The Sisters (Alaska)
The Sisters are mountain summits in Alaska, United States. Description The Sisters are located on the west coast of Baranof Island, approximately northeast of Sitka.Donald J. Orth, ''Dictionary of Alaska Place Names'', U.S. Government Printing Office, 1967, page 879. The highest peak reaches an elevation of . This mountain group is part of the Alexander Archipelago and is set on land managed by Tongass National Forest. Precipitation runoff from the mountain drains to the Indian River and Sitka Sound. Topographic relief is significant as the north slope rises over above an unnamed creek in . The landform's local name was published in 1916 by U.S. Coast and Geodetic Survey, and the toponym has been officially adopted by the U.S. Board on Geographic Names. Climate Based on the Köppen climate classification, The Sisters is located in a subpolar oceanic climate zone with long, cold, snowy winters, and cool summers.

Alexander Archipelago
The Alexander Archipelago () is a archipelago (group of islands) in North America lying off the southeastern coast of Alaska. It contains about 1,100 islands, the tops of submerged coastal mountains that rise steeply from the Pacific Ocean. Deep channels and fjords separate the islands and cut them off from the mainland. The islands shelter the northern part of the Inside Passage as it winds its way among them. The islands have Steep coast, steep, Fjord, irregular coasts and dense evergreen and temperate rain forests; most are accessible only by boat or by airplane. The vast majority of the islands are part of the Tongass National Forest. In order of land area, the List of islands of the United States by area, largest islands are Prince of Wales Island (Alaska), Prince of Wales Island, Chichagof Island, Admiralty Island, Baranof Island, Revillagigedo Island, Kupreanof Island, Kuiu Island, Etolin Island, Dall Island, Wrangell Island, Mitkof Island, Zarembo Island, Kosciusko Islan ...

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 ...

Mount Verstovia
Mount Verstovia is a prominent peak located just 2.6 miles east of the center of Sitka, Alaska, on Baranof Island Baranof Island is an island in the northern Alexander Archipelago in the Alaska Panhandle, in Alaska. The name "Baranof" was given to the island in 1805 by Imperial Russian Navy captain Yuri Lisyansky, U. F. Lisianski in honor of Alexander Andrey ..., Alexander Archipelago. The summit rises steeply from the nearby Pacific Ocean, with its lower flanks cloaked in temperate old growth rain forests and its upper regions, above 2,400 feet, being above treeline and providing excellent vistas of Sitka and the surrounding mountain and ocean environments. This peak was first named "Gora Verstovaya" in 1809 by the navigator Ivan Vasiliev. ''Gora'' translates to "mount" in Russian and ''verst'' refers to a unit of measurement equaling 0.6629 miles (or 3,500 feet), which closely resembles the actual height of Mt. Verstovia. The main summit of Mount Verstovia is called Arrow He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Lake (Alaska)
Blue Lake (Tlingit: Gajook Héen Yik.áayi) is a long reservoir located east of the town of Sitka, on the west side of Baranof Island, in the Alexander Archipelago of Southeast Alaska. Name and geology The local descriptive name was reported in 1910 by Knopf (1912, fig 4), in United States Geological Survey. Blue Lake, as its name suggests, possesses a deep blue hue to its water. Blue Lake's water sources are partially from snowpack and small glaciers from the glacially carved, U-shaped, Blue Lake valley in which it lies. Dam Blue lake was first dammed in 1913 by Sitka Wharf and Power Company. It sold its operation to the city in 1942. Floods damaged the infrastructure in 1943 and 1947. Blue Lake was dammed again in 1958, greatly expanding the lake's size from to and increasing its height from to . The dam is under construction as of 2024. It is being extended another feet higher. Dam fluctuations allow the lake elevation to vary up to . The Blue Lake dam, along with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

List Of Mountain Peaks Of Alaska
This article comprises three sortable tables of major mountain peaks of the U.S. State of Alaska. 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 first table below ranks the 100 highest major summits of Alaska by elevation. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. The second table below ranks the 100 most prominent summits of Alaska. #The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. The third table below ranks the 50 most isolated major summits of Alaska. __TOC__ Highest major summits Of the 100 highest major summits of Alaska, only Denali exceeds elevation, four peaks exceed , 23 peaks exceed , 61 peaks exceed , and 92 peaks exceed elevation. Five of these peaks lie on the internation ... [...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] |
Oceanic Climate
An oceanic climate, also known as a marine climate or maritime climate, is the temperate climate sub-type in Köppen climate classification, Köppen classification represented as ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool to warm summers and cool to mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 40 and 60 degrees latitude, with subpolar versions extending to 70 degrees latitude in some coastal areas. Other varieties of climates usually classified together with these include subtropical highland climates, represented as ''Cwb'' or ''Cfb'', and subpolar oceanic or cold subtropical highland climates, represented as ''Cfc'' or ''Cwc''. Subtropical highland climates occur in some mountainous parts of the subtropics or tropics, some of which have monsoon influence, while their cold variants an ...

Topographic Relief
Terrain (), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Bathymetry is the study of underwater relief, while hypsometry studies terrain relative to sea level. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drainage characteristics, drainage systems, groundwater systems, water ...

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 ...

Sitka Sound
Sitka Sound is a body of water near the city of Sitka, Alaska. It is bordered by Baranof Island to the south and the northeast, by Kruzof Island to the northwest and by the Pacific Ocean to the southwest. During the early 19th century it was a major locus of the maritime fur trade. Naming history Sitka Sound was named Ensenada de Susto by Juan de la Bodega on 15 August 1775. It was later named Norfolk Sound by James Cook Captain (Royal Navy), Captain James Cook (7 November 1728 – 14 February 1779) was a British Royal Navy officer, explorer, and cartographer famous for his three voyages of exploration to the Pacific and Southern Oceans, conducted between 176 ....
