Matanuska Peak
Matanuska Peak is a mountain summit located in the Chugach Mountains, in Matanuska-Susitna Borough in the U.S. state of Alaska. The mountain is a major landmark in the Matanuska Valley, situated east of Palmer, and north-northeast of Pioneer Peak. The nearest higher peak is Frontier Peak, to the southeast. Matanuska Peak's name was officially approved in 1969 by the United States Geological Survey, and derives from the Matanuska River, a native name on maps since 1897. "''Matanuska''" is derived from the Russian term for the "copper river people".''Dictionary of Alaska Place Names'', Donald J. Orth author, United States Government Printing Office (1967), page 628 The Matanuska Peak Trail is a five mile one-way hike with 5,670 feet of elevation gain and minor scrambling. The months June through October offer the most favorable weather and snow-free trail conditions to climb this peak. The Matanuska Peak Challenge is a strenuous race run in August each year.

Chugach Mountains
The Chugach Mountains of southern Alaska are the northernmost of the several mountain ranges that make up the Pacific Coast Ranges of the western edge of North America. The range is about long and wide, and extends from the Knik and Turnagain Arms of the Cook Inlet on the west to Bering Glacier, Tana Glacier, and the Tana River on the east. It is bounded on the north by the Matanuska, Copper, and Chitina rivers. The highest point of the Chugach Mountains is Mount Marcus Baker, at , but with an average elevation of , most of its summits are not especially high. Even so, its position along the Gulf of Alaska ensures more snowfall in the Chugach than anywhere else in the world, an annual average of over 1500 cm (800 in).Steep, Freeskiing Documentary, 2007 The mountains are protected in the Chugach State Park and the Chugach National Forest. Near to Anchorage, they are a popular destination for outdoor activities. The Richardson Highway, Seward Highway, Portage G ...

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] |

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 peaksThis article defines a significant summit as a summit with at least of topographic prominence, and a major summit as a susexxleast of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least of topographic prominence. 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.If the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown. 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 topographic prominence of a summit is the topographic elevation difference between the s ...

Knik River
The Knik River ( Dena'ina: ''Skitnu''; Ahtna: ''Scitna’'') is a 25-mile-long (40 km) river in the U.S. state of Alaska. Its source is at Knik Glacier, from which it flows northwest and west and empties into the head of Cook Inlet's Knik Arm, near the mouth of the Matanuska River. It is bridged twice (old and new bridges) where the Old Glenn Highway crosses it near the Butte, and also bridged on the Hayflats. It is characterized by a broad flat plain with a bed of finely ground gravel and sand and silt. During windstorms, large quantities of fine material is blown from the riverbed and deposited in locations generally downstream or west. The river itself is relatively shallow and wide and considered a class I float. It drops about from the glacier to the salt water, or roughly per mile. The above the hayflats bridge is unusual in that it remains unfrozen most winters because the eklutna project discharges warmer water into the tailrace. Discharge normally is abo ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a 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° to 70°N, poleward of the humid continental climates. 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 one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Matanuska River
The Matanuska River ( Dena'ina: ''Ch'atanhtnu''; Ahtna: ''Ts'itonhna’'') is a 75-mile (121 km) long river in Southcentral Alaska, United States. The river drains a broad valley south of the Alaska Range eponymously known as the Matanuska Valley. Course Formed by the confluence of its east and south forks, the Matanuska River flows generally southwest to the Knik Arm of Cook Inlet. Downstream of its source, the river is joined by meltwater from Matanuska Glacier in the northern Chugach Mountains. From there it continues through the Matanuska Valley, between the Chugach Mountains to the south and the Talkeetna Mountains to the north. Population centers along its course include Chickaloon, Sutton, Palmer, and Butte. It enters the Knik Arm of Cook Inlet about southwest of Palmer and about northeast of Anchorage. The Glenn Highway runs roughly parallel to the river for much of its length. Highway bridges over the river, listed from source to mouth, include Glacier Park B ...

Pioneer Peak (Alaska)
Pioneer Peak (Ahtna: ''Tnel'aay''; Dena'ina: ''Dnal'iy'') is a mountain in the Chugach Mountains in the U.S. state of Alaska. Located beside the Knik River just nine miles (14.5 km) south of Palmer and about six miles outside the Municipality of Anchorage limits, it is a prominent landmark in the Matanuska-Susitna Valley, as well as a popular hiking destination. Its Ahtna name means "''the object is standing still''" and its Dena'ina name means "''the one that watches us''". The name was given in 1939 in honor of the pioneers of the Matanuska agricultural colony of the mid-1930s. The Pioneer Ridge Trail leads up the eastern shoulder, beginning below 200', it allows access to the South summit. The North summit, and true summit of Pioneer Peak does not have a trail, and advanced mountaineering techniques are required. The first ascent of this peak was made June 1936 by Vernon Haik and John Wolffe via the Northwest Face. Climate Based on the Köppen climate classificatio ...
