Mount Bagot
Mount Bagot is a 2,181-metre (7,156-foot) mountain summit located on, and in part defining, the international border between British Columbia, Canada, and Alaska, United States. Description Mount Bagot, also known as Boundary Peak 107, is located in the Boundary Ranges of the Coast Mountains. The true summit is set 200 metres inside Canada and the lower Southwest Peak (7,087+ ft, 2,160+ m) lies directly on the border, from the main summit. The Southwest Peak is situated southeast of Skagway on the boundary shared by Haines Borough and Skagway Borough, and on land managed by Tongass National Forest. Although modest in elevation, relief is significant as the west slope rises 1,720 metres (5,650 ft) in two kilometres (1.2 mile). Precipitation runoff and glacial meltwater from the mountain drains to Lynn Canal via the Katzehin River. The nearest higher neighbor is the Sawtooth Range, four miles (6.5 km) to the north. The first ascent of the summit was made on August ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Mountains
The Coast Mountains () are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the British Columbia Coast, Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific Ranges, Pacific and Boundary Ranges, and the northern end of the volcano, volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordilleraa Spanish term for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynn Canal
Lynn Canal is an inlet (not an artificial canal) into the mainland of southeast Alaska. Lynn Canal runs about from the inlets of the Chilkat River south to Chatham Strait and Stephens Passage. At over in depth, Lynn Canal is the deepest fjord in North America (outside Greenland) and one of the deepest and longest in the world. The northern portion of the canal braids into the respective Chilkat, Chilkoot, and Taiya Inlets. The Tlingit are the indigenous people of the Lynn Canal's shores and waterways. The inlet was explored for the Royal Navy by Joseph Whidbey in 1794 and named by George Vancouver for his birthplace, King's Lynn, Norfolk, England. Lynn Canal was frequently visited by maritime fur traders from at least 1800. The ''Atahualpa'' visited in 1801 and its log mentions an earlier trading visit by an unidentified ship. In April 1811 the American maritime fur trader Samuel Hill, captain of ''Otter'', battled the Chilkat Tlingit in the Chilkat Inlet of Lynn Ca ...

List Of Boundary Peaks Of The Alaska–British Columbia/Yukon Border
This is a list of Boundary Peaks of the Alaska–British Columbia border, including those on the Alaska–Yukon border, being those peaks named as border-points of the Canada–United States border as a result of the Alaska Boundary Settlement of 1903 and associated later surveys. Brass or concrete survey markers were placed on the summits of the "accessible" peaks designated in the treaty, positioned such that from any one marker a surveyor could see both the previous and the next markers along the boundary line. This was done so that if ever a question arose about jurisdiction anywhere along the border, a determination could be made by sighting between two markers. Other peaks named in the treaty but not in the numbered-peak series include T Mountain, in the Stikine Icecap area (). Other peaks on the boundary but not named in the treaty include an unnumbered Boundary Peak in the Icefield Ranges immediately north of the Alsek River () and Mount Vern Ritchie, to the north ...

Geography Of Alaska
Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About of Canadian territory consisting of British Columbia (in Canada) separate Alaska from Washington U.S. state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. The state is bordered by Yukon and British Columbia, Canada to the east, the Gulf of Alaska and the Pacific Ocean to the south, Russia (Chukotka Autonomous Okrug), Bering Sea, the Bering Strait, and the Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere, it is technically both the westernmost and easternmost state in the United States, as well as also being the northernmo ...

Juneau Icefield
The Juneau Icefield is an ice field located just north of Juneau, Alaska, Juneau, Alaska, continuing north through the border with British Columbia, extending through an area of in the Coast Mountains, Coast Range ranging north to south and east to west. The icefield is the source of many glaciers, including the Mendenhall Glacier and the Taku Glacier. The icefield is home to over 40 large valley glaciers and 100 smaller ones. The Icefield serves as a tourist attraction with many travellers flown in by helicopter for quick walks on the deep ice and the massive, awe-inspiring moist crevasses. The icefield, like many of its glaciers, reached its maximum glaciation point around 1700 and has been in retreat since. Much of the icefield is contained within the Tongass National Forest. Since 1948, the Juneau Icefield Research Program has monitored glaciers of the Juneau Icefield. On the west side of the icefield, from 1946-2009, the terminus of the Mendenhall Glacier has retreated over ... [...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 ...

Geographical Names Board Of Canada
The Geographical Names Board of Canada (GNBC) is a national committee with a secretariat in Natural Resources Canada, part of the Government of Canada, which authorizes the names used and name changes on official federal government maps of Canada. History It was created in December 1897, by Order in Council, as the Geographic Board of Canada. It consisted of one Board member from each of four Government of Canada departments, as well as the Surveyor General of Dominion Lands, while a secretariat was provided by the then-extant Department of the Interior. In December 1899, the Order in Council was amended to give the Canadian provinces and territories the right to nominate one official, each, to be a Board member. The board was succeeded by the Canadian Board on Geographic Names in 1948, then reorganized as the Canadian Permanent Committee on Geographic Names (CPCGN) in 1961. Structure , the Board consists of 27 members, one from each of the provinces and territories, and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rush–Bagot Treaty
The Rush–Bagot Treaty or Rush–Bagot Disarmament was a treaty between the United States and Great Britain limiting naval armaments on the Great Lakes and Lake Champlain, following the War of 1812. It was ratified by the United States Senate on April 16, 1818, and was confirmed by Canada, following Confederation in 1867. The treaty provided for a large demilitarization of lakes along the international boundary, where many British naval arrangements and forts remained. The treaty stipulated that the United States and British North America could each maintain one military vessel (no more than 100 tons burden) as well as one cannon (no more than eighteen pounds) on Lake Ontario and Lake Champlain. The remaining Great Lakes permitted the United States and British North America to keep two military vessels "of like burden" on the waters armed with "like force". The treaty, and the separate Treaty of 1818, laid the basis for a demilitarized boundary between the U.S. and British No ...
