IntroductionAlaska (/əˈlæskə/ ⓘ ə-LASS-kə) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost state in the United States. It is a semi-exclave of the U.S., bordering the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border in the Bering Strait with Russia's Chukotka Autonomous Okrug, and closer to another continent (Asia) than any U.S. state. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean to the south. Alaska is the largest U.S. state by area—comprising more total area than the next three largest states of Texas, California, and Montana combined—and is the world's largest exclave and seventh-largest subnational division. With a population of 740,133 in 2024, it is the third-least populous and most sparsely populated state in the U.S., but the most populous territory in North America located mostly north of the 60th parallel, with more than quadruple the combined populations of Northern Canada and Greenland. Alaska contains the four largest cities in the United States by area, including the state capital of Juneau. Alaska's most populous city is Anchorage, and approximately half the state's residents live within its metropolitan area. Indigenous people have lived in Alaska for thousands of years, and it is widely believed that the region served as the entry point for the initial settlement of the Americas by way of the Bering land bridge. The Russian Empire was the first to actively colonize the area beginning in the 18th century, eventually establishing Russian America, which spanned most of the current state and promoted and maintained a native Alaskan Creole population. The expense and logistical difficulty of maintaining this distant possession prompted its sale to the U.S. in 1867 for US$7.2 million, equivalent to $162 million in 2024. 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. An abundance of natural resources—including commercial fishing and the extraction of natural gas and oil—has enabled Alaska to have one of the highest per capita incomes in the United States, despite having one of the smallest economies. U.S. Armed Forces bases and tourism also contribute to the economy; more than half of Alaska is federally owned, containing national forests, national parks, and wildlife refuges. It is among the most irreligious states and one of the first to legalize recreational marijuana. Alaska has the highest proportion of Native Americans of any U.S. state, at 22 percent.

Amchitka Island (/æmˈtʃɪtkə/; Aleut: Amchixtax̂;) is a volcanic, tectonically unstable and uninhabited island in the Rat Islands group of the Aleutian Islands in southwest Alaska. It is part of the Alaska Maritime National Wildlife Refuge. The island, with a land area of roughly 116 square miles (300 km2), is about 42 miles (68 km) long and 1 to 4 miles (1.6 to 6.4 km) wide. The area has a maritime climate, with many storms, and mostly overcast skies. Amchitka was populated for more than 2,500 years by the Aleut people, but has had no permanent population since 1832. The island has been part of the United States since the Alaska Purchase of 1867. During World War II, it was used as an airfield by US forces in the Aleutian Islands Campaign. Amchitka Island was selected by the United States Atomic Energy Commission (AEC) to be the site for underground detonations of nuclear weapons. Three such tests were carried out: Long Shot, an 80-kiloton (330 TJ) blast in 1965; Milrow, a 1-megaton (4.2 PJ) blast in 1969; and Cannikin in 1971 – at 5 Mt (21 PJ), the largest underground test ever conducted by the United States. The tests were highly controversial, with environmental groups fearing that the Cannikin explosion, in particular, would cause severe earthquakes and tsunamis. Amchitka Island is no longer used for nuclear testing. It is still monitored for the leakage of radioactive materials. (Full article...) TopicsCategoriesSelect [►] to view subcategories

The volcano forms Augustine Island, colloquially called Mount St. Augustine, in southwestern Cook Inlet in the Kenai Peninsula Borough of southcentral coastal Alaska, about 70 miles (113 km) west of Homer and about 175 miles (282 km) southwest of Anchorage. The volcano is frequently active, with major eruptions recorded in 1883, 1935, 1963–64, 1976, 1986, and 2006. Minor eruptive events were reported in 1812, 1885, 1908, 1944, and 1971. The large eruptions are characterized by an explosive onset followed by the quieter effusion of lava. Augustine Island has a land area of 32.4 square miles (83.9 km2), while West Island, just off Augustine's western shores, has 2 sq mi (5.2 km2). The irregular coastline of Augustine Island is due to the repeated catastrophic collapse of the summit dome, forming debris avalanches down the flanks and into Cook Inlet. The island is mainly made up of past eruption deposits. Scientists have been able to discern that past dome collapse has resulted in large avalanches. (Full article...)
