Copper River Census Area, Alaska
Copper River Census Area is a census area located in the state of Alaska, United States. It is part of the Unorganized Borough and therefore has no borough seat. On January 2, 2019, it was split from the Valdez–Cordova Census Area, along with neighboring Chugach Census Area. As of the 2020 census, the census area had a population of 2,617; its largest communities are the census-designated places of Glennallen and Copper Center. It is named after Copper River that has rich fish and flows through the census area. Demographics According to the 2010 United States Census (in which it was reported as the "Copper River Census Subarea"), the census area had a population of 2,952; 2,229 (75.5%) of whom were over the age of 18, and 321 (10.9%) of whom were over the age of 65. 2,032 residents (68.8%) were reported as White alone (2,020/68.4% non-Hispanic white), 11 (0.4%) as Black, 678 (23.0%) as American Indian or Alaska Native, 11 (0.4%) as Asian, 13 (0.4%) as Native Hawa ...

Kuskulana River
Kuskulana River is a waterway in the U.S. state of Alaska. It is located in the Wrangell–St. Elias National Park and Preserve. Geography The stream has its source in Kuskulana Glacier at an elevation of about 2,200 feet. It flows southwestward for about 21 miles and joins Chitina River about 10 miles above the Copper at an elevation of approximately 600 feet, thus having an average grade of a little over 75 feet per mile. The main body of Kuskulana Glacier is about 11 miles long and slopes from east to west with an average width of about one-third mile. It receives four northern branches that emanate from the south and west slopes of Mount Blackburn. The basin above the Chitina Valley is exceedingly rugged. The snowfall in the higher mountains is said to be heavy, accumulating in massive drifts in the gulches and sheltered spots and in some places lasting throughout the summer. The river derives its main supply from Kuskulana Glacier and is heavily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Grayling
The Arctic grayling (''Thymallus arcticus'') is a species of freshwater fish in the salmon family Salmonidae. ''T. arcticus'' is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in lakes in the high Uinta Mountains in Utah, as well as alpine lakes of the Boulder Mountains (Idaho) in central Idaho. Taxonomy The scientific name of the Arctic grayling is ''Thymallus arcticus''. It was named in 1776 by German zoologist Peter Simon Pallas from specimens collected in Russia. The name of the genus ''Thymallus'' first given to grayling (''T. thymallus'') described in the 1758 edition of ''Systema Naturae'' by Swedish zoologist Carl Linnaeus originates from the faint smell of the herb thyme, which emana ...

Lake Trout
The lake trout (''Salvelinus namaycush'') is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called ''mud hens''. Taxonomy It is the only member of the subgenus ''Cristovomer'', which is more derived than the subgenus '' Baione'' (the most basal clade of ''Salvelinus'', containing the brook trout (''S. fontinalis'') and silver trout (''S. agasizii'')) but still basal to the other members of ''Salvelinus''. Range From a zoogeographical perspective, lake trout have a relatively narrow distribution. They are native only to the northern parts of North America, principally Canada, but also Alaska and, to some extent, the northeastern United States. Lake trout have been wid ...

Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent ex ...

Game Fish
Game fish, sport fish or quarry refer to popular fish pursued by recreational anglers, and can be freshwater or saltwater fish. Game fish can be eaten after being caught, or released after capture. Some game fish are also targeted commercially, particularly salmon and tuna. Specimens of game fish whose measurements (body length and weight) are a lot above the species' average are sometimes known as trophy fish. Examples The species of fish prized by anglers varies with geography and tradition. Some fish are sought for their value as food, while others are pursued for their fighting abilities, or for the difficulty of successfully enticing the fish to bite the hook. * Big-game fish are blue water saltwater bony fish such as tuna, tarpon, grouper and billfish ( sailfish, marlin and swordfish). Occasionally other predatory fishes such as sharks, barracuda and dolphinfish are also pursued. * In North America, many anglers fish for common snook, redfish, salmon/trout, ba ...

Salmon
Salmon () is the common name for several commercially important species of euryhaline ray-finned fish from the family Salmonidae, which are native to tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus '' Oncorhynchus'') basin. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen. Salmon are typically anadromous: they hatch in the gravel beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon. Homing behavior has been shown to depend on ...

Grizzly Bear
The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly (''Ursus arctos horribilis''), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (''U. a. middendorffi''), the Kamchatka bear (''U. a. beringianus''), and the peninsular grizzly (''U. a. gyas'')—as well as the extinct California grizzly (''U. a. californicus''†), Mexican grizzly (formerly ''U. a. nelsoni''†), and Ungava-Labrador grizzly (formerly ''U. a. ungavaesis''†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. The Ussuri brown bear (''U. a. lasiotus''), inhabiting Russia, Northern China, Japan, and Korea, is sometimes referred to as the "black grizzly", although it is no more clos ...

River Mouth
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

Whitewater
Whitewater forms in a rapid context, in particular, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that froths, making the water appear opaque and white. The term "whitewater" also has a broader meaning, applying to any river or creek that has a significant number of rapids. The term is also used as an adjective describing boating on such rivers, such as whitewater canoeing or whitewater kayaking. Fast rivers Four factors, separately or in combination, can create rapids: gradient, constriction, obstruction, and flow rate. Gradient, constriction, and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams. Streambed topography Streambed topography is the primary factor in creating rapids, and is generally consistent over time. Increase ...

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, ...
