Slope Mountain (Chigmit Mountains)
Slope Mountain is a summit in the US state of Alaska. Description Slope Mountain is located in the Chigmit Mountains of the Aleutian Range. It is set along the west shore of Cook Inlet and within Lake Clark National Park and Preserve. The mountain is situated southwest of Anchorage, southwest of Kenai, and east of Mount Iliamna volcano. Precipitation runoff from the mountain drains into Johnson River and Cook Inlet. Although modest in elevation, topographic relief is significant as the summit rises up from tidewater in . The mountain's local descriptive name was reported in 1910 by G. C. Martin, U.S. Geological Survey, and the toponym has been officially adopted by the U.S. Board on Geographic Names. Climate Based on the Köppen climate classification, Slope Mountain is located in a subarctic climate zone, with long, cold, snowy winters, and cool summers. Winter temperatures can drop below 0 °F with wind chill factors below −10 °F. The months May through June ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chigmit Mountains
The Chigmit Mountains are a subrange of the Aleutian Range in the Kenai Peninsula and Lake and Peninsula Boroughs of the U.S. state of Alaska. Location They are located at the northeastern end of the Aleutian range, on the west side of Cook Inlet, roughly 120 miles (200 km) southwest of Anchorage. The closest major towns to the range are Kenai and Homer, across Cook Inlet on the west side of the Kenai Peninsula. To the north, the Chigmits are bordered by the Tordrillo Mountains, and on the northwest, by the Neacola Mountains. Cook Inlet marks the eastern boundary of the range, while on the west, the mountains fade out into the hills and lowlands of Lake Clark National Park and Preserve. On the south and southwest, the Chigmits abut the continuation of the Aleutian Range into the Alaska Peninsula. Geological composition The Chigmits, along with most of the Aleutian Range, are volcanic, and include two prominent stratovolcano A stratovolcano, also known as a compo ...

Kenai, Alaska
Kenai (, ; Dena'ina: ; , ''Kenay'') is a city in the Kenai Peninsula Borough in the U.S. state of Alaska. By road, it is 158 miles southwest of Anchorage. The population was 7,424 as of the 2020 census, up from 7,100 in 2010, the fifteenth-most populated city in the state. History The city of Kenai is named after the local Dena'ina word 'ken' or 'kena', which means 'flat, meadow, open area with few trees; base, low ridge', according to the Dena'ina Topical Dictionary by James Kari, Ph.D., published in 2007. This describes the area along the mouth and portion of the Kenai River near the City of Kenai. Archaeological evidence suggests that the area was first occupied by the Kachemak people from 1000 B.C., until they were displaced by the Dena'ina Athabaskan people around 1000 A.D. Before the arrival of the Russians, Kenai was a Dena'ina village called ''Shk'ituk't'', meaning "where we slide down." When Russian fur traders first arrived in 1741, about 1,000 Dena'ina l ...

Mountains Of Kenai Peninsula Borough, 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 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 climate, mountains te ...

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 ...

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 ... [...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 ...

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 ...

Aleutian Range
The Aleutian Range is a major mountain range located in southwest Alaska. It extends from Chakachamna Lake (80 miles/130 km southwest of Anchorage) to Unimak Island, which is at the tip of the Alaska Peninsula. It includes all of the mountains of the Peninsula. The Aleutian Range is special because of its large number of active volcanoes, which are also part of the larger Aleutian Arc. The mainland part of the range is about 600 miles (1000 km) long. The Aleutian Islands are (geologically) a partially submerged western extension of the range that stretches for another 1,600 km (1000 mi). However the official designation "Aleutian Range" includes only the mainland peaks and the peaks on Unimak Island. The range is almost entirely roadless wilderness. Katmai National Park and Preserve, a large national park within the range, must be reached by boat or plane. The core Aleutian Range can be divided into three mountain groups. Listed from southwest to northeast, they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cook Inlet
Cook Inlet (; Sugpiaq language, Sugpiaq: ''Cungaaciq'') stretches from the Gulf of Alaska to Anchorage, Alaska, Anchorage in south-central Alaska. Cook Inlet branches into the Knik Arm and Turnagain Arm at its northern end, almost surrounding Anchorage. On its southern end, it merges with Shelikof Strait, Stevenson Entrance, Kennedy Entrance and Chugach Passage. The Cook Inlet and both its arms are bodies of brackish water, containing a turbid mix of ocean salt-water and freshwater runoff from the various rivers and streams. The narrow channel of the inlet funnels the tides creating very fast-moving currents, rip tides, and occasional bore tides. Cook Inlet watershed is the most populated watershed in Alaska. The drainage basin, watershed covers about of southern Alaska, east of the Aleutian Range, south and east of the Alaska Range, receiving water from its tributaries, which include the Knik River, the Little Susitna River, the Susitna River, Susitna and Matanuska River, Ma ...

Summit
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent solid ice (snow height). The highest summit in the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
