Mount Williams (Alaska)
Mount Williams is a glaciated mountain summit located in the Chugach Mountains in the U.S. state of Alaska. The peak is situated northeast of Cordova, and northwest of Mount O'Neel, on land managed by Chugach National Forest. Although modest in elevation, relief is significant as it rises over 5,000 feet (1,500 m) in less than one mile from the immense Childs Glacier. The peak was named in 1910 by Lawrence Martin for Alfred Williams, assistant engineer for the Copper River and Northwestern Railway, which built a $1,500,000 steel bridge across the Copper River near this mountain in 1909-1910. The mountain's name was officially adopted in 1930 by the U.S. Board on Geographic Names. Climate Based on the Köppen climate classification, Mount Williams is located in a subpolar oceanic climate An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitude ...

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 ...

Miles Glacier Bridge
The Miles Glacier Bridge, also known as the Million Dollar Bridge, was built in the early 1900s across the Copper River (Alaska), Copper River fifty miles from Cordova, Alaska, Cordova in what is now the U.S. state of Alaska. It is a multiple-span Pennsylvania truss bridge which completed a railroad line for the Copper River and Northwestern Railway, built by J. P. Morgan and the Guggenheim family to haul copper from the old mining town of Kennicott, Alaska, Kennicott, now located within the Wrangell–St. Elias National Park and Preserve, to the port of Cordova. It earned its nickname because of its $1.4 million cost, well recouped by the about $200 million worth of copper ore which was shipped as a result of its construction. Current access to the bridge is limited to jet boat travel up the Copper River or boat travel downriver from Chitina, Alaska, Chitina due to the erosion along the Copper River Highway, and there is currently no access by road. The cost of repairs has preve ... [...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 separate Alaska from Washington 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. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent. 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 Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere ... [...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 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 receive by far the most rain in Arabia. * The Western Ghats that run along India's western coast. * The Grea ...

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. Ecology The Gulf of Alaska is considered a Class I, productive ecosystem with more than 300 grams of carbon per square meter per year ...

Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and 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 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...

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] |
Copper River (Alaska)
The Copper River or Ahtna River (), Ahtna Athabascan ‘Atna’tuu (), "river of the Ahtnas", Tlingit Eeḵhéeni (), "river of copper", is a 290-mile (470 km) river in south-central Alaska in the United States. It drains a large region of the Wrangell Mountains and Chugach Mountains into the Gulf of Alaska. It is known for its extensive delta ecosystem, as well as for its prolific runs of wild salmon, which are among the most highly prized stocks in the world. The river is the tenth largest in the United States, as ranked by average discharge volume at its mouth. Description The Copper River rises out of the Copper Glacier, which lies on the northeast side of Mount Wrangell, in the Wrangell Mountains, within Wrangell-Saint Elias National Park. It begins by flowing almost due north in a valley that lies on the east side of Mount Sanford, and then turns west, forming the northwest edge of the Wrangell Mountains and separating them from the Mentasta Mountains to the northea ...

Copper River And Northwestern Railway
The Copper River and Northwestern Railway (CR&NW) consisted of two rail lines, the Copper River line and the Northwestern line. Michael James Heney had secured the right-of-way up the Copper River in 1904. He started building the railway from Cordova, Alaska in 1906. The town of Cordova, Alaska, was actually named by Heney on March 13, 1906, based on the original name given by Salvador Fidalgo. Both these railroads were abandoned and little remains of them. Only a 0-4-0 locomotive, "Ole", located near Goose City on a siding of the Alaska Anthracite Railroad Company is the only equipment left. Many of the holdings of the CR&NW railroad including Ole were acquired for this railroad by Mr. Clark Davis and his partners in 1908 after a major storm destroyed the Katalla area facilities in 1907. The town of Cordova would like to move Ole to a memorial site in Cordova to celebrate its role in these railroads. Ole was declared eligible for the National Register of Historic Places in ...

Chugach National Forest
The Chugach National Forest is a United States National Forest in south central Alaska. Covering portions of Prince William Sound, the Kenai Peninsula and the Copper River Delta, it was formed in 1907 from part of a larger forest reserve. The Chugach includes extensive shorelines, glaciers, forests and rivers, much of which is untouched by roads or trails. It hosts numerous bird, mammal and marine species, including extensive shorebird habitat and a bald eagle population larger than the contiguous 48 states combined. Human industry in the forest includes extensive tourism and some mining and oil and gas operations. History The area that is now Chugach was settled by the Alutiiq thousands of years ago. It was first visited by Europeans in the mid-1700s and soon settled by Russian fur traders, who trapped the native sea otters. In 1867, the US purchased Alaska from Russia and gold was found in 1888. In 1907, the Chugach National Forest was created from a portion of forest rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
