Alaska (; Aleut: Alax?sxax?; Inupiaq: Alaasikaq; Alutiiq: Alas'kaaq; Tlingit: Anáaski; Russian: , romanized: Alyaska) is a U.S. state in the northwest extremity of the United States West Coast, just across the Bering Strait from Asia. The Canadian province of British Columbia and territory of Yukon border the state to the east and southeast. 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--southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. It is the largest U.S. state 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 United States Census Bureau in 2015--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. United States armed forces bases and tourism are also a significant part of the economy.
On March 30, 1867, the United States purchased Alaska from the Russian Empire for 7.2 million U.S. dollars, or 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. Read more...

The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi). A boar (adult male) weighs around 350-700 kg (772-1,543 lb), while a sow (adult female) is about half that size. Polar bears are the largest land carnivores currently in existence, rivaled only by the Kodiak bear. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.
Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect. For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures. Historically, the polar bear has also been known as the white bear. It is sometimes referred to as the nanook, based on the Inuit term nanuq. Read more...

Richard Louis Proenneke (; May 4, 1916 - April 20, 2003) was an American self-educated naturalist who lived alone for nearly thirty years in the mountains of Alaska in a log cabin that he constructed by hand near the shore of Twin Lakes. Proenneke hunted, fished, raised and gathered his own food, and also had supplies flown in occasionally. He documented his activities in journals and on film, and also recorded valuable meteorological and natural data. The journals and film were later used by others to write books and produce documentaries about his time in the wilderness. Read more...
