Sheep Creek (Juneau, Alaska)
Sheep Creek is located southeast of Juneau, in the U.S. state of Alaska. The Juneau community of Thane was originally called Sheep Creek. Draining an area of about , it empties into Gastineau Channel. The valley formed by the river has a flat, gravel, trekking trail of , south of Mount Roberts. The Snettisham hydroelectric dam substation is situated on a trail spur. Sheep Creek Hatchery is located at the outflow. Geography Sheep Creek raises from the Sheep Mountain at an elevation of . Flowing from the water parting next to Grindstone Creek, the course of the main valley runs from southeast to northwest. About from its head, the stream makes a broad turn and in the lower , flows toward the southwest. The total length of the river valley is about . The upper and lower thirds of its course have steep grades, but the middle course is over a gravel flat sloping from elevation. Below the gravel flat, the tributary slopes are very narrow and there are no side gulches. Practically a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juneau
The City and Borough of Juneau, more commonly known simply as Juneau ( ; tli, Dzánti K'ihéeni ), is the capital city of the state of Alaska. Located in the Gastineau Channel and the Alaskan panhandle, it is a unified municipality and the second- largest city in the United States by area. Juneau was named the capital of Alaska in 1906, when the government of what was then the District of Alaska was moved from Sitka as dictated by the U.S. Congress in 1900. The municipality unified on July 1, 1970, when the city of Juneau merged with the city of Douglas and the surrounding Greater Juneau Borough to form the current municipality, which is larger by area than both Rhode Island and Delaware. Downtown Juneau () is nestled at the base of Mount Juneau and across the channel from Douglas Island. As of the 2020 census, the City and Borough had a population of 32,255, making it the third-most populous city in Alaska after Anchorage and Fairbanks. Juneau experiences a daily influx o ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Juneau Gold Belt
The Juneau gold belt is located in the southeastern portion of the U.S. state of Alaska. This belt is approximately in length, north/northwest-trending, and extends from Berners Bay southeastward to Windham Bay, southeast of Juneau, and includes Douglas Island. The belt contains over 200 gold-quartz-vein deposits with production nearing of gold. More than three-quarters of Alaska's lode gold was mined from the Juneau gold belt. History Gold mining in the belt became active after an 1869 study of the Juneau mining district, of which the Juneau gold belt is but one part. Chief Kowee was one of the earliest gold prospectors in the belt area. In 1880, he revealed to prospectors Joe Juneau and Richard Harris the presence of gold in Silver Bow Basin's Gold Creek, after which Juneau was founded in the same year. The Juneau gold rush of 1880 resulted in some of the largest gold mines in the world, including the Treadwell complex of lode mines on Douglas Island and the Alaska-June ...

Coho
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon or "silvers". The scientific species name is based on the Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and average and , occasionally reaching up to . They also develop a large kype (hooked beak) during spawning. Mature females may be darker than males, with both showing a pronounced hook on the nose. Rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oncorhynchus Keta
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 language, 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 "kype, hook-snout salmon" ( zh, 钩吻鲑), but is more often called the ''damaha'' fish (), which is loanword, borrowed from ''dawa ịmaχa'', the Nanai language, Nanai name of the fish used by the Nanai people, Hezhe minority in ...

American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Goats
The mountain goat (''Oreamnos americanus''), also known as the Rocky Mountain goat, is a hoofed mammal endemic to mountainous areas of western North America. A subalpine to alpine species, it is a sure-footed climber commonly seen on cliffs and ice. Despite its vernacular name and both genera being in the same subfamily (Caprinae), the mountain goat is not a member of ''Capra'', the genus that includes all other goats, such as the wild goat (''Capra aegagrus''), from which the domestic goat is derived. Instead, it is more closely allied with the takins (''Budorcas'') and chamois (''Rupicapra''). Classification and evolution The mountain goat is an even-toed ungulate of the order Artiodactyla and the family Bovidae (along with antelopes, gazelles, and cattle). It belongs to the subfamily Caprinae, along with true goats, wild sheep, the chamois, the muskox and other species. The takins of the Himalayan region, while not a sister lineage of the mountain goat, are nonetheless ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubus Spectabilis
''Rubus spectabilis'', the salmonberry, is a species of bramble in the rose family Rosaceae, native to the west coast of North America from west-central Alaska to California, inland as far as Idaho. Like many other species in the genus ''Rubus'', the salmonberry plant bears edible fruit, typically yellow-orange or red in color, resembling raspberries in appearance. Description ''Rubus spectabilis'' is a deciduous, rhizomatous shrub growing to tall and 9 metres (30 feet) wide, with a moderate growth rate of 0.3–06 metres (12-24 inches) per year. 30-40% of the plant's biomass is underground. It has perennial (not biennial) woody stems that are covered with fine prickles, especially on new growth. The plant has golden or yellowish brown erect or arching stems (also known as "canes") that often form thickets, like many other brambles in the genus ''Rubus''. The leaves are alternate, trifoliate (with three leaflets), long and typically ovate in shape, with the terminal leaflet b ...

Blueberry
Blueberries are a widely distributed and widespread group of perennial flowering plants with blue or purple berries. They are classified in the section ''Cyanococcus'' within the genus ''Vaccinium''. ''Vaccinium'' also includes cranberries, bilberries, huckleberries and Madeira blueberries. Commercial blueberries—both wild (lowbush) and cultivated (highbush)—are all native to North America. The highbush varieties were introduced into Europe during the 1930s. Blueberries are usually prostrate shrubs that can vary in size from to in height. In commercial production of blueberries, the species with small, pea-size berries growing on low-level bushes are known as "lowbush blueberries" (synonymous with "wild"), while the species with larger berries growing on taller, cultivated bushes are known as "highbush blueberries". Canada is the leading producer of lowbush blueberries, while the United States produces some 40% of the world supply of highbush blueberries. Origin and h ...

Fritillaria Affinis
''Fritillaria affinis'', the chocolate lily, is a highly variable species of flowering plant in the lily family Liliaceae native to western North America. Description It grows from a bulb, which resembles a small mass of rice grains. The stems are tall. The flowers are produced in the spring, nodding, , yellowish or greenish brown with a lot of yellow mottling to purplish black with little mottling, or yellow-green mottled with purple. The leaves are in whorls. There are two varieties: *''Fritillaria affinis'' var. ''affinis'': This is the more common and widespread variant, occurring throughout the plant's range. It can be differentiated by its strong mottling pattern. Its bulb has 2 to 20 small scales. *''Fritillaria affinis'' var. ''tristulis'': This variant is much less widespread; it is found only in Marin County on the north coast of California. It has a much more subtle mottling pattern and is generally darker overall. Its bulb has 60 to 100 small scales. Distribu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dodecatheon
''Primula'' sect. ''Dodecatheon'' is a section of herbaceous flowering plants in the family Primulaceae. ''Primula'' species in this section were formerly placed in a separate genus, ''Dodecatheon''. The species have basal clumps of leaves and nodding flowers that are produced at the top of tall stems rising from where the leaves join the crown. The genus is largely confined to North America and part of northeastern Siberia. Common names include shooting star, American cowslip, mosquito bills, mad violets, and sailor caps. A few species are grown in gardens for their showy and unique flower display. The stamens are thrust out with the sepals bent back. The flowers are pollinated by bees, which grab hold of the petals, and gather pollen by vibrating the flowers by buzzing their wings (buzz pollination). The vibration releases pollen from the anthers. Taxonomy Carl Linnaeus created the genus ''Dodecatheon'' in ''Species Plantarum'' in 1753. ''Dodecatheon'' could be distinguished ...
