Alaska
From Wikinvestor
Alaska , is the largest state of the United States of America by area; it is situated in the northwest extremity of the North American continent, with Canada to the east, the Arctic Ocean to the north, and the Pacific Ocean to the west and south, with Russia further west across the Bering Strait. As of 2007, the population was 683,478 with approximately 50% residing along the Anchorage metropolitan areas.
The area that became Alaska was purchased from the Russian Empire after Western Union discontinued construction of its first electric telegraph line which ran from California, up the coast of North America, across the Bering Strait, continuing to Moscow and into the European telegraph network. Despite $3 million in U.S. investment for the Russian-American telegraph expedition, work ceased[4] upon the completion of the competing Transatlantic telegraph cable. The U.S. realized the potential of continuing the line to Moscow and sent Secretary of State William H. Seward to negotiate with the Russian Ambassador to fund the remaining phases of the telegraph line. Russia did not see the potential in funding, so Alaska was offered in exchange for the value of the Russian-American telegraph. The Russians feared that if they did not sell Russian North America, it would be taken from them by the westward expansion of the United States and Canada. They tried to play one potential purchaser off against the other to start a bidding war, but this was largely unsuccessful.
The U.S. Senate approved the purchase of Alaska from the Russian Empire on March 30, 1867, for $7.2 million at 2 cents per acre, about 5 cents per hectare. When adjusted for inflation, the total sum paid equates to approximately $111 million in today's dollars. The land went through several administrative changes before becoming an organized territory on May 11, 1912 and the 49th state of the U.S. on January 3, 1959. The name "Alaska" was already introduced in the Russian colonial time, when it was only used for the peninsula and is derived from the Aleut alaxsxaq, meaning "the mainland", or more literally, "the object towards which the action of the sea is directed." It is also known as Alyeska, the "great land", an Aleut word derived from the same root.

Geography
Alaska is one of two U.S. states not bordered by another state, Hawaii being the other. Alaska has more coastline than all the other U.S. states combined. It is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of British Columbia (Canada) separate Alaska from Washington state. Alaska is thus an exclave of the United States. It is technically part of the continental U.S., but is often not included in colloquial use; Alaska is not part of the contiguous U.S., often called "the Lower 48". Juneau, Alaska's capital city, though located on the mainland of the North American continent, is inaccessible by land—no roads connect Juneau to the rest of the North American highway system.
The state is bordered by the Yukon Territory and British Columbia, Canada, to the east, the Gulf of Alaska and the Pacific Ocean to the south, the Bering Sea, Bering Strait, and Chukchi Sea to the west and the Arctic Ocean to the north. Alaska's territorial waters touch Russia's territorial waters in the Bering Strait, though the Russian and Alaskan islands are almost 3 miles (4.8 km) apart.
Alaska is the largest state in the United States in land area at 570,380 square miles (1,477,277 km2), more than twice as large as Texas, the next largest state. Geologists have identified Alaska as part of Wrangellia, a large region consisting of multiple states and Canadian provinces in the Pacific Northwest which is actively undergoing continent building. It is larger than all but 18 sovereign countries.
Counting territorial waters, Alaska is larger than the combined area of the next three largest states: Texas, California, and Montana.
It is also larger than the combined area of the 23 smallest U.S. States and Districts: Washington, D.C., Rhode Island, Delaware, Connecticut, Hawaii, New Jersey, Massachusetts, New Hampshire, Vermont, Maryland, West Virginia, South Carolina, Maine, Indiana, Kentucky, Tennessee, Virginia, Ohio, Pennsylvania, Mississippi, Louisiana, Alabama and North Carolina.
Also, compared with territory outside the United States, Alaska is larger than Sweden, Norway, Finland, the Netherlands, and the United Kingdom combined.

The northeast corner of Alaska is dominated by the Arctic National Wildlife Refuge, which covers 19,049,236 acres (77,090 km2). Much of the northwest is covered by the larger National Petroleum Reserve–Alaska, which covers around 23,000,000 acres (93,100 km2). The Arctic is Alaska's most remote wilderness. A location in the National Petroleum Reserve–Alaska is 120 miles (190 km) from any town or village, the geographic point most remote from permanent habitation on the US mainland. The Rat Islands region in the Western Aleutians is more than 200 miles (320 km) from the tiny settlements of Attu and Adak, and may be the loneliest place in the United States. In 1971 the U.S. exploded an atomic bomb underground here, on Amchitka Island.
With its myriad islands, Alaska has nearly 34,000 miles (54,720 km) of tidal shoreline. The Aleutian Islands chain extends west from the southern tip of the Alaska Peninsula. Many active volcanoes are found in the Aleutians. Unimak Island, for example, is home to Mount Shishaldin, which is an occasionally smoldering volcano that rises to 10,000 feet (3,000 m) above the North Pacific. It is the most perfect volcanic cone on Earth, even more symmetrical than Japan's Mount Fuji. The chain of volcanoes extends to Mount Spurr, west of Anchorage on the mainland.
One of North America's largest tides occurs in Turnagain Arm, just south of Anchorage — tidal differences can be more than 35 feet (10.7 m). (Many sources say Turnagain has the second-greatest tides in North America, but several areas in Canada have larger tides.)
Alaska has more than 3 million lakes.[9][10] Marshlands and wetland permafrost cover 188,320 square miles (487,747 km2) (mostly in northern, western and southwest flatlands). Frozen water, in the form of glacier ice, covers some 16,000 square miles (41,440 km2) of land and 1,200 square miles (3,110 km2) of tidal zone. The Bering Glacier complex near the southeastern border with Yukon, Canada, covers 2,250 square miles (5,827 km2) alone.
The International Date Line jogs west of 180° to keep the whole state, and thus the entire North American continent, within the same legal day. Alaska has more acres of public land owned by the federal government than any other state.[11]
According to an October 1998 report by the United States Bureau of Land Management, approximately 65% of Alaska is owned and managed by the U.S. federal government as public lands, including a multitude of national forests, national parks, and national wildlife refuges. Of these, the Bureau of Land Management manages 87 million acres (350,000 km²), or 23.8% of the state. The Arctic National Wildlife Refuge is managed by the United States Fish and Wildlife Service. It is the World's largest wildlife Refuge, comprising 16 million acres (65,000 km2).
Of the remaining land area, the State of Alaska owns 101 million acres (410,000 km2); another 44 million acres (180,000 km2) are owned by 13 regional and dozens of local Native corporations created under the Alaska Native Claims Settlement Act. Thus, indirectly, the 84,000 Eskimo (Inuit), Aleut and American Indian inhabitants of Alaska own one-ninth of the state. Various private interests own the remaining land, totaling about 1% of the state.
Alaska is administratively divided into "boroughs", as opposed to "counties" or "parishes." The function is the same, but whereas some states use a three-tiered system of decentralization—state/county/township—most of Alaska uses only two tiers—state/borough. Owing to the low population density, most of the land is located in the Unorganized Borough which, as the name implies, has no intermediate borough government of its own, but is administered directly by the state government. Currently (2000 census) 57.71% of Alaska's area has this status, with 13.05% of the population. For statistical purposes the United States Census Bureau divides this territory into census areas. Anchorage merged the city government with the Greater Anchorage Area Borough in 1971 to form the Municipality of Anchorage, containing the city proper and the bedroom communities of Eagle River, Chugiak, Peters Creek, Girdwood, Bird, and Indian. Fairbanks has a separate borough (the Fairbanks North Star Borough) and municipality (the City of Fairbanks).
Alaska is also home of the Mount McKinley mountain range which is the largest mountain range in the United States.
Climate
The climate in Juneau and the southeast panhandle is a mid-latitude oceanic climate (Köppen climate classification Cfb) in the southern sections and a subarctic oceanic climate (Köppen Cfc) in the northern parts. On an annual basis, the panhandle is both the wettest and warmest part of Alaska with milder temperatures in the winter and high precipitation throughout the year. Juneau averages over 50 inches (1,270 mm) of precipitation a year, while other areas receive over 275 inches (6,990 mm). This is also the only region in Alaska in which the average daytime high temperature is above freezing during the winter months.
The climate of Anchorage and south central Alaska is mild by Alaskan standards due to the region's proximity to the seacoast. While the area gets less rain than southeast Alaska, it gets more snow, and days tend to be clearer. On average, Anchorage receives 16 inches (406 mm) of precipitation a year, with around 75 inches (1,905 mm) of snow, although there are areas in the south central which receive far more snow. It is a subarctic climate (Köppen Dfc) due to its short, cool summers. Barrow, Alaska is the northernmost city in the United States
The climate of Western Alaska is determined in large part by the Bering Sea and the Gulf of Alaska. It is a subarctic oceanic climate in the southwest and a continental subarctic climate farther north. The temperature is somewhat moderate considering how far north the area is. This area has a tremendous amount of variety in precipitation. The northern side of the Seward Peninsula is technically a desert with less than 10 inches (250 mm) of precipitation annually, while some locations between Dillingham and Bethel average around 100 inches (2,540 mm) of precipitation.[12]
The climate of the interior of Alaska is best described as extreme and is a good example of a true subarctic climate. Some of the highest and lowest temperatures in Alaska occur around the area near Fairbanks. The summers can have temperatures reaching into the 90s°F (the low to mid 30s °C), while in the winter, the temperature can fall below −60 °F (-52 °C). Precipitation is sparse in the Interior, often less than 10 inches (250 mm) a year, but what precipitation falls in the winter tends to stay the entire winter.
The highest and lowest recorded temperatures in Alaska are both in the Interior. The highest is 100 °F (38 °C) in Fort Yukon (which is just 8 miles (13 km) inside the arctic circle) on June 27, 1915, tied with Pahala, Hawaii as the lowest high temperature in the United States. The lowest official Alaska temperature is −80 °F (-62 °C) in Prospect Creek on January 23, 1971, one degree above the lowest temperature recorded in continental North America (in Snag, Yukon, Canada).
The climate in the extreme north of Alaska is as expected for an area north of the Arctic Circle. It is an Arctic climate (Köppen ET) with long, very cold winters and short, cool summers. Even in July, the average low temperature is barely above freezing in Barrow, at 34 °F (1 °C). Precipitation is light in this part of Alaska, with many places averaging less than 10 inches (250 mm) per year, mostly in the form of snow which stays on the ground almost the entire year.
Demographics
The United States Census Bureau, as of July 1, 2008, estimated Alaska's population at 686,293, which represents an increase of 59,362, or 9.5%, since the last census in 2000. This includes a natural increase since the last census of 60,994 people (that is 86,062 births minus 25,068 deaths) and a decrease due to net migration of 5,469 people out of the state. Immigration from outside the United States resulted in a net increase of 4,418 people, and migration within the country produced a net loss of 9,887 people. In 2000 Alaska ranked 48th out of 50 states by population. Alaska is the least densely populated state, at 1.0 people per square mile (0.42/km²), with the next state, Wyoming, at 5.1 per square mile (1.97/km²). It is the largest U.S. state by area, and the 6th wealthiest (per capita income).
Economy
The 2005 gross state product was $39.9 billion, 45th in the nation. Its per-capita GSP for 2006 was $43,748, 7th in the nation. The oil and gas industry dominates the Alaskan economy, with more than 80% of the state's revenues derived from petroleum extraction. Alaska's main export product (excluding oil and natural gas) is seafood, primarily salmon, cod, Pollock and crab. Agriculture represents only a fraction of the Alaskan economy. Agricultural production is primarily for consumption within the state and includes nursery stock, dairy products, vegetables, and livestock. Manufacturing is limited, with most foodstuffs and general goods imported from elsewhere. Employment is primarily in government and industries such as natural resource extraction, shipping, and transportation. Military bases are a significant component of the economy in both Fairbanks and Anchorage. Federal subsidies are also an important part of the economy, allowing the state to keep taxes low. Its industrial outputs are crude petroleum, natural gas, coal, gold, precious metals, zinc and other mining, seafood processing, timber and wood products. There is also a growing service and tourism sector. Tourists have contributed to the economy by supporting local lodging.
