Mount Newton (Yukon)
Mount Newton is a mountain summit in Yukon, Canada. Description Mount Newton is part of the Saint Elias Mountains in Kluane National Park where it ranks as the 22nd-highest summit in Canada. The remote mountain is highly glaciated and surrounded by the Seward and Newton glaciers. The nearest higher neighbor is Mount Saint Elias, to the southwest, and Mount Logan is to the northeast. Topographic relief is significant as the summit rises approximately 1,700 metres (5,577 ft) above the head of the Newton Glacier in . Etymology The mountain's toponym was officially adopted in 1917 by the Geographical Names Board of Canada to honor US geologist Henry Newton (1845–1877), grandson of Sir Isaac Newton and author of a report on the geology of the Black Hills that confirmed gold there.

Saint Elias Mountains
The Saint Elias Mountains () are a subgroup of the Pacific Coast Ranges, located in southeastern Alaska in the United States, Southwestern Yukon and the very far northwestern part of British Columbia in Canada. The range spans Wrangell-St. Elias National Park and Preserve in the United States and Kluane National Park and Reserve in Canada and includes all of Glacier Bay National Park in Alaska. In Alaska, the range includes parts of the city/borough of Yakutat and the Hoonah-Angoon and Valdez-Cordova census areas. This mountain range is named after Mount Saint Elias, which in turn was named in 1741 by the Danish-born Russian explorer Vitus Bering. Geology The Saint Elias Mountains form the highest coastal mountain range on Earth. It formed due to the subduction of the Yakutat microplate underneath the North American Plate. The Yakutat microplate is a wedge shaped oceanic plateau with a thickness of . Similar to the adjacent Pacific Plate, which has a crustal thickness of ...

Newton–Jenney Party
The Newton–Jenney Party of 1875, led by Henry Newton and Walter P. Jenney, and escorted by a military detachment led by Lieutenant Colonel Richard I. Dodge, and known also as the Jenney-Newton Party, was a scientific expedition sponsored by the United States Geological Survey to map the Black Hills of South Dakota. The Newton-Jenney expedition was established in response to the Black Hills Gold Rush, which had been escalated the previous year by General George Armstrong Custer's expedition into the Black Hills. The Newton–Jenney Party included many figures who would gain notoriety in the 19th century, including Calamity Jane, Dr. Valentine McGillycuddy, and California Joe Milner. The expedition confirmed Custer's claims of gold and prompted an increase of miners in the Black Hills region, which in turn antagonized events leading to the Great Sioux War of 1876-77 The Great Sioux War of 1876, also known as the Black Hills War, was a series of battles and negotiations ...

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...

List Of The Highest Major Summits Of Canada
The following sortable table comprises the 150 highest mountain peaks of Canada with at least of topographic prominence. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. #The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. Five major Canadian summits exceed , 11 exceed elevation, 19 exceed , 41 exceed , 69 exceed , and 125 major summits exceed elevation. __TOC__ Highest major summits Of these 150 highest major summits of Canada, 102 are located in British Columbia, 37 in Yukon, 13 in Alberta, two in Nunavut, and one in the Northwest Territories. Three of these summits lie on the British Columbia-Alberta border and two lie on the British Columbia-Yukon bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orographic Lift
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain shadowing, leeward winds, and associated clouds. Precipitation Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: * The Mogollon Rim in central Arizona * The western slope of the Sierra Nevada range in California. * The western slope of the Wasatch Range in Utah. Specifically the Little and Big Cottonwood Canyons. * The mountains near Baja California North – specifically La Bocana to Laguna Hanson. * The windward slopes of Khasi and Jayantia Hills (see Mawsynram) in the state of Meghalaya in India. * The Western Highlands of Yemen, which rece ...

Gulf Of Alaska
The Gulf of Alaska ( Tlingit: ''Yéil T'ooch’'') is an arm of the Pacific Ocean defined by the curve of the southern coast of Alaska, stretching from the Alaska Peninsula and Kodiak Island in the west to the Alexander Archipelago in the east, where Glacier Bay and the Inside Passage are found. The Gulf shoreline is a combination of forest, mountain and a number of tidewater glaciers. Alaska's largest glaciers, the Malaspina Glacier and Bering Glacier, spill out onto the coastal line along the Gulf of Alaska. The coast is heavily indented with Cook Inlet and Prince William Sound, the two largest connected bodies of water. It includes Yakutat Bay and Cross Sound. Lituya Bay (a fjord north of Cross Sound, and south of Mount Fairweather) is the site of the largest recorded tsunami in history. It serves as a sheltered anchorage for fishing boats. The Gulf of Alaska is considered a Class I, productive ecosystem with more than 300 grams of carbon per square meter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra Climate
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (), but no month with an average temperature in excess of . If the climate occurs at high elevations, it is known as alpine climate. Despite the potential diversity of climates in the ''ET'' category involving precipitation, extreme temperatures, and relative wet and dry seasons, this category is rarely subdivided. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes. The amount of native tundra biomass depends more on the local temperature than the amount of precipitation. Tundra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Alaska Boundary Dispute
The Alaska boundary dispute was a territorial dispute between the United States and the United Kingdom of Great Britain and Ireland, which then controlled Canada's foreign relations. It was resolved by arbitration in 1903. The dispute had existed between the Russian Empire and Britain since 1821, and was inherited by the United States as a consequence of the Alaska Purchase in 1867. The final resolution favored the American position, as Canada did not get an all-Canadian outlet from the Yukon gold fields to the sea. The disappointment and anger in Canada was directed less at the United States, and more at the British government for betraying Canadian interests in favor of healthier Anglo-American relations. Background 1825–1897 In 1825 Russia and the United Kingdom signed a treaty to define the borders of their respective colonial possessions, the Anglo-Russian Convention of 1825. Part of the wording of the treaty was that: The vague phrase "the mountains parallel to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Israel Russell
Israel Cook Russell, LL.D. (December 10, 1852 – May 1, 1906) was an American geologist and geographer known for his seminal work on paleolakes of the Great Basin and exploration of Alaska in the late 19th century. Early life and education Russell was born at Garrattsville, New York, on December 10, 1852. He received B.S. and C.E. degrees in 1872 from the University of the City of New York (now New York University), and later studied at the School of Mines, Columbia College. Career In 1874 he accompanied one of the parties sent out by the United States government to observe the transit of Venus, and was stationed at Queenstown, New Zealand. On his return in 1875 he was appointed assistant in geology at the School of mines, and in 1878 he became assistant geologist on the United States geological and geographical survey west of the 100th meridian. In 1880, he became a member of the United States Geological Survey (USGS). Between 1881 and 1885 he worked at Mono Lake in east-ce ...
