Sheenjek River
The Sheenjek River is a tributary of the Porcupine River in the U.S. state of Alaska. It begins in the eastern part of the Brooks Range and flows southward to meet the larger river northeast of Fort Yukon. Its name derives from the Gwich'in word "khiinjik," meaning " dog-salmon river"." Explorer J.H. Turner called it the Salmon River. In the United States, the geographic location most remote from human trails, roads, or settlements is found here, at the headwaters of the Sheenjek River. Boating The Sheenjek is suitable for boating by wide variety of watercraft between June and late September. The upper river is rated mostly Class II (medium) on the International Scale of River Difficulty, while the lower half of the river is Class I (easy). However, just after rainstorms, the river can suddenly rise and become more difficult. Dangers on the upper river include shallow, extremely braided channels, and aufeis. Overhanging vegetation and submerged logs pose risks along the entire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukon Flats National Wildlife Refuge
The Yukon Flats National Wildlife Refuge is a protected wetland area in the U.S. state of Alaska. It encompasses most of the Yukon Flats, a vast wetland area centered on the confluence of the Yukon River, Porcupine River, and Chandalar River. The area is a major waterfowl breeding ground, and after a proposal to flood the Yukon Flats via a dam on the Yukon River was turned down, the Yukon Flats were deemed worthy of protection. On 1 December 1978, US President Jimmy Carter designated the Yukon Flats as a National Monument on the basis of the Antiquities Act of 1906. In the course of the Alaska National Interest Lands Conservation Act of December 2, 1980, the area boundaries were changed after political criticism and the status was downgraded to that of a wildlife refuge. It is the third-largest National Wildlife Refuge in the United States, although it is less than one-half the size of either of the two largest, the Arctic National Wildlife Refuge, or the Yukon Delta National ...

Chum Salmon
The chum salmon (''Oncorhynchus keta''), also known as dog salmon or keta salmon, is a species of anadromous salmonid fish from the genus '' Oncorhynchus'' (Pacific salmon) native to the coastal rivers of the North Pacific and the Beringian Arctic, and is often marketed under the trade name silverbrite salmon in North America. The English name "chum salmon" comes from the Chinook Jargon term ''tzum'', meaning "spotted" or "marked"; while ''keta'' in the scientific name comes from Russian, which in turn comes from the Evenki language of Eastern Siberia. In Japan, chum salmon is also known as the , or simply , while historically it was known in ''kun'yomi'' as up until the Meiji period. In Greater China, it is known academically as the " hook-snout salmon" ( zh, 钩吻鲑), but is more often called the ''damaha'' fish (), which is borrowed from ''dawa ịmaχa'', the Nanai name of the fish used by the Hezhe minority in northern Northeast China.

Tributaries Of The Yukon River
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Scott ...

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, ...

Aufeis
Aufeis, ( ), (German for "ice on top") is a sheet-like mass of layered ice that forms from successive flows of ground or river water during freezing temperatures. This form of ice is also called overflow, icings, or the Russian term, naled. The term was first used in 1859 by Alexander von Middendorff following his observations of the phenomenon in northern Siberia. When thawed, ''aufeis'' leave footprints in the form of ''aufeis'' glades or, perhaps more accurately in tundra habitats, “''aufeis'' barrens, because of the near absence of vascular plants due to ice cover during much of the growing season. Etymology Aufeis literally translates from German to “on ice”. In 1859 the Baltic German scientist and explorer Alexander von Middendorff used this term to describe his observations of the phenomenon in northern Siberia.Ashton, George D. 1986.
