Mount Adolph Knopf
Mount Adolph Knopf is a glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. It is situated north-northwest of Juneau, Alaska, Juneau to the western side of the Juneau Icefield, on land managed by Tongass National Forest. Topographic relief is significant as the summit rises 2,200 feet (670 m) above the Eagle Glacier in and 3,800 feet (1,158 m) above the Thiel Glacier in . Precipitation runoff from the mountain's slopes drains to Lynn Canal. Climate Based on the Köppen climate classification, Mount Adolph Knopf is located in a subpolar oceanic climate zone, with long, cold, wet winters, and cool summers. Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Mountains
The Coast Mountains (french: La chaîne Côtière) 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 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 and Boundary Ranges, and the northern end of the 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 an extensive chain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. 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'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Alaska
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Horn Spire
Horn Spire is a mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. The peak is situated between the Thiel Glacier and Battle Glacier at the northwest extent of the Juneau Icefield, north-northwest of Juneau, Alaska, and east of Lynn Canal, on land managed by Tongass National Forest. Horn Spire is the highest point of the Icefall Spires, and although modest in elevation, relief is significant since the north face of the mountain rises over 4,700 feet above the Thiel Glacier in less than one mile. The peak's descriptive name was submitted in 1965 by Maynard Miller, director of the Juneau Icefield Research Project, and officially adopted that same year by the U.S. Board on Geographic Names. The first ascent of the peak was made June 30, 1973, by Dick Benedict, Gerry Buckley, Craig Lingle, and Bruce Tickell. Climate Based on the Köppen climate classification, Horn Spire has a subarctic climate with cold, snowy winters, and cool su ...

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 separate Alaska from Washington 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. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent. 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 Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Ernest Gruening
Mount Ernest Gruening is a glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. The long ridge-like mountain is situated between the Herbert Glacier and Eagle Glacier at the west edge of the Juneau Icefield, northwest of Juneau, Alaska, and east of Favorite Channel, on land managed by Tongass National Forest. Although modest in elevation, relief is significant since the east face of the mountain rises over 3,500 feet above the Herbert Glacier in less than one mile, and the west aspect rises 5,800 feet above the Eagle River valley in two miles. History This mountain had been called "Goat Mountain" and "Thane Mountain" until it was officially named in 1968 after Dr. Adolph Knopf, a geologist with the United States Geological Survey who studied this area. The mountain's toponym was officially changed in 1976 by the U.S. Board on Geographic Names to honor Ernest Gruening () (1887–1974), known as "the father of Alaska s ...

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 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 receive by far the most rain in Arabia. * The Western Ghats that run along India's western coast. * The Grea ...
