagain Arm), Glacier Creek, which enters Turnagain Arm from the north, from its eastern end. The stream is notable as the site of ongoing gold mining since the late 19th century. Geography Crow Creek is a tributary of Glacier Creek, about above its mouth. The latter flows into Turnagain Arm from the northern side. The mountains at its head are high and rugged and form the divide between the waters that flow to Turnagain Arm and those tributary to Knik Arm. They are broken at the head of Crow Creek by Crow Creek Pass at an altitude of about , which affords a fairly good route from Crow Creek to Raven Creek, a tributary of Eagle River (Cook Inlet), Eagle River. From its source in the pass to its mouth, Crow Creek is about long. Near its head, it is precipitous, descending in waterfalls and rapids for a vertical distance of over within of the pass. It is fed by sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes th ...

Chugach Mountains
The Chugach Mountains of southern Alaska are the northernmost of the several mountain ranges that make up the Pacific Coast Ranges of the western edge of North America. The range is about long and wide, and extends from the Knik and Turnagain Arms of the Cook Inlet on the west to Bering Glacier, Tana Glacier, and the Tana River on the east. It is bounded on the north by the Matanuska, Copper, and Chitina rivers. The highest point of the Chugach Mountains is Mount Marcus Baker, at , but with an average elevation of , most of its summits are not especially high. Even so, its position along the Gulf of Alaska ensures more snowfall in the Chugach than anywhere else in the world, an annual average of over 1500 cm (800 in).Steep, Freeskiing Documentary, 2007 The mountains are protected in the Chugach State Park and the Chugach National Forest. Near to Anchorage, they are a popular destination for outdoor activities. The Richardson Highway, Seward Highway, Portage G ...

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 ...

Turnagain Arm
Turnagain Arm ( Dena'ina: ''Tutl'uh'') is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches at the north end of Cook Inlet, the other being Knik Arm. Turnagain is subject to climate extremes and large tide ranges. Geography Turnagain extends in an east-west direction, and is between long. It forms part of the northern boundary of Kenai Peninsula, and reaches on the east to within of Passage Canal, a western branch of Prince William Sound. Turnagain is characterized by remarkably large tides of up to 40 feet (12 meters) which are the largest tides in the United States. The flood tide often begins with a tidal bore especially on large tides with a strong east wind, which has a height of at times, and runs in from the west at a speed of an hour. At low tide, the arm becomes a broad mud flat, cut by the stream channels. Historically small steamers entered and left on high water though the practice is rare at best since most if not all the ...

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raven Glacier From Crow Pass
A raven is any of several larger-bodied bird species of the genus '' Corvus''. These species do not form a single taxonomic group within the genus. There is no consistent distinction between " crows" and "ravens", common names which are assigned to different species chiefly on the basis of their size. The largest raven species are the common raven and the thick-billed raven. Etymology The term "raven" originally referred to the common raven (''Corvus corax''), the type species of the genus ''Corvus'', which has a larger distribution than any other species of ''Corvus'', ranging over much of the Northern Hemisphere. The modern English word ''raven'' has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) and Old High German , all of which descend from Proto-Germanic . Collective nouns for a group of ravens (or at least the common raven) include "rave", "treachery", "unkindness" and "conspiracy". In practice, most people use the ...

Knik Arm
Knik Arm ( Dena'ina: ''Nuti'') is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches of Cook Inlet, the other being Turnagain Arm. Knik Glacier empties into the Knik Arm. The Port of Anchorage is located on the arm. Etymology The Dena'ina name for Knik Arm is ''Nuti'', meaning "salt water". The name "Knik" comes from ''igniq'', the Iñupiaq word for "fire". It has been written Kinik, Kneep, Kneik, Kook, Knuyk, and Kweek. Geography Knik Arm begins at the Inlet's northern edge, near Anchorage, before heading north and east. It is about long, and at its upper end, receives the waters of the Matanuska River. West of Knik Arm is the delta of the Susitna River, the largest stream emptying into the inlet. At the head of Knik Arm, at the mouth of Knik River, was the village (ghost town) of Knik. Knik Arm's other major tributaries are Ship Creek, Eagle River, Peter's Creek, Eklutna River and Fish Creek. The greater part of the plain, ...

Eagle River (Cook Inlet)
The Eagle River is a stream, long, in Anchorage, Alaska. Heading at Eagle Glacier in Chugach State Park, it flows northwest into Eagle Bay on the Knik Arm of Cook Inlet, northeast of downtown Anchorage. Course Beginning at Eagle Glacier in Chugach State Park, the river soon intersects the Iditarod National Historic Trail, which follows the Eagle River Valley from near Crow Pass in Chugach National Forest to the community of Eagle River. Downstream of the trail crossing, the river flows by, but at considerable distance from, the Eagle River Nature Center, the visitor center for the park. The nature center lies along the North Fork Eagle River, which runs roughly parallel to the main stem for several miles. Eagle River Road, like the North Fork, lies to the right of the main stem, facing downstream. Eagle River Road links the visitor center to the Eagle River community away. After receiving the North Fork from the right, the Eagle River receives the South Fork Eagle River f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluvioglacial Deposits
Glaciofluvial deposits or Glacio-fluvial sediments consist of boulders, gravel, sand, silt and clay from ice sheets or glaciers. They are transported, sorted and deposited by streams of water. The deposits are formed beside, below or downstream from the ice. They include kames, kame terraces and eskers formed in ice contact and outwash fans and outwash plains below the ice margin. Typically the outwash sediment is carried by fast and turbulent fluvio-glacial meltwater streams, but occasionally it is carried by catastrophic outburst floods. Larger elements such as boulders and gravel are deposited nearer to the ice margin, while finer elements are carried farther, sometimes into lakes or the ocean. The sediments are sorted by fluvial processes. They differ from glacial till, which is moved and deposited by the ice of the glacier, and is unsorted. Ice-contact deposits A subglacial megaflood may cut cavities into the base of the ice. As the flood dies down, sediment is deposited ...

Girdwood, Alaska
Girdwood is a resort town within the southern extent of the Municipality of Anchorage in the U.S. state of Alaska. Located near the end of the Turnagain Arm of Cook Inlet, Girdwood lies in a valley in the southwestern Chugach Mountains, surrounded by seven glaciers feeding into a number of creeks, which either converge within the valley or empty directly into the arm. Girdwood is typically accessed by the Seward Highway (Milepost 90), with the main line of the Alaska Railroad paralleling the highway. By road distance, most of the community lies within of Downtown Anchorage. The 2019 American Community Survey estimates a population of 1,742 in the valley. Founded as a community to supply miners during the Turnagain Arm gold rushes of the 1890s, Girdwood was mostly a small, quiet place until the middle of the 20th century. Two events drastically altered that. The first was the establishment of Alyeska Resort along the slopes of Mount Alyeska, which became an international des ...
