Mount Madson
Mount Madson, also known as Madson Mountain, is a prominent summit in the U.S. state of Alaska. Description Mount Madson is located on the Kenai Peninsula on land managed by Chugach National Forest. It is set north of the city of Seward in the Kenai Mountains. Precipitation runoff from the mountain drains into the Kenai River drainage basin. Although modest in elevation, topographic relief is significant as the summit rises 3,800 feet (1,158 m) above Crescent Lake in 1.4 mile (2.25 km) and 4,830 feet (1,472 m) above Kenai Lake in . Madson's local name was reported in 1909 by geologists Grant and Higgins, then officially adopted in 1910 by the U.S. Board on Geographic Names.Donald J. Orth, ''Dictionary of Alaska Place Names'', U.S. Government Printing Office, 1967, page 614. John Madson was a prospector who (with William Fairman) had mineral claims at Quartz Creek northwest of the mountain. Climate Based on the Köppen climate classification, M ...

Kenai Mountains
The Kenai Mountains ( Dena'ina: ''Yaghanen Dghili'') are a mountain range in the U.S. state of Alaska. They extend northeast from the southern end of the Kenai Peninsula to the Chugach Mountains, and have an average elevation of 3,000 to 5,000 feet. The Harding and Sargent Icefields, as well as the many glaciers that emanate from them, originate in the Kenai Mountains. Several prime fish-producing rivers, including the Kenai River and the Russian River, also flow from the mountains. The Dena'ina call the mountains ''Yaghanen Dghili'', meaning "good land mountains". The name "Kenai" was first published by Constantin Grewingk in 1849, who obtained his information from I. G. Wosnesenski's account of a voyage to the area in 1842.

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 ...

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 ...

Mount McGhan
Mount McGhan is a mountain summit in Alaska, United States. Description Mount McGhan is located on the Kenai Peninsula on land managed by Chugach National Forest. It is set north of the city of Seward in the Kenai Mountains. Although modest in elevation, topographic relief is significant as the summit rises above Crescent Lake in one mile (1.6 km), and above Kenai Lake in . Precipitation runoff from the mountain drains into these two lakes which are part of the Kenai River drainage basin. The mountain was named in 1988 after Bruce McGhan (1953–1986) at the request of his widow, Debra McGhan, with the Kenai Peninsula Borough Assembly supporting the proposal to honor her late husband who died in an industrial accident.

Trail Lakes
The Trail Lakes are two lakes on the lower Kenai Peninsula, Alaska. The lakes are near the town of Moose Pass and adjacent to the Seward Highway. They are the home of a large salmon hatchery owned by the state of Alaska and operated by the Cook Inlet Aquaculture Association. The fish hatched at this facility are released into streams and lakes at various points on the peninsula, and are also the source of the salmon runs at the "fishing hole" on the Homer Spit. The hatchery was at the center of a prolonged legal battle between the Wilderness Society and the U.S. Fish and Wildlife Service. The society claimed that the hatchery was conducting commercial activity in a wilderness area, and such activity is illegal under the Wilderness Act The Wilderness Act of 1964 () is a federal land management statute meant to protect U.S. Wilderness Area, federal wilderness and to create a formal mechanism for designating wilderness. It was written by Howard Zahniser of The Wilderness Soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geology Of Alaska
The geology of Alaska includes Precambrian igneous and metamorphic rocks formed in offshore terranes and added to the western margin of North America from the Paleozoic through modern times. The region was submerged for much of the Paleozoic and Mesozoic and formed extensive oil and gas reserves due to tectonic activity in the Arctic Ocean. Alaska was largely ice free during the Pleistocene, allowing humans to migrate into the Americas. Geologic History, Stratigraphy & Tectonics Compared with other areas of the North American continent, Alaska formed in the recent geologic past. Until 200 million years ago, western North America terminated at the Rocky Mountains, 120 miles further inland than the current shoreline, until the addition of the Yukon-Tanana Terrane. The Birch Creek Schist is the oldest rock in Alaska's interior and forms the core of the Yukon-Tanana Terrane with muscovite-quartz schist, mica quartzite and graphite schist. This intensely folded and rock unit extends f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
