Reseña del libro "Alaska: Aurora Borealis (en Inglés)"
Alaska is a U.S. state in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east, its most extreme western part is Attu Island, and it has a maritime border with Russia (Chukotka Autonomous Okrug) to the west across the Bering Strait. To the north are the Chukchi and Beaufort seas-the southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. It is the largest state in the United States by area and the seventh largest subnational division in the world. In addition, it is the 3rd least populous and the most sparsely populated of the 50 United States; nevertheless, it is by far the most populous territory located mostly north of the 60th parallel in North America: its population-estimated at 738,432 by the U.S. Census Bureau in 2015[5]- is more than quadruple the combined populations of Northern Canada and Greenland. Approximately half of Alaska's residents live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy.The United States purchased Alaska from the Russian Empire on March 30, 1867, for 7.2 million U.S. dollars at approximately two cents per acre ($4.74/km2). The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959.The Interior is the largest region of Alaska; much of it is uninhabited wilderness. Fairbanks is the only large city in the region. Denali National Park and Preserve is located here. Denali is the highest mountain in North America.Alaska has more than three million lakes. Marshlands and wetland permafrost cover 188,320 square miles (487,747 km2) (mostly in northern, western and southwest flatlands). Glacier ice covers about 28,957 square miles (75,000 km2) of Alaska. The Bering Glacier is the largest glacier in North America, covering 2,008 square miles (5,200 km2) alone.In 1960, the Census Bureau reported Alaska's population as 77.2% White, 3% Black, and 18.8% American Indian and Alaska Native.According to the 2010 United States Census, Alaska, had a population of 710,231. In terms of race and ethnicity, the state was 66.7% White (64.1% Non-Hispanic White), 14.8% American Indian and Alaska Native, 5.4% Asian, 3.3% Black or African American, 1.0% Native Hawaiian and Other Pacific Islander, 1.6% from Some Other Race, and 7.3% from Two or More Races. Hispanics or Latinos of any race made up 5.5% of the population. As of 2011, 50.7% of Alaska's population younger than one year of age belonged to minority groups (i.e., did not have two parents of non-Hispanic white ancestry).
