The Mitre (Alaska)
The Mitre is a mountain summit located in the western Chugach Mountains, in Anchorage Municipality in the U.S. state of Alaska. The mountain is situated in Chugach State Park, east of Anchorage, northeast of Bellicose Peak, and south-southeast of Eklutna Lake. The nearest higher peak is Benign Peak, to the west-northwest, on the opposite side of the Eklutna Glacier. Although modest in elevation, relief is significant since the western aspect of the mountain rises 4,000 feet above this glacier in approximately half a mile. In Europe, "mitre" is the term used for a sharp, symmetrical rocky peak such as this one. The Mitre's descriptive name was submitted for consideration by the Mountaineering Club of Alaska as suggested by Dr. Rodman Wilson (1921–2003) of Anchorage after he returned from a European vacation. The Mitre name was officially adopted in 1966 by the U.S. Board on Geographic Names. In the Denaʼina language, this mountain is known as Idlu Bena Dghelaya, meaning ' ...

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 ...

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 ...

Mountains Of Anchorage, 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 300 metres (1,000 feet) 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 a ...

Peril Peak (Alaska)
Peril Peak is a mountain summit in Alaska, United States. Description Peril Peak is located east of Anchorage in the western Chugach Mountains. It ranks as the 14th-highest summit within Chugach State Park. Precipitation runoff from the mountain drains to Knik Arm via the Eklutna River. Although modest in elevation, topographic relief is significant as the summit rises 2,500 feet (762 m) above the Eklutna Glacier in . History The peak was so named in 1963 by the members of the Mountaineering Club of Alaska because of the danger and difficulty involved in climbing it.Donald J. Orth, ''Dictionary of Alaska Place Names'', U.S. Government Printing Office, 1967, page 749. The mountain's toponym was officially adopted in 1964 by the United States Board on Geographic Names.United States Board on Geographic Names, ''Decisions on Geographic Names in the United States'', Decision List No. 6403, 1965, page 4.

Bashful Peak
Bashful Peak is a mountain in the U.S. state of Alaska, located in Chugach State Park. At , Bashful is the highest peak in Chugach State Park, and the highest peak in the Municipality of Anchorage. The peak carries snow year-round and several small glaciers hang from its steep western face. The peak was named in 1958 by members of the Mountaineering Club of Alaska because "it is often hidden by other peaks, ridges, or clouds." Climbing Bashful Peak is a challenging climb due to its height, loose rock, remoteness, exposure, and the chaotic weather of the Chugach Mountains, which includes year-round snowstorms. Bashful Peak sees very few visitors, and there are no trails up the mountain itself. Climbers typically start at the Eklutna Lake trailhead, hike up the East fork of the Eklutna River, climb the beginning of Stivers Gully on Bold Peak, climb out of the gully and cross a small valley, and ascend Bashful Peak via its southern ridge.

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] |

Eklutna River
The Eklutna River () is approximately long and is located in the Southcentral region of the U.S. state of Alaska. A portion of the river flows through a canyon up to deep, emptying into the Knik Arm of Cook Inlet approximately northeast of Anchorage. This degraded anadromous stream historically originated from Eklutna Lake, which itself is fed by Eklutna Glacier. Eklutna River is now fed primarily by groundwater before being joined by Thunderbird Creek.Eklutna Hydroelectric Project. (2020, September).

Cook Inlet
Cook Inlet ( tfn, Tikahtnu; Sugpiaq: ''Cungaaciq'') stretches from the Gulf of Alaska to 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 watershed is the most populated watershed in Alaska. The watershed covers about of southern Alaska, east of the Aleutian Range, south and east of the Alaska Range, receiving water from its tributaries, the Knik River, the Little Susitna River, and the Susitna and Matanuska rivers. The watershed includes the drainage areas of Denali (formerly named Mount McKinley). Within the watershed there are several national parks and the active volcano Mount Redoubt, along with three other historically active volcanoes. Cook Inlet provides navigable access to the port of Anchorage at the northern end, and to the smaller Homer port fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
