Slanting Peak
Slanting Peak is a glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. The peak is situated in the southern portion of the Juneau Icefield, northeast of Juneau, and northeast of Guardian Mountain, which is its nearest neighbor. Slanting Peak is surrounded by the North Branch Norris Glacier to its west, and Taku Glacier on the east, and set on land managed by Tongass National Forest. This peak's descriptive name was published in 1960 by the U.S. Geological Survey. Climate Based on the Köppen climate classification, Slanting Peak is located in a subarctic climate zone, with long, cold, snowy winters, and cool summers. Weather systems coming off the Gulf of Alaska are forced upwards by the Coast Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The month of July offers the most favorable weather to ...

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 ...

Taku Glacier
Taku Glacier (Lingít: ''T'aaḵú Ḵwáan Sít'i'') is a tidewater glacier located in Taku Inlet in the U.S. state of Alaska, just southeast of the city of Juneau. Recognized as the deepest and thickest alpine temperate glacier known in the world, the Taku Glacier is measured at thick. It is about long, and is largely within the Tongass National Forest. The glacier was originally named Schultze Glacier in 1883 and the Foster Glacier in 1890, but ''Taku'', the name the local Tlingit natives had for the glacier, eventually stuck. It is nestled in the Coast Mountains and originates in the Juneau Icefield. It is the largest glacier in the icefield and one of the southernmost tidewater glaciers of the northern hemisphere. The glacier, which converges with the Taku River at Taku Inlet, has a history of advancing until it blocks the river, creating a lake, followed by a dramatic break of the ice dam. The most recent of these advances occurred in 1750. The glacier has advanced ...

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 ...

Geospatial Summary Of The High Peaks/Summits Of The Juneau Icefield
The geospatial summary of the High Peaks/Summits of the Juneau Icefield is a compilation of the basic geospatial properties (location, elevation and prominence) of the peaks/summits within the general area of the Juneau Icefield located North and East of Juneau, Alaska extending north to Skagway, Alaska. The peaks are classified by elevation: 2000 m, 2050 m, 2100 m, 2150 m, 2200 m, 2250 m, 2300 m and above 2400 m. Most (216, %) of the 272 summits compiled have not been assigned an official name by the United States Geological Survey (USGS) Geographic Names Information System (GNIS) and as such are delineated as "Un-Named" (UNP in the KML file). In addition, select minor peaks are included to report those that are contained within the GNIS database and to permit assigning a location marker (coordinate) for Nunatak identification and ridge delineation for the USGS Hydrologic Unit Code boundaries for cross referencing these areal shapes to a single coordinate. The elevation of th ...

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 ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates. Like other Class D climates, they are rare in the Southern Hemisphere, only found at some isolated highland elevations. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least on ...

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 ...

Juneau, Alaska
Juneau ( ; ), officially the City and Borough of Juneau, is the List of capitals in the United States, capital of the U.S. state of Alaska, located along the Gastineau Channel and the Southeast Alaska, Alaskan panhandle. Juneau was named the capital of Alaska in 1906, when the government of what was then the District of Alaska was moved from Sitka, Alaska, Sitka as dictated by the U.S. Congress in 1900. On July 1, 1970, the City of Juneau merged with the City of Douglas, Alaska, Douglas and the surrounding Greater Juneau Borough (United States), Borough to form the current consolidated city-county, consolidated city-borough, which ranks as the second-List of United States cities by area, largest municipality in the United States by area and is larger than both Rhode Island and Delaware. Downtown Juneau is nestled at the base of Mount Juneau and it is across the channel from Douglas Island. As of the 2020 United States census, 2020 census, the City and Borough had a population ...
