White Mountains (Alaska)
The White Mountains is a mountain range in the Yukon-Koyukuk Census Area of the U.S. state of Alaska. It lies between Beaver Creek and Preacher Creek, and was named by prospectors for its composition of white limestone. The range reaches a maximum elevation of . Some of the range is located in the White Mountains National Recreation Area, a wilderness just north of Fairbanks. The White Mountains and Ray Mountains together constitute the Yukon-Tanana Uplands, an area of low mountain ranges and high ground in Interior Alaska Interior Alaska is the central region of Alaska's territory, roughly bounded by the Alaska Range to the south and the Brooks Range to the north. It is largely wilderness. Mountains include Denali in the Alaska Range, the Wrangell Mountains, and ....

White is the lightness, lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully diffuse reflection, reflect and scattering, scatter all the visible spectrum, visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical archite ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types.

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, ...

Beaver Creek (Alaska)
Beaver Creek (Upper Tanana: ''Taatthee Niign'') is a tributary of the Yukon River in the U.S. state of Alaska. The creek begins at the confluence of Champion and Bear creeks in the White Mountains National Recreation Area, about north of Fairbanks. From there it flows west around the southern end of the White Mountains, then northeast into the Yukon Flats National Wildlife Refuge, then west into the Yukon River downstream of Beaver. In 1980, The Alaska National Interest Lands Conservation Act designated the upper of Beaver Creek as part of the National Wild and Scenic Rivers System. Most of this lies within the recreation area, but the last are in the wildlife refuge. Description Beaver Creek flows from its headwaters through thick forest of white spruce and paper birch forests and tundra on the high slopes of the White Mountains, where limestone peaks reach on the creek's north and east side. The creek has plentiful gravel bars, and willows grow on its banks. The l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preacher Creek
A preacher is a person who delivers sermons or homilies on religious topics to an assembly of people. Less common are preachers who preach on the street, or those whose message is not necessarily religious, but who preach components such as a moral or social worldview or philosophy. History Preachers are common throughout most cultures. They can take the form of a Christian minister on a Sunday morning, or an Islamic Imam. A Muslim preacher in general is referred to as a '' dā‘ī'', while one giving sermons on a Friday afternoon is called a ''khatib''. The sermon or homily has been an important part of Christian services since Early Christianity, and remains prominent in both Roman Catholicism and Protestantism. Lay preachers sometimes figure in these traditions of worship, for example the Methodist local preachers, but in general preaching has usually been a function of the clergy. The Dominican Order is officially known as the ''Order of Preachers'' (''Ordo Praedicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landforms Of Yukon–Koyukuk Census Area, Alaska
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.
