Birch Creek (Yukon River Tributary)
Birch Creek is a tributary of the Yukon River in the U.S. state of Alaska. Beginning at the confluence of Ptarmigan and Eagle creeks near Porcupine Dome, it flows southwest, then south under the Steese Highway and into the Steese National Conservation Area. It then turns east, then north, again passing under the Steese Highway and entering the Yukon Flats National Wildlife Refuge. Turning northwest, it ends where it splits into two distributaries, Lower Mouth Birch Creek and Upper Mouth Birch Creek, near Birch Creek, Alaska. The distributaries flow into the Yukon River at separate locations downstream of Fort Yukon. History The first human inhabitants of the region were probably Gwich'in people who hunted and fished along the creek. Gold was found along the creek in 1893. Circle City sprang up as the Alaska Interior's first gold town, governed democratically by traditional miners' meetings. Old mining and trapping cabins are part of the Birch Creek landscape, and mining continu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wild And Scenic Rivers Of The United States
The National Wild and Scenic Rivers System was created by the Wild and Scenic Rivers Act of 1968 (Public Law 90-542), enacted by the U.S. Congress to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition for the enjoyment of present and future generations. The Act is notable for safeguarding the special character of these rivers, while also recognizing the potential for their appropriate use and development. It encourages river management that crosses political boundaries and promotes public participation in developing goals for river protection. The Act, signed into law by President Lyndon B. Johnson in the height of the United States environmental era, states:"It is hereby declared to be the policy of the United States that certain selected rivers of the Nation which, with their immediate environments, possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic, cultural or other similar ...

Rivers Of Yukon–Koyukuk Census Area, 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, ...

Mushing
Mushing is a sport or transport method powered by dogs. It includes carting, pulka, dog scootering, sled dog racing, skijoring, freighting, and weight pulling. More specifically, it implies the use of one or more dogs to pull a sled, most commonly a specialized type of dog sled on snow, or a rig on dry land. History The practice of using dogs to pull sleds dates back to at least 6000 BC. Remnants of sleds and harnesses has been found with canine remains in Siberia which carbon-dated to 7800–8000 years ago. Native American cultures also used dogs to pull loads. In 1534, Jacques Cartier discovered the Gaspé Peninsula and claimed the land in the name of Francis I of France. For the better part of a century the Iroquois and French clashed in a series of attacks and reprisals. For this reason, Samuel de Champlain arranged to have young French men live with the natives, to learn their language and customs and help the French adapt to life in North America. These men, known as (ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukon Quest
The Yukon Quest, formally the Yukon Quest 1,000-mile International Sled Dog Race is a sled dog race scheduled every February since 1984 between Fairbanks, Alaska, and Whitehorse, Yukon. Because of the harsh winter conditions, difficult trail, and the limited support that competitors are allowed, it is considered the "most difficult sled dog race in the world", or even the "toughest race in the world"—"even tougher, more selective and less attention-seeking than the Iditarod Trail Sled Dog Race." The originator envisioned it as "a race so rugged that only purists would participate." In the competition, first run in 1984, a dog team leader (called a musher) and a team of 6 to 14 dogs race for 10 to 20 days. The course follows the route of the historic 1890s Klondike Gold Rush, mail delivery, and transportation routes between Fairbanks, Dawson City, and Whitehorse. Mushers pack up to of equipment and provisions for themselves and their dogs to survive between checkpoint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukon Flats
The Yukon Flats are a vast area of wetlands, forest, bog, and low-lying ground centered on the confluence of the Yukon River, Porcupine River, and Chandalar River in the central portion of the U.S. state of Alaska. The Yukon Flats are bordered in the north by the Brooks Range, in the south by the White Mountains, and cover an area of approximately . The Yukon Flats are a critical waterfowl breeding ground due to the large area of wetland provided by the estimated 40,000 small lakes and streams in the area. In recognition of this fact, the area is protected under the Yukon Flats National Wildlife Refuge. The Yukon Flats straddle the Arctic Circle and have an extremely variable climate. Temperatures of 95 F (35 °C) are not uncommon in summer, while winter temperatures have been known to drop to -70 F (-57 °C). Several hundred Alaska Natives and others live in the Yukon Flats area. Though most of the region's people are concentrated in the villages of Fort Yukon, Venetie, Beave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxbow Lake
An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. In South Texas, oxbows left by the Rio Grande are called '' resacas''. In Australia, oxbow lakes are called billabongs. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Because oxbow lakes are stillwater lakes, with no current flowing through them, the entire lake gradually silts up, becoming a bog or swamp and then evaporating completely. When a river reaches a low-lying plain, often in its final course to the sea or a lake, it meanders wi ... [...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 emanates ...

Northern Pike
The northern pike (''Esox lucius'') is a species of carnivorous fish of the genus '' Esox'' (the pikes). They are typical of brackish and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike in Britain, Ireland, and most of Eastern Europe, Canada and the United States. Pike can grow to a relatively large size: the average length is about , with maximum recorded lengths of up to and published weights of . The IGFA currently recognizes a pike caught by Lothar Louis on Greffern Lake, Germany, on 16 October 1986, as the all-tackle world-record northern pike. Northern pike grow to larger sizes in Eurasia than in North America, and typically grow to larger sizes in coastal than inland regions of Eurasia. Etymology The northern pike gets its common name from its resemblance to the pole-weapon known as the pike (from the Middle English for 'pointed'). Various other unofficial trivial names are common pike, Lakes pike, great n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
